In some cases, the precise mechanism for the fetomaternal transfer is not known (proximal gut obstruction, renal agenesis), and may be secondary to diminished fetal gut degradation or elevated fetal serum concentrations of AFP. This can happen when the due date has been miscalculated and you are earlier in your pregnancy than the initial estimate. Levels rise during the second trimester. AFP is a protein normally made by the baby’s liver. In rare cases, the vein may swell up resulting in a condition called phlebitis, which can be treated with a warm compress applied at regular intervals. Sagittal and transaxial images of the spine should demonstrate an intact dorsal skin line. Unfortunately, this is impossible owing to considerable overlap in MS-AFP levels between normal and abnormal pregnancies. In normal pregnancies, AFP from fetal serum enters the amniotic fluid through fetal urination, fetal gastrointestinal secretions, and transudation across fetal membranes (amnion and placenta) and immature epithelium. It is optimal to test MS between 16 and 18 weeks. Sagittal and transaxial images of the spine should demonstrate an intact dorsal skin line. Abstract Background. An elevated alpha fetoprotein (AFP) level in maternal serum and amniotic fluid is a reliable indicator of a fetal abnormality. It is important to note that the test only indicates that you are a greater or lower risk of giving birth to a child with birth defects. High levels of AFP can mean one of the following: Unusually low levels of AFP mean one of the following: There are certain factors that can influence the outcome of the test leading to results that can be misleading. AFP levels are normally elevated when a baby is born and then decline rapidly. Your individual circumstances and health will have to be taken into consideration before considering AFP values that are abnormally high. Elevated maternal serum alpha-fetoprotein (MSAFP) levels have been associated with an increased incidence of both placental sonolucencies and pregnancy complications. Elevated levels early in pregnancy may indicate a problem with the liver or bones and do need evaluation, although ALP levels alone are not diagnostic of any one disease since heart disorders, certain cancers, autoimmune diseases and gastrointestinal disorders can also cause a rise in ALP. Current guidelines recommend targeted screening of women at high risk, including those with a history of thyroid disease, type 1 diabetes mellitus, or other autoimmune disease; current or past use of thyroid therapy; or a family history of autoi… Pregnancy is associated with elevated AFP levels, particularly if the pregnancy is complicated by a spinal cord defect or other abnormality: Maternal serum AFP test results, interpreted according to the gestational age, are often reported in terms of multiple of the median (MoM). First, sonographic detection of the “likely” anomalies associated with high MS-AFP has improved over the last 10 to 15 years. AFP is reported as multiples of the median, so you want to be one. Impressively, of all anomalies detected in this program, nearly three quarters involved two organ systems: the neural axis (51%) and the ventral abdominal wall (21%). These include mosaic trisomy 8 and trisomy 9.31,2 For example, trisomies 13, 18, and 21 account for only 28% of abnormal karyotypes in women with high MS-AFP, compared with 75% of abnormal karyotypes in women ≥ of age. 8 Signs of a Multiple or Twin Pregnancy. In the fetus, serum AFP level increases until ~14 to 15 weeks and then falls progressively. The results are available in one or two weeks. AF-AFP testing is a highly sensitive method for detecting or excluding NTDs. Recall that most of the unsuspected autosomal trisomies detected with AFP screening will occur in the low MS-AFP group, and that autosomal trisomies represent the minority of abnormal karyotypes found in women with high MS-AFP. The AFP is excreted in the fetal urine which crosses into the mother’s bloodstream. Of those women whose tests show high or low levels of AFP, only two or three in 100 will have a child with a birth defect. High levels of AFP may also suggest defects with the esophagus or failure of your baby’s abdomen to close. However, high levels of AFP can also indicate that the mother is further along in her pregnancy than realized and her due date needs to be recalculated. However, almost 75% to 90% of babies with neural tube defects can be identified through this test; taking it might help you chart your future course of action. This is a blood test that tests for Alpha-Fetoprotein (AFP) level in the mother. Among women who choose to undergo amniocentesis following an “unrevealing” sono-gram, > 90% will have normal AF-AFP (< 2.0 MoM), and no further diagnostic evaluation is done.18 If the AF-AFP is elevated (≥ 2.0 MoM), then acetylcholinesterase (an isoenzyme important in neurotransmission) is tested on the amniotic fluid sample. Alpha-fetoprotein screening is a blood test that checks the level of alpha-fetoprotein in the mothers' blood during pregnancy. Nevertheless, there is a small, but important procedural fetal loss rate, 1/200 (0.5%), associated with amniocentesis. This test is almost accurate when done between 16 and 18 weeks of your pregnancy and looks primarily for birth defects in your unborn child. In men, non-pregnant women, and children, AFP in the blood can mean that certain types of cancer—especially cancer of the testicles, ovaries, stomach, pancreas, or liver—are present.High levels of AFP may also be found in Hodgkin's disease, lymphoma, brain tumours, and renal cell cancer. A normal AFP result cannot be taken as a guarantee that your pregnancy will be a normal one, or the baby born healthy. Unfortunately, this is impossible owing to considerable overlap in MS-AFP levels between normal and abnormal pregnancies. The level of alpha feto-protein starts to decrease soon after birth and is very low in normal adults i.e., less than 10 ng/ml (nanogram per milliliter). The intent of a standard antepartum obstetrical sonogram is to provide a general assessment of fetal/pregnancy health; it is performed according to the published guidelines endorsed by the American Institute of Ultrasound in Medicine (AIUM), ACOG, and American College of Radiology (ACR).15 The standard antepartum obstetrical sonogram is an important step in the triage of patients with high MS-AFP; impressively, approximately 20 to 50% of the elevated MS-AFP levels will be explained by findings on this preliminary sonogram (including the detection of a number of neural tube and abdominal wall defects).16,2 If the elevated MS-AFP is not explained by findings of the standard antepartum obstetrical sonogram, traditionally, the next step has been to counsel patients and offer amniocentesis for measurement of amniotic fluid (AF)-AFP. Sources of Maternal Serum–Alpha-Fetoprotein During a baby's development, some AFP passes through the placenta and into the mother's blood. Currently, over 300,000 pregnant women in California are tested annually. Twins - Ways to Confirm. These fetal deaths occur mainly in the second trimester, and the risk appears to be directly related to the degree of MS-AFP elevation.4 Insulin-dependent diabetes also influences AFP levels. However, it can also be useful for adults who arent pregnant. AF-AFP testing is a highly sensitive method for detecting or excluding NTDs. Normal. If the AF-AFP is elevated (≥ 2.0 MoM), a targeted fetal sonogram (level 2) is offered. Several other important fetal anomalies are associated with elevated AFP, and these potential defects should also be sought on the targeted sonogram (Table 17–1). A focused examination of the neural axis in each fetus should include an assessment of overall cranial size and contour, ventricular size (transaxial diameter of ventricular atrium > 10 mm is abnormal), and posterior fossa, including cerebellar morphology and cisterna magna.36–39 At the University of California–San Francisco, we also include images of the cavum septum pellucidum as a check for forebrain malformations. If MS-AFP is elevated, then a nontargeted, standard antepartum obstetrical sonogram (level 1) is performed for the purpose of identifying easily recognized causes of “false-positives” (gestational age ≥ 2 weeks more advanced than estimated clinically, multiple gestations, fetal death, and obvious fetal defects). The most commonly encountered individual defects are discussed in the following section. The baby might have an abdominal wall defect, a condition wherein the intestines or other organs are located outside the body. Liver cancer is also termed as ‘Silent Killer’ as the signs and symptoms of this disease do … A significant relationship was found between the high levels of maternal serum AFP and hCG MoM and poor pregnancy outcomes like preeclampsia, IUGR, PPROM, intrauterine fetal death (p=0.003, p=0.001, p=0.040, p=0.006). Some of the tests are done on a regular basis and recommended for all pregnant women, while others may be suggested based on individual factors such as the age of mother, medical history of parents or risk of genetic abnormalities. A number of tests may be suggested by your doctor during the course of your pregnancy. High AFP levels may indicate intrauterine death, or high levels indicate other anomalies, such as duodenal atresia, omphalocele, tetralogy of fallot, and Tuner’s syndrome. Stick the needle into the vein and draw blood till the tube attached to the needle is full. Should you have any concerns about your health, or of that of your baby or child, please consult with your doctor. 2004 Aug;22(3):227-34. doi: 10.1055/s-2004-831898. The information on this website is of a general nature and available for educational purposes only and should not be construed as a substitute for advice from a medical professional or health care provider. This test measures the level of AFP in your blood. Press a cotton ball over the needle site and apply a bandage over it. AFP levels can be categorized as normal, high, and low. It is a protein made in the liver of a developing baby. In most screening programs, karyotype testing is also routinely performed on the amniotic fluid specimen. AFP is a glycoprotein produced initially by the yolk sac and fetal gut, and later predominantly by the fetal liver. High levels of AFP can mean one of the following: You are carrying more than one baby. Researchers opine that lower the MoM value of PAPP-A, higher are the risks of poor pregnancy results. In normal pregnancies, AFP from fetal serum enters the amniotic fluid through fetal urination, fetal gastrointestinal secretions, and transudation across fetal membranes (amnion and placenta) and immature epithelium. High levels of AFP may suggest the developing baby has a neural tube defect such as spina bifida or anencephaly. Most screening programs in the United States have settled on a serum value of ≥ 2.5 MoM. At the end of the first trimester, it is present in the fetal serum in milligram quantities, and in the amniotic fluid in microgram quantities, and in the maternal serum in quantities measured in nanograms. Abnormal levels of AFP can indicate several problems. The fetus has omphalocele complications. High levels of AFP may suggest the developing baby has a neural tube defect such as spina bifida or anencephaly. Some favor a paradigm in which targeted sonography follows a high MS-AFP, arguing that there is only a very small risk of an abnormal karyotype in a fetus without morphological defects. It is estimated that as many as 20 to 38% of women with unexplained high MS-AFP will suffer adverse pregnancy outcomes9,2; this information is another important benefit of MS-AFP screening. 2.6 is 2.6 times the average amount. Recall that most of the unsuspected autosomal trisomies detected with AFP screening will occur in the low MS-AFP group, and that autosomal trisomies represent the minority of abnormal karyotypes found in women with high MS-AFP. It is critical that this be diagnosed accurately because most patients will electively terminate their pregnancies following this diagnosis. You might feel a pinch or a sting at the most, when the needle pierces your arm. Amniotic fluid volume should be qualitatively or semiquantitatively assessed in addition to careful examination of the placenta. Some have cautioned against adopting a routine policy of circumventing the amniocentesis because (1) this approach will require a much larger number of targeted sonograms (i.e., 10 times as many), and the larger number of experienced examiners may not be available, or patients may be required to travel a long distance for the targeted sonogram; (2) even experienced examiners, especially as the prevalence of defects falls in the population scanned, may not detect as many defects as AF-AFP testing; and (3) skipping amniocentesis will cause potentially detectable chromosomal abnormalities to be missed.23,2 The last issue remains controversial, and multicenter consensus has not been reached. Its usually part of whats called a triple screen or quad screen in the second trimester of pregnancy. The AFP gene is located on the q arm of chromosome 4 (4q25). Increased levels … Parenting.Firstcry.com accepts no liability for any errors, omissions or misrepresentations. Acetylcholinesterase is present in association with exposed neural tissue (and occasionally with abdominal wall defects). In most screening programs, karyotype testing is also routinely performed on the amniotic fluid specimen. The level of AFP in the mother’s blood tends to be elevated when there is a pregnancy affected by a neural tube defect. The targeted sonogram is performed to determine (1) whether any fetal anomaly is present (AFAFP may be false-positive); (2) if the fetus is abnormal, what the nature of the anomaly is (e.g., NTD versus omphalocele); and (3) if present, the severity of the anomaly and presence/absence of associated malformations (e.g., spinal level of myelomeningocele). AFP is a substance made in the liver of a developing baby (fetus). Ultrasound Evaluation Serum AFP levels were recorded in multiples of the median value (MOM) calculated from normal singleton pregnancies. AFP goes through the placenta into the mother's blood. Several other important fetal anomalies are associated with elevated AFP, and these potential defects should also be sought on the targeted sonogram (Table 17–1). Two procedures available during pregnancy may help identify problems associated with elevated AFP levels. Pregnant women with PAPP-A level lower than 0.5 MoM need constant monitoring as they are believed to be at a higher risk of having premature labour, intrauterine growth restriction, pregnancy-induced hypertension and a miscarriage. In normal pregnancies, AFP from fetal serum enters the amniotic fluid through fetal urination, fetal gastrointestinal secretions, and transudation across fetal membranes (amnion and placenta) and immature epithelium. It would be ideal if a single MS-AFP level could completely segregate normal from abnormal fetuses. Diagnostic aid in premature rupture of membranes (PROM) A study looking at prolactin, AFP and beta human chorionic gonadotrophin (beta-hCG) in vaginal fluid as markers for diagnosing PROM , showed that AFP had the greatest accuracy (94% sensitivity and specificity). In the fetus, serum AFP level increases until ~14 to 15 weeks and then falls progressively. The normal values listed here—called a reference range—are just a guide. Maternal serum AFP is usually high in multiple gestations and is normally higher than the overall population average in some ethnic groups. AFP stands for alpha-fetoprotein. If your AFP results show abnormal levels, discuss this with your doctor, or you may be referred to a genetic counsellor. Using this cutoff, ~90% of anencephalic fetuses, 75 to 80% of fetuses with an open spinal defect, 98% of fetuses with gastroschisis, and ~70% of fetuses with omphaloceles will be detected.11 Further, using 2.5 MoM as the cutoff has resulted in a reasonably low screen-positive rate (~4 to 5%). Indeed, the United Kingdom has adopted this paradigm and detailed, targeted sonograms are now routinely performed as the second diagnostic step in women with high MS-AFP. Levels of AFP are usually normal in the amniotic fluid of a majority of women who have abnormal AFP blood levels. Maternal AFP serum level is used to screen for Down syndrome, neural tube defects, and other chromosomal abnormalities. You are a smoker, which can cause higher levels of AFP in the blood. An AFP test screens for abnormal levels of AFP. Expected rates of sonographic detection for neural tube and abdominal wall defects are currently > 90%.21–27 It is estimated that a complete, detailed, normal sonogram can now reduce the MSAFP-based risk of a neural tube or ventral abdominal wall defect by 95%.28,2 Second, going directly to a targeted sono-gram circumvents the small, but important procedural risk of fetal loss from amniocentesis. About 90 percent of all pregnancies with open neural tube defects will be identified through AFP PLUS testing. A focused examination of the neural axis in each fetus should include an assessment of overall cranial size and contour, ventricular size (transaxial diameter of ventricular atrium > 10 mm is abnormal), and posterior fossa, including cerebellar morphology and cisterna magna.36–39 At the University of California–San Francisco, we also include images of the cavum septum pellucidum as a check for forebrain malformations. Remove the elastic band from your arm after blood has been drawn. Accurate sonographic diagnosis has become extremely important in light of AFP screening in pregnancy. Diseases such as mononucleosis and cytomegalovirus, which can be harmful to a fetus, can also cause rises in A… Hidden Twins. During pregnancy, AFP tests may be done to find or watch defects in the developing fetus. An AFP test helps your doctor decide if further tests or screenings are required during your pregnancy. The intent of a standard antepartum obstetrical sonogram is to provide a general assessment of fetal/pregnancy health; it is performed according to the published guidelines endorsed by the American Institute of Ultrasound in Medicine (AIUM), ACOG, and American College of Radiology (ACR).15 The standard antepartum obstetrical sonogram is an important step in the triage of patients with high MS-AFP; impressively, approximately 20 to 50% of the elevated MS-AFP levels will be explained by findings on this preliminary sonogram (including the detection of a number of neural tube and abdominal wall defects).16,2 If the elevated MS-AFP is not explained by findings of the standard antepartum obstetrical sonogram, traditionally, the next step has been to counsel patients and offer amniocentesis for measurement of amniotic fluid (AF)-AFP. Among fetal defects, the most common mechanism is through fetal cutaneous defects. An elevated AFP level may be indicative of one of three things: The mother is farther along in pregnancy than she thought. However, the most common reason for elevated AFP levels is inaccurate dating of the pregnancy. One should be cautious, however, not to confuse an engaged fetal head (in which the convexity may not be well visualized) for anencephaly. The spine should be carefully examined in each fetus, including segment by segment images in the transaxial and sagittal planes from the craniocervical junction through the sacrum. When we went to the fetal specialist the doctor told us spinal bifida is usually in the 7's for the AFP levels. These two groups of fetal defects (and many others) can now be accurately detected on targeted prenatal sonograms performed by experienced examiners. Surgery after birth can help rectify this. The normal curvature of the spine should be documented, and the ossified posterior elements examined for abnormal splaying. Thus, the choice of a judicious cutoff value that maximizes detection of anomalies and minimizes the number of false-positive results is necessary for this screening program to be effective. While the exact function of AFP is unknown, it is made by the fetal liver, and the level of AFP rises and falls at specific times in the pregnancy. High levels of AFP can indicate an increased chance of the fetus having a neural tube defect such as spina bifida. As a result, women with elevated MS-AFP have, in increasing numbers, opted to go directly from the serum AFP test to a targeted fetal sonogram, skipping the amniocentesis. High AFP could mean you're further along than you thought, because your level keeps going up throughout your pregnancy. A myelomeningocele is suggested by a defect in the normal smooth dorsal skin line and splayed posterior ossification centers on the transaxial image (Fig. © 2010-2020 Parenting.FirstCry.com. There are several potential ways that fetal AFP can enter the MS in abnormal quantities. Normal values will also depend on the age of the baby. Any abnormal AFP results will be followed up by repeat AFP testing, and if the results are the same, an, If an ultrasound does not reveal the reason behind unusual AFP levels, an invasive test such as. High levels of AFP may also suggest defects with the esophagus or failure of your baby’s abdomen to close. This distinction is accomplished by the observation of amniotic fluid above the orbits and the calvarial defect. Most screening programs in the United States have settled on a serum value of ≥ 2.5 MoM. However, the level of AFP may increase in adults, in the following cases: During pregnancy; Liver diseases such as hepatitis and cirrhosis The normal curvature of the spine should be documented, and the ossified posterior elements examined for abnormal splaying. Higher than normal AFP levels in the blood of the mother may mean: The baby's brain is not developing (neural tube defects). Healthy adults should have very low levels of AFP. But when you have liver disease, some types of cancer, or are pregnant, you'll usually have more of it … AFP goes through the placenta into the mother's blood. A neural tube defect is an abnormal fetal brain or spinal cord that is caused by folic acid deficiency during pregnancy. may not detect as many defects as AF-AFP testing; and (3) skipping amniocentesis will cause potentially detectable chromosomal abnormalities to be missed. The most commonly encountered individual defects are discussed in the following section. Men, non-pregnant women, and children. Normal cerebral cortex is absent. A positive test with a high AFP suggests a birth defect like spina bifida. Usually, you have a very small amount of alpha-fetoprotein (AFP) in your body. As the baby grows and produces more AFP, the amount in the mother's blood increases.Between weeks 15 and 20 of a pregnancy, a maternal serum alpha-fetoprotein (MSAFP) screen may be offered. The latter group is discussed elsewhere. normal afp levels in pregnancy A 40-year-old female asked: i spoke with a researcher at ucla in 1989 who had followed 60, 000 pregnancies, elevated afp levels, and outcomes. The screen doesnt even flag as abnormal until you hit 2.5 so you are just above that. Levels of aFP can also be slightly elevated (up to 500 μg/L) in pregnancy, reflecting fetal production, or sometimes higher in several obstetric complications. MOMS are typically corrected for maternal weight, race, and diabetes. Too much or too little AFP in a mother's blood may be sign of a birth defect or other condition. Screening for AFP levels is usually done at the beginning of the second trimester, between your 15th and 17th week of pregnancy, due to the fact that a dramatic increase in AFP occurs between the 4th and 6th month of pregnancy. Elevated alkaline phosphatase levels of two to four times normal late in pregnancy are not a reason for concern. The ventral abdominal wall of the fetus is examined, with focused attention on the umbilical cord insertion. In one study, either high or low MSAFP was associated with 34% of all major congenital defects.2 Further, even in the absence of multiple gestations and discrete fetal defects, earlier studies suggested that women with high MS-AFP had a much higher rate of adverse pregnancy outcomes.3,2 More recent publications indicate that this association holds true for fetal death and premature birth, but an elevated AFP may not be a risk factor for fetal growth restriction and preeclampsia.5–8 An alpha-fetoprotein (AFP) test is a blood test that measures the amount of AFP present in blood. The level of AFP in your bloodstream increases substantially in the fourth to sixth months of pregnancy, so if you have a high result it may indicate that your pregnancy is further advanced than you realised and your due date needs to be calculated again. Maternal Serum–Alpha-Fetoprotein Screening An AFP test measures the level of AFP in pregnant women during the second trimester of pregnancy. The normal range of AFP values can vary somewhat, depending on the lab you go to. Roughly 6 to 15% of women with high MS-AFP have some type of major congenital defect, and this risk increases with the magnitude of MS-AFP elevation.2,13,14. Thus, the choice of a judicious cutoff value that maximizes detection of anomalies and minimizes the number of false-positive results is necessary for this screening program to be effective. Roughly 6 to 15% of women with high MS-AFP have some type of major congenital defect, and this risk increases with the magnitude of MS-AFP elevation.2,13,14 Examples of these birth defects include spina bifida and anencephaly. AFP levels are usually high when a baby is born, but fall to very low levels by the age of 1. The baby may have physical defects such as dwarfism (DWORF-izm). Unfortunately, this is impossible owing to considerable overlap in MS-AFP levels between normal and abnormal pregnancies. Minor discomforts such as those associated with a regular blood test might occur. You also acknowledge that owing to the limited nature of communication possible on interactive elements on the site, any assistance, or response you receive is provided by the author alone. AFP is present in the fluid around the fetus (amniotic fluid) and a small amount crosses the placenta and moves into the mother's blood stream. There are almost no risks associated with an AFP test. These included 710 NTDs (417 anencephaly, 247 spina bifida, and 46 encephalocele), 286 ventral abdominal wall defects, 163 fetuses with Down syndrome, and 231 cases of other chromosomal anomalies. Further, fetuses with autosomal trisomies 13, 18, 21 detected as a result of high MS-AFP often have sonographically detectable structural abnormalities.25,2 If the targeted sonographic fetal survey in a woman with elevated MS-AFP is normal, it has been estimated that the risk of a fetal chromosomal abnormality is only 0.6 to 1.1%, and sex chromosome aberrations (other than 45X) account for many (30 to 50%) of the chromosomal abnormalities in these fetuses.24–28 Some reasons why you might be asked to get an AFP test are: No preparation is required before you get the AFP test. There is an Afro‐Caribbean effect on serum AFP, which is dependent on gestational age, whereby relative serum AFP levels are high at early gestations and low at late gestations. Disclaimer: This information is just a guide, and is not a substitute for medical advice from a qualified professional. HCG Levels Twins Chart: [40% Higher]. Soreness or pain at the spot where the needle was inserted. Thyroid disease is the second most common endocrine disorder affecting women of reproductive age, and when untreated during pregnancy is associated with an increased risk of miscarriage, placental abruption, hypertensive disorders, and growth restriction. These fetal deaths occur mainly in the second trimester, and the risk appears to be directly related to the degree of MS-AFP elevation.4. Ultrasound (sonogram) is a tool used to date the pregnancy and look carefully at the bones and internal organs of the baby. First, sonographic detection of the “likely” anomalies associated with high MS-AFP has improved over the last 10 to 15 years. Detectable quantities of AFP in the MS gradually increase during gestation, peaking at 30 to 32 weeks and declining thereafter. A high AFP could also mean the mother is carrying twins, according to Kaiser Permanente. Wrap an elastic band around the intended spot, usually on the upper arm, so that the vein is easy to find. The following are commonly thought to be in the alpha-fetoprotein normal range. During pregnancy, AFP tests may be done to find or watch defects in the developing fetus. Alpha-fetoprotein is a major protein produced by the fetal yolk sac, a part … Maternal Serum Screening Test Positive for Down Syndrome, ULTRASOUND EVALUATION OF MULTIPLE PREGNANCIES, THE PRENATAL MANAGEMENT OF THE FETUS WITH A CORRECTABLE DEFECT, Ultrasonography in Obstetrics and Gynecology. These two groups of fetal defects (and many others) can now be accurately detected on targeted prenatal sonograms performed by experienced examiners. In non-pregnant adults (males and females) the high value of Alpha-FetoProtein indicates the danger of cancers related to testicles, … During a baby's development, some AFP passes through the placenta and into the mother's blood. Are you homeschooling your child, or want to further support your child’s education at home? The fetus has a neural tube defect. MS-AFP values are also corrected for maternal age, maternal weight, race, and the presence of diabetes (diabetes has a depressing effect on MS-AFP, so lower levels may be found in association with NTDs).12 In California, ~2% of screened women have elevated MS-AFP levels (≥ 2.5 MoM), and ~3% have MS-AFP levels ≤ 0.5 MoM.
