Alpha-fetoprotein (AFP) Blood test to check AFP levels in a pregnant woman’s blood. AFP is a substance produced in the liver of an unborn baby (fetus). The amount of AFP in the blood of pregnant women can help to understand whether the baby may have problems such as spina bifida and anencephaly.

How do you calculate AFP MoM?

For example, the alpha-fetoprotein (AFP) test is used to screen for neural tube defects (NTD) in the second trimester.If the median AFP result at 16 weeks of gestation is 30 ng/mL and the AFP result for a pregnant woman of the same gestational age is 60 ng/mL, then her MoM is equal to 60/30 = 2.0.

What is carcinoembryonic antigen level?

Carcinoembryonic Antigen (CEA) Test Measures CEA levels in the blood. CEA is a protein that is normally present in the tissue of a developing baby in the womb. Blood levels of this protein disappear or become very low after birth. In adults, abnormal CEA levels can be a sign of cancer.

What can cause low AFP levels?
