Alpha-Fetoprotein (AFP, SAFP)
|
Alpha-fetoprotein (AFP) is the major protein found in fetal serum,
similar in size and several other characteristics to albumin in adult blood.
AFP is not normally present in adult blood.
During pregnancy, even though the maternal and fetal blood streams are
separate, small amounts of AFP leak into the maternal system, the amount
varying with the gestational age.
If unusually large amounts of AFP are found in the maternal blood stream
(>2.5 MOM or Multiples of the Mean), this may indicate:
- Fetal neural tube defect, such as spina bifida, anencephaly, or
encephalocele
- Malformation of the fetal GI tract
- Malformation of the fetal abdominal wall
- Normal twin pregnancy
