Alpha Feto Protein (AFP) is a protein made in the liver of a fetus, and the amount of it in a pregnant woman blood can help to see whether the fetus may have such problems as spina bifida, anencephaly, and omphalocele (Ball et al.
, 1992). Also, AFP level in the serum of pregnant woman’s blood can be checked to find chromosomal problems, such as Down syndrome (trisomy 21) or Edwards syndrome (trisomy 18) (Muller et al., 2003).
In adults, AFP is considered as a tumor marker to help detect and diagnose cancers of the liver (Otsuru et al., 1988). The AFP level is often ordered to monitor in people with chronic liver dis- eases such as cirrhosis, chronic hepatitis B or hepatitis C.
