Elevated alpha-fetoprotein
Maternal testing for fetal screening

Because MSAFP test results must be interpreted according to the gestational age, they often are reported in terms of multiple of the median (MoM). Because the median is calculated from tests of other women's pregnancies at the same gestational age, in effect MoM is independent of gestational age, but depend on accurate gestational dating. A typical normal range is 0.5 to 2.0 or 2.5 MoM.
