Maternal serum alpha fetoprotein concentrations in mid trimester in hepatitis B surface antigen positive and negative subjects.
Abstract
Maternal serum alpha fetoprotein (AFP) was measured as part of a routine antenatal screening programme in 48 patients positive for hepatitis B surface antigen (HBsAg). After exclusion of two cases with obvious obstetric abnormalities there was no difference in AFP concentrations between subjects who were positive or negative for HBsAg.
