Prevention of Mother-to-Child (Perinatal) Transmission of Hepatitis B

You answered:

D Check her serum for antibody to hepatitis B e antigen (anti-HBe).

This answer is incorrect. Although it is reasonable to check for evidence of prior HBV and immunity to HBV, the preferred screening test for that purpose would be antibody to hepatitis B surface antigen (anti-HBsAg), not anti-HBe.  The hepatitis B surface antigen (HBsAg) test is the preferred screening test to determine whether the mother is at risk of transmitting HBV to her child.

Choose another answer:

A No testing for hepatitis B is indicated since it is highly likely that she received hepatitis B vaccine as a child or as an adolescent.
B No testing for hepatitis B is indicated; begin a three dose series of hepatitis B vaccine.
C Check her serum for hepatitis B surface antigen (HBsAg).
