title: Hepatitis Bs antigen (HBsAg) during pregnancy.
abstract: Three patients with serum hepatitis during pregnancy are described. The first patient was delivered of an infant in whom hepatitis B surface antigen (HBsAg) was detected at 3 months of age; the second patient had a child who became HBsAg positive at 6 weeks of age; and the third patient's child (recently delivered) was negative for HBsAg at birth. Suggestions for the management of this unusual complication of pregnancy are made.
