Perinatal Transmission
Hepatitis B virus (HBV) infection in a pregnant woman poses a serious risk to her infant at birth. Without postexposure immunoprophylaxis, approximately 40% of infants born to HBV-infected mothers in the United States will develop chronic HBV infection, approximately one-fourth of whom will eventually die from chronic liver disease.
Perinatal HBV transmission can be prevented by identifying HBV-infected (i.e., hepatitis B surface antigen [HBsAg]-positive) pregnant women and providing hepatitis B immune globulin and hepatitis B vaccine to their infants within 12 hours of birth.
Preventing perinatal HBV transmission is an integral part of the national strategy to eliminate hepatitis B in the United States. National guidelines call for the following:
- Universal screening of pregnant persons for HBsAg during each pregnancy
- HBV DNA testing for HBsAg-positive pregnant persons at 26-28 weeks to guide the use of maternal antiviral therapy during pregnancy. AASLD suggests maternal antiviral therapy when HBV DNA is >200,000 IU/mL
- Case management of HBsAg-positive mothers and their infants
- Provision of immunoprophylaxis for infants born to infected mothers, including hepatitis B vaccine and hepatitis B immune globulin within 12 hours of birth
- Routine vaccination of all infants with the hepatitis B vaccine series, with the first dose administered within 24 hours of birth

This page describes the four most common tests used in hepatitis B serologic testing and provides guidance to interpret different patterns of test results.
This is a clinical algorithm for screening and referral of pregnant women who are HBsAg-positive.

This document describes management of infants born to HBV-infected persons, guidance on interpreting post vaccination serologic testing (PVST) results, and frequently asked questions.
Ordering Prenatal Hepatitis B Surface Antigen (HBsAg) Tests from Major Commercial Laboratories
All pregnant women should be tested for HBsAg during an early prenatal visit in each pregnancy, and all HBsAg-positive pregnant women should be tested for HBV DNA to guide the use of maternal antiviral therapy during pregnancy.

*This CPT code corresponds only to the HBsAg screening component; additional CPT codes might be associated with other component tests.
Notes: CDC recommends healthcare providers use prenatal HBsAg tests (vs. non-specific tests) for pregnant women, which allows for reporting of positive results along with pregnancy status to public health jurisdictions. Refer all HBsAg positive pregnant women to Perinatal Hepatitis B Prevention Program coordinators for case management of mother and infant: https://www.cdc.gov/vaccines/vpd/hepb/hcp/perinatal-contacts.html.
Laboratories reserve the right to add, modify, or stop performing tests at any time – providers should review any test notifications from laboratories for changes.
