- HBsAg at booking. If positive: HBV DNA (or HBeAg if DNA is not available), LFTs, refer to hepatology.
- Tenofovir (TDF) 300 mg daily from 28 weeks to at least birth if HBV DNA 200,000 IU/ml or more, or HBeAg-positive where DNA is unavailable.
- Baby: hepatitis B vaccine within 24 hours of birth, then the routine schedule.
- HBIG within 24 hours for high-infectivity mothers (HBeAg-positive, very high DNA, acute infection).
- Breastfeeding is fine; CS is not needed for hepatitis B.
WHO 2024 also allows tenofovir for all HBsAg-positive pregnant women where DNA and HBeAg testing are unavailable.
