What tests are needed if pregnant with hepatitis B "big three positives"?

Pregnant women with positive "big three" markers for hepatitis B should undergo a series of examinations during pregnancy to ensure maternal and fetal health. Liver function tests are essential to monitor the liver's metabolic and detoxification capacity. Quantitative detection of hepatitis B virus (HBV) DNA helps assess the level of viral replication and infectiousness. Additionally, abdominal ultrasound or color Doppler ultrasound can be used to evaluate the liver's morphology, size, and presence of space-occupying lesions, thus determining the extent of liver damage. In late pregnancy, liver reserve function tests are also required to assess the liver's ability to tolerate the physiological demands of pregnancy. Pregnant women should also have regular prenatal check-ups to monitor fetal growth and development. If HBV levels are excessively high, timely antiviral therapy may be necessary.
