Respond Tatyana Stepanova, a gastroenterologist, hepatologist presence of HBsAg can mean the carrier or chronic hepatitis B. It is necessary to further tests: blood chemistry: ALT, AST, GGT, bilirubin, alkaline phosphatase, a blood test for hepatitis B virus DNA Only the results of all tests can properly diagnose. And sometimes we have to do a liver puncture, which would decide on further management of the patient. Naturally, the puncture is contraindicated in pregnancy. If you notice only HBsAg, without the presence of other markers of hepatitis B virus, the probability of intrauterine transmission of infant 5 - 15%. If there are other markers that indicate replication of the virus, the chances of catching the baby grows. After the birth of a child will need to be vaccinated against Hepatitis B and introduce him to immunoglobulin. In the case of infecting the baby during delivery, the combined effect of vaccination and the vaccine will prevent disease progression. If an infant infected in utero, then the vaccine and the vaccine will help prevent the disease. Similar question: ... please, what is meant by analysis?
