I am afraid that contracted by a man who suffered from hepatitis B + D. But he said he did recently in February assays (ELISA) and are HBsAg negative, but there are antibodies to hepatitis B and hepatitis D That is all that it is only positive antibodies. Questions: 1) This person is contagious? OR WITHOUT PCR nothing is impossible to talk 2) states that the HBs ag may then appear, then disappear.
