I am planning to take HBV DNA test after a recent exposure.(3 months ago). I took multiple hbsag tests and all are negative till this point. most of the experts here say that the test window is 6 months. I cannot wait for another 3 months.the wait is killing me. Is it worth taking the HBV DNA test and put the entire thing to rest. also If i take the vaccine now will it have any impact on DNA test.
