I know that questions regarding the window period have been asked repeatedly on this forum, but I haven't found a clear answer/discussion yet in my search. Some posts do discuss the issue but they were posted 2-3 years ago so I am not sure if they are still as valid as they were then. My question is:
At how many weeks after a possible exposure a negative HbsAg test can be considered conclusive?
I had two possible exposures (needle stick) and I have tested several times since then. So far every report has come back negative. My latest test was done at 9 weeks mark from the first exposure and 6 weeks mark from the second one.
Thanks for your reply cajim. I was wondering if there was a test that could determine the absence/presence of the virus much earlier than that. For example, for HCV there is RNA (PCR) test. Can HBV DNA test do that?
