Depends: If the exposure is within a couple of weeks, IgM would be the test to get. On the other hand, there is no harm if getting IgG which would indicate exposure months or years ago. Unfortunately an infected person, even in the absence of symptoms,may infect other people. Until this situation has been settled, insist on condom use.
