You know, the IgM isn’t wrong every time, and it is particularly false positives that are the problem. But I still wouldn’t rely upon it.
You need 16 weeks for a reliable test result from the time of any concerning sexual exposure.
Valtrex can impact the testing if taken for a longer period of time than 10 days. I would just recommend that you not take any more until you’ve done your final test so you never have to wonder if your test result is correct or not.
