Question for the forum. I did a Anitbodies Blood Test 1/2 about 4 years ago. It was for a exposure of vaginal sex (I’m male) unprotected 4 years I took the test. Came out non-reactive. I was relief and since then, absent of sex. Will my test be conclusive/would that test be accurate after 4 years? I’m asking because I’ve had rashes and my tongue is white...should these worry me?
