Had a pcr test for mycoplasma genitalium and it came back saying uninhibitory so had to re do it. what does that mean?

Neutral: It means the result was indeterminate, cannot tell whether or not M. genitalium is present. It doesn't lean one way or the other -- it's as if you had not been tested at all. But if you're the person who has been asking repeatedly about prostatitis, this result doesn't matter. M gen is not known to cause prostatitis. Whether negative or positive, it won't solve that diagnosis.
