Can herpes culture test be false positive? If so, now often?

Unlikely. A false positive result would be extremely unusual. It would require either laboratory contamination or a clerical or technician error in which the result was reported for the wrong patient. I trust herpes culture results.

Is it possible to get a false positive herpes culture test? How often does it occur? What is the reasoning for it?

Rarely if ever. False positive results are very unlikely for HSV culture. If the test was actually a DNA test (PCR test), there is a slightly higher chance of false pos, but still very unlikely. If you have had a positive culture or PCR, for sure you have herpes at whatever site was tested (genital, oral). But if a blood antibody test, not culture or PCR, false positive results are quite common. Good luck. Read more...
