HIV test while on prep

[Temptationwaits]

Hi. 

Does being on prep affect hiv tests? Just wondering if if might suppress levels of the virus to the extent you could get a false negative result.

In the latest case of PrEP seroconversion, the guy kept testing negative on his 3rd gen HIV antibody testing while his PCR was +. 4th gen eventually became poz. 

So yes, it does seem like PrEP may delay a poz on antibody tests, specially older 3rd generation. Ask your provider to do regular PCR or 4th gen to catch anything asap.
