I've read various articles and posts claiming that PCR tests are not considered reliable after a certain amount of time. I asked my doctor for one nine weeks after a potential oral exposure (with no ejaculation) that came back negative.
I would like to know if that test is considered reliable. Also, are standard ELISA tests normally administered in hospital labs when PCR tests are requested?
I understand what this website's stance is regarding HIV and oral exposures. My question more so pertains to the PCR test itself.
Thanks in advance for your response.
