PCR rules out HIV infection

Hi
Welcome to Healthcare-Magic
Greetings of the day
Dear Mr XXXXXXX

HIV PCR done 2 weeks after potential exposure rules out the probability of having contracted HIV infection.
Spot test is not confirmatory. As you have got the test on 36th day , it rules out HIV infection.

Do get back to me if you need any further assistance, will be glad to assist you.

Take care

Hi

Dna PCR relies on direct detection of virus particles unlike other test which rely on development of antibodies against the virus which may take 90 days top form.
Negative PCR test as early as 10 days rules out infection. As your test is done 36 days following exposure it completely rules out HIV infection.

Take care
