PCR tests cannot give conclusive test results.

Which one is more reliable Teak? Surely a PCR detects the virus where as an antibody detects response ? Why is an antibody considered conclusive?

The antibody test at 3 months post exposure.

A p24combo is excellent at 4 weeks,followed up by an antibody test at 3 Months.The HIV RNA by PCR is good for early detection but is not a stand alone test.

What is the science behind that? I thought looking for something directly would be easier than looking for a reaction to something? Thanks for the response.

That question was already answered;
PCR tests cannot give conclusive test results

A negative antibody test at 3 months is conclusive.

So you would take a neg 3 month antibody over a neg PCR? In terms of accuracy & reliability?
