Hello and welcome to e health forum.

Yes, you can rely on the HIV PCR results.

Polymerase chain reaction (PCR) for proviral DNA (PCR -DNA) is a important test that can detect ‎proviral DNA during window period, can differentiate latent HIV infection from active viral transcription ‎and can quantitate the copy number of HIV DNA when used with external standards (e.g. viral load ‎assays). The DNA PCR is the absolute most sensitive test for HIV.
‎
For proper and valid results, it is recommended to take this test after 2 weeks of a suspected ‎exposure. Since you underwent the test after 20 days, the test results are very reliable.

Your sorethroat is possibly due to bacterial pharyngitis, which may need treatment with antibiotics. Hence you may consult your doctor for a examination and proper advice.

I hope this helps.
