Good Morning
I have put myself at risk with mutual oral sex with a CSW in Singapore.
I have since done a full 14 day STI screen with a reputable test center in the UK and all results have all came back negative but after checking online (bad mistake) I am now quite anxious regarding the accuracy of the HIV PCR RNA test as lots of people say this is not conclusive and I need to test at 28 days and 3 months, while others say this is conclusive at over 99% accurate at 14 days.
I have seen this test is used in the UK by the blood transfusion and organ donor services checking for HIV as well.
Can you tell me how accurate/conclusive this negative result and why it is not deemed conclusive if it is indeed very accurate and used for checking blood transfusion and organ donors
