ORAL THRUSH AND ULCERS ON TONGUE

Question: 

Good evening,
Please help. i had unprotected sex with sex worker. Did an hiv rapid determine antibody test 6 weeks 5 days after PEP completion (10 weeks 5 days post exposure) which came back negative. But am worried of the oral thrush and ulcers on my tongue. Could this be seroconversion? Can i rely on my negative test results?

Answer: 

Hi there,

Thank you for your inquiry. From what we gather from the question, you were asking about the reliability of your negative test results received 6 weeks, 5 days after PEP completion.

The Rapid "point of care" testing method is considered highly accurate, at a rate of 99.9% (1). The testing window period for this test is between 4 weeks and 3 months (although 95% of infections are detectable between 4-6 weeks). Although official HIV testing guidelines recommend re-testing at 12 weeks for completely conclusive results, the reliability of your negative results stand.

While the thrush and ulcers on your tongue may signify a decreased immune function, it is nearly impossible to attribute these symptoms to seroconversion without adequate testing confirmation.

Recommendation: Please seek HIV testing at the recommended (3 months and 6 months) post PEP completion for completely conclusive results, and seek out a physician for any additional medical concerns you have concerning your oral thrush and ulcers.

All the best,
