I had a protected sexual encounter with a sex worker in Turkey.I had gone through fourth generation Duo Ultra tests after 15 25 30 42 days, Hiv1 RNA PCR after 15 days, Than i had combo test after 35, 56, 63 and 72 days and values for all the tests came back as negative.Do i need more tests as i had taken all the tests at appropriate times.
Thank you for your inquiry. From what we gather from the question, you were asking about the conclusiveness of the negative test results you received at 35, 56, 63 and 72 days post exposure.
Official HIV testing guidelines recommend re-testing at 12 weeks (84 days) post exposure for completely conclusive results. However, please consider that the combo test is specifically designed to detect both P24 antigen and HIV antibodies, and that most specialists consider these results conclusive at 6 weeks (42 days) post exposure. For this reason, you may consider this exposure to leave you with an HIV negative status.
Recommendation: No need for HIV testing, please refer to health care provider for additional questions.
All the best,
