briefly :(after exposure)
- since day 21: had very painful and slightly swollen armpits, chest and groins lymph nodes
- since day 46: had all HIV symptoms like chronic fever, sore throat, joint and muscle pain, bruises, fatigue, white coated tongue
- a negative PCR by day 31
- negative 4th gen ELISA at days 24, 40, 53, 60, 69 and ELFA by day 73
virologist is confused seems there is no other condition with all HIV symptoms together
what should I do now?
Thank you for your inquiry. From what we gather from the question, you were asking about the accuracy of multiple 4th generation HIV tests you received, with the most recent being performed at 73 days (10.5 weeks) after your potential exposure.
Fourth-generation HIV tests can detect HIV infection in 50% of people by 18 days after infection; 95% of people by 34 days after infection; and 99% of people by one and a half months after infection. Fourth-generation HIV tests and the INSTI rapid test have a sensitivity of about 99.9%. Since the vast majority of people who get tested for HIV are actually HIV negative, the chance of a negative result being false is extremely low.(1)
Since four of your six tests were performed beyond the one and a half month window period, you can certainly consider your negative result conclusive for this exposure.
It is impossible to attribute your symptoms to an HIV infection in the absence of a positive HIV test result. We would recommend that you continue to investigate other causes for your symptoms with your doctor.
