Am 32 years male I did unprotected sex with one lady so many times( more then 100 times) later on I identified that she is hiv positive. Then after my last exposer I went western blot on 84th day, tridot on 120th day, ELISA on 135th day all are came negative. Is it enough to rule out hiv? Is any other test is required? Window period is 3 months or 6 months? please help me.

Hello,

Thank you for your inquiry. From what we gather from the question, you are asking about the conclusivity of the Western Blot, TRI-DOT, and ELISA tests, taken at specified dates post-exposure.

The Western Blot Test is considered to be the "gold standard" of HIV testing, and is considered accurate at 8 weeks post exposure, so taking the test at 84 days (12 weeks) would be considered an accurate result.

The ELISA test (third generation) accuracy approaches 100 percent for diagnosing chronic infection, and can be used any time after 3 weeks, so testing at 135 days (19 weeks) would be considered an accurate result.

With both of these tests taken, and both yielding a negative (non-reactive) result, these results would generally be considered conclusive. If you still have concerns, please speak to your physician.

Thank you, and good luck!
