HIV Test Window Period?

What are the chances that the results from an HIV test taken a month after possible infection are accurate? I know that a test is usually the most accurate 3-6 months or even a year after possible infection. I plan on getting tested again, but I'm terrified that the results will differ from those of my first test, in which I tested negative.

It takes at least 30 days (in rare cases 3 months and in even rarer cases 6 months) for the HIV virus to show up on the test. I would say test after that 30 days and again after the 6 month mark to ensure 100% accuracy. Remember, any unprotected sexual activity during that time start the timeline over if you are looking for 100% accuracy.

it takes a minimum of 6 months for an HIV test to show accurately

Hi, there.

75% of people will seroconvert (create antibodies to HIV and therefore test positive with an HIV Antibody Test) by 17-20 days.
95% will do the same by 2months
99% will do the same by 12-13 weeks.

The balance may take longer if there is already a compromised or dysfunctional immune system that cannot create antibodies as well or at all. Eg. chemo/radiation, transplant recipients, anyone taking large doses of steroids.

Hope this helps

You have to have the second test to be sure.
