Do you Know? A Person Can Test HIV Negative but be Very Infecticious!

[Fast and Furious]

During the window period a person can have HIV and be very infectious but still test HIV negative. The window period is the time between HIV infection and the point when the test will give an accurate positive result. Read More. Now you know, testing HIV negative is not a guarantee that you're not infected! You will need to test several times to confirm or debunk the previous tests after a significant amount of time (on average 4 to 12 weeks) from the date of potential exposure.

The window period for a 4th generation antigen/antibody test is about four weeks. By this time 95% of infections will be detected. There is a three month window period after exposure, for the confirmatory result to detect more than 99.9% of infections.
