4th generation tests are accurate 14 days after exposure, because this is when the p24 antigen becomes high enough to measure; effectively reducing the window period by average of 14 days. A negative result at 28 days is good news but it is not conclusive and an early negative result at 28 days (1 month) needs to be confirmed with a second test 90 days (3 months) after the exposure.
