A negative result at 28 days is good news but it is not conclusive. UK guidelines (BASHH) say that an early negative result at 28 days (1 month) needs to be confirmed with a second test 90 days (3 months) after the exposure."
The first paragraph is based on the 2014 US CDC Updated Guidelines for the Lab Diagnosis of HIV. It ONLY refers to lab based 4th Gen testing and makes the statement that the P24 antigen is detectable from D14.
However, please read the 2nd paragraph which quotes the BASHH guidelines that say all rapid tests need to be confirmed at 90 days post exposure. This same recommendation can be found in the US and Australasian guidelines.
It is important to take all information into consideration and not take one sentence out of context. This may lead to misunderstanding or misinformation.
