Does the accuracy percentage take into consideration the window period and interference from other medications or does it stay at 99.7% after the window period i.e. would it be possible to get a false negative for absolutely no reason?
Hi J613,
The ability of the test to be able to accurately detect infection is based on the rate of antibody production. The accuracy of the test is 99.7% throughout. Everyone produces antibodies at different rates which is why our test has a 12 week window period. You can test at anytime during this period but must always retest 12 weeks post exposure for a conclusive result. The only medication that can affect the result of the test is PEP and PrEP. The user must wait 12 weeks after finishing their course of PEP or PrEP before relying on their result. Testing inside the window period or whilst on PEP or PrEP is likely to cause the test to give a false negative result - these do not happen for absolutely no reason. I hope this helps. Kindest regards, Becky
