Ok thanks for the info

Hi Sam01, The confirmatory test is a lab test (4th gen) so will pick up the presence of the p24 antigen also. If the lab test was negative, and the previous BioSure test was positive, we would class this as a false positive from using our test. Kindest regards, Becky

So they would only need to perform a 4th generation test to confirm the result? If the 4th generation test results are negative after a positive biosure test would the person have to have even more tests?

Hi Sam01, If someone was to receive a positive result from using our self-test, they would need to get their result confirmed by a health care professional. This can be done at a GUM clinic or with your doctor. The tests performed at GUM clinics are usually 4th generation and therefore have a shorter window period, since the test looks for the presence of the p24 antigen whereas our self test simply looks for the antibodies to HIV. The test itself is not necessarily more accurate than ours but there is less risk of a false result due to a trained professional performing the test. This is not to say that self-testing is inaccurate but when false results do occur it is often because users are unable to follow the instructions properly. The efficacy of our self test has been proven to be effective when used by lay individuals but this is not to say that human error is completely eliminated, which is why we always say that if a person receives a positive result it must be confirmed by a professional. Since GUM clinics are not currently open due to COVID-19, if you receive a positive result, you must speak to your GP/doctor regarding this and get a confirmatory test done as soon as possible. I hope this helps. Kindest regards, Becky
