  • HIV and the p24 Antigen

About this test

This test uses a rapid lateral-flow device to check for HIV 1 and 2 antibodies and the p24 antigen from a finger-prick or blood sample, giving a result at the clinic in around 20 minutes rather than waiting for a lab turnaround. Better2Know includes a confirmatory laboratory test at no extra cost if the initial result is reactive.

At £185, it's priced right at the £185 median for this HIV comparison group, more than Better2Know's own HIV Home Test Kit (£65) and HIV 4th Generation Test (£145), but well below its PCR-based tests at £295 and £495.

Collection convenience scores only moderately here because, unlike other tests in the range, this one is only offered at selected clinics rather than at home. Clarity scores well thanks to a detailed description of the process, and results and follow-up scores only moderately since there's no doctor review as standard, though further testing and referral are available if the result is reactive.

Who is it for?

This suits someone who wants a same-visit HIV result rather than waiting a day or more for lab-based tests, and who is happy to attend one of Better2Know's selected instant-testing clinics.

If you'd rather test at home, Better2Know's own HIV Home Test Kit (£65) or HIV 4th Generation Test (£145) cost less, though results take longer to come back.

How it works

At a selected clinic, a clinician takes a finger-prick or blood sample and runs it on a rapid test strip alongside a chase buffer, giving a result in around 20 minutes. You receive a signed Rapid Test Results Report; if reactive, a further venous sample is sent to the laboratory for confirmatory testing at no extra cost. The fact sheet does not state that a doctor reviews the result before you see it.
