  • HIV and the p24 Antigen

About this test

This test checks for HIV antibodies and the p24 antigen using what's known as a 4th generation method, which combines both markers in one blood test. It is the standard type of HIV test used for a first check after a suspected exposure, once the recommended incubation period has passed.

Against the group's £185 median, this test's £145 price makes it one of the better-value options here, cheaper than Better2Know's own instant clinic tests (£185) and its PCR-based tests (£295 and £495), though still more than the cheapest options in the group such as a Medichecks HIV Blood Test (£49) or Better2Know's own HIV Home Test Kit (£65).

The clarity score is high because the listing sets out the sample type, biomarker and turnaround clearly. value for money scores well given the discount to the group median, while results and follow-up score only moderately because the result is not reviewed by a doctor as standard.

Who is it for?

This suits someone who wants a standard, well-established HIV test after the recommended incubation period, attending a clinic or having a nurse visit at home, with results back the next working day.

If cost matters more than attending in person, Better2Know's own HIV Home Test Kit uses the same biomarker for £65, and Medichecks offers a HIV Blood Test for £49; both are considerably cheaper alternatives to this clinic-based version.

How it works

A clinician takes a venous blood sample at a clinic, or a nurse can visit you at home; a £65 home test kit version is also available. The sample is analysed at the laboratory and results are uploaded to your online patient area the next working day, with a notification by phone, email or SMS. The fact sheet does not state that a doctor reviews the result before you see it.
