Following Talent Testings lead, CET is now offering a Gen4 antibody/antigen test to measures someone’s ‘True” HIV status.
Although they have yet to update their website to reflect this information, they did confirm it via Twitter and this graphic shows the latest test result which was provided by the APAG.
The addition of the test is contradictory to the recent FSC statement. “FSC-PASS had previously evaluated this antibody test, but found it offered no additional risk reduction for performers.”
I’m not sure why CET changed their minds, but I’m glad they did. This is a step forward in protecting performers.

antigen tests are great to weed out new infections, they do nothing to weed out treated HIV which can only be detected by antibody testing.

p24 antigen is a viral protein that makes up most of the viral core.
Serum concentrations of p24 antigen are high in the first few weeks after infection; tests sensitive to p24 antigen are therefore useful for diagnosing very early infection when antibody levels are still low.
One distinctive HIV antigen is a viral protein called p24, a structural protein that makes up most of the HIV viral core, or ‘capsid’. High levels of p24 are present in the blood serum of newly infected individuals during the short period between infection and seroconversion, making p24 antigen assays useful in diagnosing primary HIV infection.
Antibodies to p24 are produced during seroconversion, rendering p24 antigen undetectable after seroconversion in most cases. Therefore, p24 antigen assays are not reliable for diagnosing HIV infection after its very earliest stages. However, HIV infection can be reliably diagnosed earlier with combined antibody/antigen tests than with purely antibody-detecting tests, and fourth-generation antibody/antigen tests are now the standard screening assay in the UK and some other countries.
