P 24 Antigen Test
The P24 antigen detection is also used in the early diagnosis of HIV as it is a distinctive HIV antigen. This test allows us to diagnose the infection independent of antibodies production against HIV. The procedure of P24 antigen assay is EIA-based and also aid the confirmation in the presence of HIV antibodies. The test is rarely effective as the antigen can’t be detected until antibodies production. P24 antigen detection is useful for patients who are highly symptomatic but have ELISA negative tests or have ELISA positive with Western Blot negative.
