Description
Purified recombinant HIV1 p24 protein
HIV tests are used to detect the presence of the human immunodeficiency virus in serum, saliva, or urine. Such tests may detect HIV antibodies, antigens, or RNA. The p24 antigen test detects the presence of the p24 protein of HIV (also known as CA), the capsid protein of the virus. The p24 antigen test is not useful for general diagnostics, as it has very low sensitivity and only works during a certain time period after infection before the body produces antibodies to the p24 protein
