The NAT (Nucleic Acid Testing) is a method used to directly detect the presence of viral RNA or DNA in a sample. It is highly sensitive and can detect the virus even at early stages of infection.
ELISA (Enzyme-Linked Immunosorbent Assay) is a general term for a laboratory technique that detects the presence of antibodies or antigens in a sample. In the context of HIV testing, an HIV ELISA test detects HIV-specific antibodies produced by the immune system in response to an HIV infection.
Western Blot is a laboratory technique that confirms the presence of specific proteins in a sample. It is commonly used as a confirmatory test for HIV infection after a positive screening test. Western Blot detects antibodies against specific HIV proteins.
DUO refers to a specific type of HIV test that combines the detection of both HIV antibodies and the HIV P24 antigen. The P24 antigen is a viral protein produced early during HIV infection. The HIV DUO test is more sensitive than a standard antibody-only test, as it can detect the P24 antigen in the early stages of infection when antibodies may not have developed yet.
P24 specifically refers to the HIV P24 antigen. It is a protein component of the HIV virus that can be detected in the blood during the early stages of infection before antibodies become detectable.
So,here is your answer .
NAT is a direct detection method for viral RNA or DNA, Elisa DUO P24 detects HIV P24 antigen and antibodies, and Western Blot confirms the presence of specific HIV proteins that can be detected in the blood.
