Detailed explanation-1: -ELISA Test ELISA, which stands for enzyme-linked immunosorbent assay, is used to detect HIV infection. If an ELISA test is positive, the Western blot test is usually administered to confirm the diagnosis. If an ELISA test is negative, but you think you may have HIV, you should be tested again in one to three months.

Detailed explanation-2: -Enzyme-linked immunosorbent assay (ELISA) is a labeled immunoassay that is considered the gold standard of immunoassays. This immunological test is very sensitive and is used to detect and quantify substances, including antibodies, antigens, proteins, glycoproteins, and hormones.

Detailed explanation-3: -The ELISA test, also called the EIA for enzyme immunoassay, is used to detect the HIV antibody. It checks for certain proteins that the body makes in response to HIV. The blood sample will be added to a cassette that contains the viral protein, called antigen.

Detailed explanation-4: -Nucleic Acid Test (NAT) With a NAT, the health care provider will draw blood from your vein and send the sample to a lab for testing. This test can tell if a person has HIV or how much virus is present in the blood (HIV viral load test).
