A certain patient is suspected to be suffering from acquired immuno deficiency syndrome. Which diagnostic technique will you recommend for its detection?

Step-by-step solution

ELISA (Enzyme-linked Immunosorbent Assay), also known as an enzyme immunoassay (EIA), is a biochemical technique used mainly in immunology to detect the presence of an antibody or an antigen in a sample. It is a useful tool for determining serum antibody concentrations (such as with the HIV test). The ELISA was the first screning test widely used for HIV because of its high sensitivity.
