Question
A person is infected by HIV. How will you diagnose for AIDS?
Short Note
Solution
A simple blood test is available that can determine whether the person has been infected with HIV. The ELISA test (Enzyme-Linked Immunosorbent Assay) detects the presence of HIV antibodies. It is a preliminary test. Western blot test is more reliable and a confirmatory test. It detects the viral core proteins. If both tests detect the presence of the antibodies, the person is considered to be HIV positive.
