Answer
I. Laboratory diagnosis :
- There are two tests for diagnosis of AIDS.
- First test is ELISA (Enzyme-Linked Immunosorbent Assay) which is used to detect the HIV antibodies.
- The second confirmatory test is Western Blot, which is used to weed out any false positive results. It is a highly specific test.
- It is based on detecting specific antibody to viral core protein and envelope glycoprotein.
- AIDS cannot be cured.
- Antiretroviral drugs are used to reduce the viral load and prolong the life of HIV patient. E.g. Antiretroviral therapy (ART) uses drugs such as TDF (tenofovir), EFV (Efavirenz), Lamivudine (3TC), etc.
