Question

Early detection of HIV in suspected AIDS patients can be done using the diagnostic technique of:

• A. ELISA
• B. PCR
• C. EST
• D. RNAI

Hint:

ELISA is widely used for initial HIV screening due to its high sensitivity in detecting HIV antibodies, often followed by PCR for confirmation.

Answer 1

The Correct Option is A

ELISA (Enzyme-Linked Immunosorbent Assay) is the standard first-line test for early detection of HIV in suspected AIDS patients, as it detects antibodies against HIV in the blood. PCR can confirm HIV by detecting its DNA/RNA but is typically used as a follow-up. EST and RNAI (likely RNAi) are not diagnostic tools for HIV.
