Question

Laboratory diagnosis of HIV infection is done through which of the following tests? A. Absolute CD4 lymphocyte count B. WESTERN Blot C. HIV viral load test D. ELISA test

• A. D and B
• B. A and C
• C. A, C and D
• D. C and D

Hint:

ELISA and HIV viral load tests are commonly used for the diagnosis and monitoring of HIV infection.

Answer 1

The Correct Option is D

Step 1: Understanding HIV Diagnostic Tests.
HIV infection is mainly diagnosed in the lab using ELISA (Enzyme-Linked Immunosorbent Assay) and HIV viral load tests.
- ELISA (D) identifies HIV antibodies.
- HIV viral load testing (C) quantifies HIV in the blood, indicating infection severity.
- Western Blot (B) typically confirms positive ELISA results; Absolute CD4 count (A) assesses immune status but isn't for initial diagnosis.
