A person suspected to suffer from AIDS isadvised to undergo diagnostic test

Options

A. ultrasound
B. WIDAL
C. MRI
D. ELISA

Answer

**Step-by-Step Solution:**

1. **Understanding the Condition**: The question mentions a person suspected of having AIDS, which is caused by the Human Immunodeficiency Virus (HIV). AIDS is a serious viral infection that affects the immune system.

2. **Identifying Diagnostic Tests**: The question provides four options for diagnostic tests: ultrasound, Vidal test, MRI, and ELISA. We need to determine which of these tests is specifically used to diagnose HIV/AIDS.

3. **Evaluating Each Option**:
- **Ultrasound**: This imaging technique is primarily used to visualize internal organs and is not used for diagnosing AIDS. Therefore, this option is incorrect.
- **Vidal Test**: This test is used to diagnose typhoid fever, not HIV/AIDS. Hence, this option is also incorrect.
- **MRI**: Magnetic Resonance Imaging is another imaging technique that is used for various medical conditions but is not specific for diagnosing HIV/AIDS. Thus, this option is incorrect as well.
- **ELISA**: The Enzyme Linked Immunosorbent Assay (ELISA) is a widely used laboratory test for detecting antibodies to HIV in the blood. It is specifically designed to diagnose HIV infections and is the most appropriate test for someone suspected of having AIDS.

4. **Conclusion**: After evaluating all the options, the correct diagnostic test for a person suspected of suffering from AIDS is the ELISA test. Therefore, the answer is option D: ELISA.
