A certain patient is suspected to be suffering from Acquired Immune Deficiency Syndrome. Which diagnostic technique will you recommend for its detection?

Options

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

Explanation

**Step-by-Step Solution:**

1. **Understanding the Condition**: The question involves a patient suspected of having Acquired Immune Deficiency Syndrome (AIDS). AIDS is caused by the Human Immunodeficiency Virus (HIV), which leads to a significant decrease in the immune system's ability to fight infections.

2. **Identifying Diagnostic Techniques**: The options provided for diagnostic techniques are:
- A. ELISA
- B. MRI
- C. Ultrasound
- D. Vidal test

3. **Evaluating Each Option**:
- **ELISA (Enzyme-Linked Immunosorbent Assay)**: This technique is specifically designed to detect the presence of antibodies or antigens in a sample. It is highly sensitive and can detect small amounts of proteins or glycoproteins associated with HIV.
- **MRI (Magnetic Resonance Imaging)**: This imaging technique is used primarily for visualizing internal structures of the body, such as tumors or brain structures, and is not used for diagnosing AIDS.
- **Ultrasound**: Similar to MRI, ultrasound is used for imaging internal organs and is not applicable for diagnosing AIDS.
- **Vidal Test**: This test is used for diagnosing typhoid fever and is not relevant for AIDS.

4. **Conclusion**: Based on the evaluation, the most appropriate diagnostic technique for detecting AIDS is the ELISA test. This test detects the presence of antibodies against HIV in the patient's blood.

5. **Final Answer**: Therefore, the recommended diagnostic technique for detecting Acquired Immune Deficiency Syndrome (AIDS) is **A. ELISA**.
