Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which test is NOT used to diagnose AIDS. AIDS (Acquired Immunodeficiency Syndrome) is caused by the Human Immunodeficiency Virus (HIV).

2. **Analyzing the Options**:
- **Option 1: Enzyme Linked Immunosorbent Assay (ELISA)**: This test is commonly used to detect HIV antibodies in the blood. Since it is used for diagnosing HIV, it is relevant for AIDS diagnosis.
- **Option 2: Vidal Test**: This test is used to diagnose typhoid fever, not AIDS. Therefore, it is not relevant for diagnosing AIDS.
- **Option 3: Rapid Initiation of ART (RIA)**: This refers to the initiation of Anti-Retroviral Treatment, which is used to manage HIV infection and can indicate the presence of AIDS. Thus, it is relevant for AIDS diagnosis.

3. **Conclusion**: The test that is NOT used to diagnose AIDS is the Vidal test.

**Final Answer**: AIDS is not diagnosed by the Vidal test.
