ELISA is used in detection of

Options

A. Hay fever
B. Tetanus
C. AIDS
D. Tuberculosis

Answer

**Step-by-Step Solution:**

1. **Understanding ELISA**: ELISA stands for Enzyme-Linked Immunosorbent Assay. It is a laboratory technique used to detect and quantify proteins, antibodies, or hormones in a sample.

2. **Identifying the Diseases**: The question lists four options: hay fever, tetanus, AIDS, and tuberculosis. We need to determine which of these diseases can be detected using the ELISA method.

3. **Analyzing Each Option**:
- **Hay Fever**: This is an allergic reaction typically caused by pollen. While blood tests can detect IgE antibodies related to hay fever, ELISA is not the primary method used for diagnosis.
- **Tetanus**: Tetanus is diagnosed through clinical examination and patient history. ELISA is not commonly used for diagnosing tetanus.
- **AIDS**: Acquired Immunodeficiency Syndrome (AIDS) is caused by the Human Immunodeficiency Virus (HIV). ELISA is widely used to detect antibodies against HIV in blood samples, making it a crucial diagnostic tool for AIDS.
- **Tuberculosis**: Tuberculosis (TB) is typically diagnosed using the Mantoux test (tuberculin skin test) or other imaging techniques, not ELISA.

4. **Conclusion**: Based on the analysis, the disease that can be detected using the ELISA method is AIDS.

5. **Final Answer**: The correct answer is **AIDS**.
