Question
A visual representation of a blood typing test card is shown in the image above. The card has three fields labeled as A, B, and Rh. A drop of blood is placed in each of these fields:
- **Field A:** Shows agglutination (clumping of red blood cells), which is indicated by a noticeable change in the texture and color of the blood sample, generally becoming grainy or speckled.
- **Field B:** Also shows agglutination.
- **Field Rh:** Shows no agglutination.
**Options:**
- ○ **ELISA (Enzyme-Linked Immunosorbent Assay)**
- ○ **Precipitation**
- ○ **Complement Fixation**
Consider the visual cues and the nature of agglutination in the A and B fields to determine the type of test being described.
This image represents a **Blood Typing Test**, which is not covered by the options listed. The primary purpose of this test is to determine the blood type (A, B, AB, or O) and Rh factor (positive or negative) of an individual.
**Explanation of Blood Typing Test:**
1. **A Field:** The presence of agglutination indicates that the blood sample has A antigens.
2. **B Field:** The presence of agglutination indicates that the blood sample has B antigens.
3. **Rh Field:** The absence of agglutination indicates that the blood sample does not have Rh antigens (Rh negative).
