Step-by-step solution for: Blood Typing worksheet
To solve this blood typing problem, we need to interpret the agglutination results in the chart. Agglutination (clumping) occurs when antibodies react with antigens on red blood cells.
Here's how blood typing works:
- Anti-A serum: If agglutination occurs → A antigen is present → Blood type has A.
- Anti-B serum: If agglutination occurs → B antigen is present → Blood type has B.
- Anti-D serum: If agglutination occurs → Rh factor is positive (+) → Blood is Rh+.
- Control: Should have no agglutination; used to confirm test validity.
---
- 🟨 Agglutination = Clumped cells (patterned circle)
- 🔴 No agglutination = Smooth red circle
We'll go row by row and determine the blood type based on which tests show agglutination.
---
Let’s analyze each patient (row):
---
Row 1:
- Anti-A: ✘ No agglutination
- Anti-B: ✘ No agglutination
- Anti-D: ✔ Agglutination
- Control: ✘ No agglutination
→ No A or B antigens → O
→ Rh positive (D antigen present)
✔ Blood Type: O+
---
Row 2:
- Anti-A: ✔ Agglutination
- Anti-B: ✔ Agglutination
- Anti-D: ✔ Agglutination
- Control: ✘ No agglutination
→ A and B antigens → AB
→ Rh positive
✔ Blood Type: AB+
---
Row 3:
- Anti-A: ✔ Agglutination
- Anti-B: ✘ No agglutination
- Anti-D: ✔ Agglutination
- Control: ✘ No agglutination
→ A antigen present, B absent → A
→ Rh positive
✔ Blood Type: A+
---
Row 4:
- Anti-A: ✔ Agglutination
- Anti-B: ✘ No agglutination
- Anti-D: ✘ No agglutination
- Control: ✘ No agglutination
→ A antigen present, B absent → A
→ Rh negative
✔ Blood Type: A−
---
Row 5:
- Anti-A: ✘ No agglutination
- Anti-B: ✔ Agglutination
- Anti-D: ✔ Agglutination
- Control: ✘ No agglutination
→ B antigen present, A absent → B
→ Rh positive
✔ Blood Type: B+
---
Row 6:
- Anti-A: ✔ Agglutination
- Anti-B: ✔ Agglutination
- Anti-D: ✘ No agglutination
- Control: ✘ No agglutination
→ A and B antigens → AB
→ Rh negative
✔ Blood Type: AB−
---
Row 7:
- Anti-A: ✘ No agglutination
- Anti-B: ✔ Agglutination
- Anti-D: ✘ No agglutination
- Control: ✘ No agglutination
→ B antigen present, A absent → B
→ Rh negative
✔ Blood Type: B−
---
| Blood Type | ANTI-A | ANTI-B | ANTI-D | CONTROL |
|------------|--------|--------|--------|---------|
| O+ | ✘ | ✘ | ✔ | ✘ |
| AB+ | ✔ | ✔ | ✔ | ✘ |
| A+ | ✔ | ✘ | ✔ | ✘ |
| A− | ✔ | ✘ | ✘ | ✘ |
| B+ | ✘ | ✔ | ✔ | ✘ |
| AB− | ✔ | ✔ | ✘ | ✘ |
| B− | ✘ | ✔ | ✘ | ✘ |

✔ Completed Chart:
```
Blood Type: O+
Blood Type: AB+
Blood Type: A+
Blood Type: A−
Blood Type: B+
Blood Type: AB−
Blood Type: B−
```
This is the correct interpretation of the agglutination patterns for each patient.
Here's how blood typing works:
- Anti-A serum: If agglutination occurs → A antigen is present → Blood type has A.
- Anti-B serum: If agglutination occurs → B antigen is present → Blood type has B.
