Let me analyze the image carefully to determine the blood types for each patient based on agglutination patterns.
First, I need to understand what the chart shows:
- There are 8 rows (patients)
- Each row has 4 tests: ANTI-A, ANTI-B, ANTI-D, and CONTROL
- Agglutination (clumping) is shown as a patterned red circle
- No agglutination is shown as a solid red circle
- The legend tells us: patterned = agglutination, solid = no agglutination
In blood typing:
- Anti-A reacts with A antigens → agglutination means blood type has A antigen
- Anti-B reacts with B antigens → agglutination means blood type has B antigen
- Anti-D reacts with Rh factor (D antigen) → agglutination means Rh positive (+)
- Control should have no agglutination (to confirm test validity)
Let me go row by row:
Row 1: ANTI-A (no agglutination), ANTI-B (no agglutination), ANTI-D (agglutination), CONTROL (no agglutination)
→ No A, no B, Rh+ → Type O+
Row 2: ANTI-A (no agglutination), ANTI-B (no agglutination), ANTI-D (no agglutination), CONTROL (no agglutination)
→ No A, no B, Rh- → Type O-
Row 3: ANTI-A (agglutination), ANTI-B (no agglutination), ANTI-D (agglutination), CONTROL (no agglutination)
→ A present, no B, Rh+ → Type A+
Row 4: ANTI-A (agglutination), ANTI-B (no agglutination), ANTI-D (no agglutination), CONTROL (no agglutination)
→ A present, no B, Rh- → Type A-
Row 5: ANTI-A (no agglutination), ANTI-B (agglutination), ANTI-D (agglutination), CONTROL (no agglutination)
→ No A, B present, Rh+ → Type B+
Row 6: ANTI-A (no agglutination), ANTI-B (agglutination), ANTI-D (no agglutination), CONTROL (no agglutination)
→ No A, B present, Rh- → Type B-
Row 7: ANTI-A (agglutination), ANTI-B (agglutination), ANTI-D (agglutination), CONTROL (no agglutination)
→ A present, B present, Rh+ → Type AB+
Row 8: ANTI-A (agglutination), ANTI-B (agglutination), ANTI-D (no agglutination), CONTROL (no agglutination)
→ A present, B present, Rh- → Type AB-
Let me double-check the control column - all show no agglutination (solid red), which is correct for controls.
Now I'll provide the final answer as requested.
Final Answer:
O+, O-, A+, A-, B+, B-, AB+, AB-
