Errors In ESR Flashcards
1
Q
Macrocytes
A
Bigger RBC » heavier » faster sedimentation = ↑ESR
2
Q
• Microcytes
A
→ Smaller RBC » lighter » slower sedimentation = ↓ESR
3
Q
Anemia
A
→ ↓RBC » less congested » faster sedimentation = ↑ESR
4
Q
Rouleaux formation (stacked coin appearance)
A
→ Present » heavier » faster sedimentation = ↑ESR
5
Q
Anemia
A
→ ↓RBC » less congested » faster sedimentation = ↑ESR
5
Q
Poikilocytes
A
→ Abnormal shape » no RF » scattered » slower
sedimentation = ↓ESR
6

A
4 hours of blood collection
