ANC
|
Absolute Neutrophil Count

|
What are the ESR (Erythrocyte Sedimentation Rate) and CRP (C-Reactive Protein)?
|
ESR: < 20 mm/hr, measures how quickly the erthyrocytes settle.
- increases slowly and returns to baseline after several days. CRP: 0.08-3.1 mg/L - elevated within hours and declines to baseline over several days - marker of acute injury, infection or inflam. |
