How is corrected esr calculated?

Corrected erythrocyte sedimentation rate (ESR) is calculated by adjusting the standard ESR values based on the patient's hematocrit level. The formula typically used is: Corrected ESR = Measured ESR × (100 - Hematocrit) / 100. This adjustment accounts for the dilution effect of red blood cells on the sedimentation rate, providing a more accurate reflection of inflammatory activity in individuals with abnormal hematocrit levels.
