An iron-rich protein in red blood cells
What’s normal
Men: 14-17 gm/dL
Women: 12-15 gm/dL
What abnormal
results can mean:
• Anemia

Cells/mcL = cells per microliter; gm/dL = grams per deciliter
HEMATOCRIT
Shows how much space
red blood cells take up
in your blood
What’s normal
Men: 41-50%
Women: 36-44%
