Lab Test Ranges and Exercise Guidelines

Lab Test Ranges and Exercise Contraindications

• White Blood Cell Count (WBC):

  • Males: 5,000-11,000 cells/mm³
  • Females: 5,000-11,000 cells/mm³
  • <1,000/mm³: no exercise
  • <5,000/mm³ or 10,000 with fever: no exercise

• Hemoglobin (Hgb):

  • Males: 13-18 g/dl
  • Females: 12-16 g/dl
  • Hgb < 8 g/dl: decreased exercise tolerance
  • HCT <25%: no exercise

• Hematocrit (HCT):

  • Males: 37-49%
  • Females: 36-46%
  • HCT <25%: no exercise

• Platelet Count: 150,000-450,000 cells/mm³

  • <20,000/mm³: no exercise

• Activated Partial Thromboplastin Time (aPTT): Intrinsic coag 20-40 seconds

• International Normalized Ratio (INR): 0.9-1.1

  • 2.5-3: no exercise

• Erythrocyte Sedimentation Rate (ESR):

  • 0-17 mm/hr
  • 1-25 mm/hr: if pregnant
  • 44-114 mm/hr: exercise contraindicated

• Blood Glucose: 70-110 mg/dl

  • 70 mg/dl or less: give carbohydrates, monitor anything above 100 mg/dl

• Potassium (K+): 3.5-5.0 mEq/l

  • <3.2 or >5.1 mEq/l: no exercise

• Sodium (Na+): 135-145 mEq/l

  • <135 mEq/l or >145 mEq/l: no exercise
