Normal Laboratory Values

Overview

• Understanding normal laboratory values is crucial for interpreting medical tests.
• Some patients may have personalized 'abnormal normal' ranges set by their healthcare provider.
• The focus is on recognizing standard normal ranges.

Hemoglobin

• Males: 13 to 18 g/dL
• Females: 12 to 16 g/dL
  • Women may have lower levels due to menstrual cycles.

Hematocrit

• Males: 42 to 52%
• Females: 36 to 48%

Erythrocyte Sedimentation Rate (ESR)

• Males: 0 to 20 mm/hr
• Females: 0 to 30 mm/hr

Fasting Blood Glucose (FBS)

• Normal range: 60 to 110 mg/dL

Cholesterol Levels

• Total Cholesterol: Less than 200 mg/dL
• LDL (Low Density Lipoprotein): Less than 130 mg/dL
• HDL (High Density Lipoprotein): Greater than 40 mg/dL
• Triglycerides: Less than 150 mg/dL

Coagulation Tests

• Prothrombin Time (PT): 10.4 to 15.7 seconds
• International Normalized Ratio (INR): 0.8 to 1.2

Urine Tests

• Includes both qualitative and quantitative results.
• pH Level: 4.8 to 8
• Specific Gravity: 1.005 to 1.030
• Urobilinogen: 0.1 to 1
• Other values typically reported as negative.

Key Points

• Lab values can have qualitative (positive/negative) and quantitative (numerical) results.
• Providers may specify which abnormal values to report.
• Being familiar with these normal ranges aids in effective healthcare delivery.
