Reference ranges for lab tests can vary slightly between different laboratories due to differences in equipment, methods, and population samples.
However, general reference ranges for common lab tests in adults are widely accepted. Here are some of the most common lab tests and their typical reference ranges:
Complete Blood Count (CBC)
Red Blood Cells (RBC):
Men: 4.3-5.9 million cells/�L
Women: 3.5-5.5 million cells/�L
Hemoglobin (Hb):
Men: 13.8-17.2 g/dL
Women: 12.1-15.1 g/dL
Hematocrit (Hct):
Men: 38.3-48.6%
Women: 34.9-44.5%
White Blood Cells (WBC):
4.5-11.0 thousand cells/�L
Platelets:
150-450 thousand cells/�L
Important Considerations
Individual Variability: Reference ranges can vary based on individual factors such as age, sex, and overall health status.
Lab-Specific Ranges: Different laboratories may have slightly different reference ranges due to variations in testing methods and equipment.
Consult a Healthcare Provider: Always consult a healthcare provider for the interpretation of lab test results, as they can provide context and personalized advice.
By understanding these reference ranges, you can have a better idea of what your lab test results mean. However, it's crucial to discuss your results with a healthcare provider for accurate interpretation and appropriate medical advice.
