Computes the three standard published red blood cell indices from RBC count, hemoglobin, and hematocrit: MCV = (Hct x 10) / RBC, MCH = (Hgb x 10) / RBC, MCHC = (Hgb x 100) / Hct. Commonly cited normal adult reference ranges: MCV ~80-100 fL, MCH ~27-33 pg, MCHC ~32-36 g/dL. Pure arithmetic on given lab values. For general reference and educational purposes only — not a medical diagnosis. Consult a doctor for actual interpretation of a complete blood count.
How it works
Enter RBC count, hemoglobin, and hematocrit from a complete blood count. The tool applies all three standard index formulas and compares each to its commonly cited reference range.
- Enter rBC count (x10^6/uL).
- Enter hemoglobin (g/dL).
- Enter hematocrit (%).
- Click Calculate to see your results.
Examples
RBC 5, Hgb 15, Hct 45
MCV = (45x10)/5 = 90 fL. MCH = (15x10)/5 = 30 pg. MCHC = (15x100)/45 = 33.3 g/dL — all within commonly cited normal ranges.
Who should use it
- Reviewing a complete blood count.
- Anemia classification education.
Industry applications
- Hematology reference
- Clinical education
Advantages
- Computes all three standard indices in one tool.
- Includes commonly cited reference ranges for context.
Limitations
- Reference ranges vary slightly by lab and age.
- Does not replace clinical interpretation.
Common mistakes to avoid
- Mixing up which lab value goes with which formula — double-check RBC, Hgb, and Hct are entered in their standard units.
Best practices
- Review all three indices together, alongside the RBC count and other CBC values, rather than in isolation.
Tips
- MCV is often the first index used to classify an anemia as microcytic, normocytic, or macrocytic, per standard hematology teaching.
