What are normal MCV values?

The normal MCV range is 80–100 fL in adults. Values below 80 fL indicate microcytosis (small cells, often seen in iron deficiency or thalassemia). Values above 100 fL indicate macrocytosis (large cells, often seen in B12/folate deficiency or liver disease).

What are normal MCH values?

Normal MCH is 27–33 pg per cell. Low MCH (hypochromia) typically accompanies low MCV and suggests iron deficiency anemia. Elevated MCH often accompanies macrocytosis.

What are normal MCHC values?

Normal MCHC is 32–36 g/dL. Low MCHC confirms hypochromia and often indicates iron deficiency. High MCHC (above 36 g/dL) is rare and may suggest hereditary spherocytosis or a lab error.

Why does my lab report show different values than this calculator?

Modern hematology analyzers measure MCV directly by impedance or light scatter, then derive RBC count and calculate MCH and MCHC. Small differences can arise from rounding or analyzer-specific calibration. This calculator uses the standard textbook formulas.

Is this tool a substitute for clinical judgment?

No. Results are for educational and reference use only. Diagnosis and treatment decisions must be made by a qualified healthcare professional considering the full clinical picture, patient history, and additional laboratory findings.

Summary

Enter RBC count, hemoglobin, and hematocrit to instantly calculate MCV, MCH, and MCHC with normal range interpretation.

How it works

Enter the RBC count in millions per microliter (10^6/µL).
Enter the hemoglobin level in grams per deciliter (g/dL).
Enter the hematocrit as a percentage (%).
The calculator applies standard formulas: MCV = (Hct / RBC) × 10, MCH = (Hgb / RBC) × 10, MCHC = (Hgb / Hct) × 100.
Each result is displayed with its unit, normal range, and a low/normal/high flag for quick interpretation.

Use cases

Classifying anemia type (microcytic, normocytic, or macrocytic) from CBC results.
Evaluating iron deficiency versus B12/folate deficiency based on cell indices.
Monitoring treatment response in patients receiving iron or vitamin supplementation.
Medical student study aid for understanding CBC interpretation.
Quick bedside reference for clinicians reviewing lab printouts.
Cross-checking lab analyzer output against manual formula calculations.
