What is a RBC Indices?
The RBC Indices Calculator computes MCV, MCH, and MCHC from hematocrit, hemoglobin, and RBC count — three standard red blood cell indices used as a starting reference point in evaluating anemia patterns. This is a standard CBC reference calculation, not a diagnostic tool.
For a related simple ratio, see the Mentzer Index Calculator.
How to use this RBC Indices calculator
- Enter your hematocrit percentage.
- Enter your hemoglobin value in g/dL.
- Enter your RBC count in millions per microliter.
- Read the MCV, MCH, and MCHC results instantly.
- Discuss any specific lab results with a qualified healthcare professional for proper interpretation.
Formula & Methodology
MCV (fL) = (Hematocrit % ÷ RBC Count) × 10 MCH (pg) = (Hemoglobin ÷ RBC Count) × 10 MCHC (g/dL) = (Hemoglobin ÷ Hematocrit %) × 100 Worked example — hematocrit 42%, hemoglobin 14 g/dL, RBC count 4.8 million/µL: MCV = (42 ÷ 4.8) × 10 = 87.5 fL MCH = (14 ÷ 4.8) × 10 = 29.2 pg MCHC = (14 ÷ 42) × 100 = 33.3 g/dL
Frequently Asked Questions
RBC (red blood cell) indices are a set of derived values — MCV, MCH, and MCHC — calculated from a complete blood count that describe the size and hemoglobin content of red blood cells, commonly used as a starting reference point in evaluating anemia patterns.
MCV (Mean Corpuscular Volume) describes the average size of red blood cells, calculated from hematocrit and RBC count, and expressed in femtoliters (fL).
MCH (Mean Corpuscular Hemoglobin) describes the average amount of hemoglobin per red blood cell, calculated from hemoglobin and RBC count, and expressed in picograms (pg).
MCHC (Mean Corpuscular Hemoglobin Concentration) describes the average concentration of hemoglobin within red blood cells, calculated from hemoglobin and hematocrit, and expressed in g/dL.
No — this calculator performs the mathematical conversions only. Interpreting what specific RBC index values mean for your health requires a qualified healthcare professional reviewing your complete lab results and clinical history.
Hematocrit, hemoglobin, and RBC count are all standard components of a complete blood count (CBC), commonly reported together on routine blood test results.
The MCV calculated here can be used directly as an input for the [Mentzer Index Calculator](/mentzer-index-calculator/), which combines MCV with RBC count into a single simple ratio sometimes referenced in anemia discussions.
MCV, MCH, and MCHC each describe a different aspect of red blood cell characteristics — size, hemoglobin content, and hemoglobin concentration respectively — and together give a more complete picture than any single value alone.
MCV is expressed in femtoliters (fL), MCH in picograms (pg), and MCHC in grams per deciliter (g/dL), matching standard CBC reporting conventions.
Yes — these are standard, widely used formulas that apply to any complete blood count report with hematocrit, hemoglobin, and RBC count values, regardless of the lab or country of origin.
