What this calculator does
MCH & MCHC (red cell indices) works out average haemoglobin content and concentration per red blood cell, from a full blood count. Enter your own figures above and the answer updates as you type: nothing is fixed in the code, so the result reflects exactly the numbers you supply.
The formula this calculator evaluates is printed under the tool and explained below, so you can check the working by hand or reuse it in a spreadsheet.
The formula
FormulaMCH (pg) = Hgb(g/dL) / RBC(million/µL) × 10; MCHC (g/dL) = Hgb(g/dL) / Hct(%) × 100
The inputs explained
| Field | What to enter |
|---|---|
| Haemoglobin (g/dL) | A number, measured in g/dL. Starts at 15. |
| Red blood cell count (million/µL) | A number, measured in million/µL. Starts at 5. |
| Haematocrit (%) | A number, measured in %. Starts at 45. |
Worked examples
Every figure in the tables below is produced by this page’s own calculator at build time, so the numbers and the tool always agree. Select any row to load that scenario.
How the answer changes with haemoglobin
Every other input is held at the calculator’s starting values while haemoglobin varies. Select any row to load that scenario into the calculator.
