Average haemoglobin per red cell.
Normal range
Adult reference range.
- Low< 27 pg
- Normal27 – 33 pg
- High≥ 33 pg
What it measures
The average amount of haemoglobin in each red cell. It moves with MCV and helps separate iron deficiency from an inherited small-cell picture.
What moves it
Tracks with MCV and iron status — low in iron deficiency, high in B12 or folate deficiency.
How to bring it into range
Read it with MCV, RDW and ferritin. On its own it adds little.
How fast it responds
Six to twelve weeks.
Also reported as: mean corpuscular hemoglobin

Common questions
- What is the normal MCH range?
- The normal MCH range is 27 – 33 pg for adults. Labs differ a little, so also check the range printed on your report.
- What does a high MCH mean?
- A value above the reference band means MCH is outside the range typical for a healthy adult. A single reading is rarely conclusive on its own — what matters is the trend across draws and the other markers around it, which is why HealthOS reads the whole panel together rather than one number at a time.
- How do I improve my MCH?
- Read it with MCV, RDW and ferritin. On its own it adds little.
