MCH (Mean Corpuscular Hemoglobin)
MCH is the average amount of hemoglobin inside each red blood cell. It tracks closely with MCV: smaller cells carry less hemoglobin, larger cells carry more.
Your reading
This app uses 27–33 picograms. A low MCH usually goes with iron deficiency. A high MCH usually goes with large cells from low B12 or folate. On its own, MCH rarely tells you more than MCV and hemoglobin already do.
What may help
- —Reading it together with MCV and ferritin rather than on its own
- —Iron, B12 and folate from food or supplements, depending on which direction it's off
When to talk to a doctor
If it's off together with low hemoglobin or an abnormal MCV, which together suggest anemia worth investigating.
Common questions
What is MCH?

What is a normal MCH level?
Daygo uses 27–33 pg as the reference range. This app uses 27–33 picograms. A low MCH usually goes with iron deficiency. A high MCH usually goes with large cells from low B12 or folate. On its own, MCH rarely tells you more than MCV and hemoglobin already do.
How can I improve my MCH?
Reading it together with MCV and ferritin rather than on its own. Iron, B12 and folate from food or supplements, depending on which direction it's off.
When should I see a doctor about MCH?
