The mean corpuscular hemoglobin , or “mean cell hemoglobin” (MCH), is the average mass of hemoglobin (Hb) per red blood cell (RBC) in a sample of blood. It is reported as part of a standard complete blood count. MCH value is diminished in hypochromic anemias.
Why Get Tested:
- It is done as part of blood indices.
- It is done to diagnose anemia.
When to get Tested:
- when you have signs and symptoms of anemia (weakness, fatigue).
- when you have signs and symptoms of polycythemia (dizziness, headache)
- At regular intervals to monitor a disorder that affects RBCs and to evaluate the effectiveness of treatment
- The best sample is EDTA blood.
- Stable 6 hours at 25 °C and 24 hours at 4 °C.
- Fetal blood collected percutaneous from the umbilical area.
|MCH||26 – 32 pg||26 – 32 pg|

Increased MCH is seen in:
- Macrocytic anemia and in newborn.
Decreased MCH is seen in:
- Microcytic anemia.
- Hypochromic anemia.
