MCHC (Mean Corpuscular Hemoglobin Concentration) is the concentration of hemoglobin within red blood cells.
- Normal range (adults)
- 32–36 g/dL (320–360 g/L)
- Sample
- Blood
- Fasting
- Not usually needed
- Also called
- Mean Corpuscular Hemoglobin Concentration, M.C.H.C, Mean Cell Hemoglobin Concentration
MCHC normal range
| Group | g/dLConventional units: US, South Asia | g/LSI units: UK, Europe, Australia, international |
|---|---|---|
| Adults | 32–36 | 320–360 |
Your report may use either unit system; labs in the Gulf often print both. Ranges also vary slightly between laboratories, so the range printed on your own report is the one to go by.
Why is the MCHC test done?
It is part of the Complete Blood Count and helps classify anemia.
What does a high MCHC level mean?
A truly high MCHC is uncommon. It is often a lab artefact, or a sign of hereditary spherocytosis or red-cell breakdown.
Common causes
- Sample problems such as clumping or high fat in the blood
- Hereditary spherocytosis
- Hemolysis (red-cell breakdown)
- Severe burns
Diet and lifestyle tips
- No specific diet changes; ask for a repeat test if other results are normal
- Stay well hydrated
What does a low MCHC level mean?
A low MCHC means red cells contain less hemoglobin than normal and look pale under the microscope.
Common causes
- Iron deficiency anemia
- Thalassemia trait
- Long-term blood loss
Diet and lifestyle tips
- Iron-rich foods with vitamin C
- Avoid tea and coffee with meals
When should you see a doctor?
Ask your doctor to review an abnormal MCHC alongside your hemoglobin and MCV.
