Mean Corpuscular Hemoglobin Concentration Normal Ranges
MCHC measures the average concentration of hemoglobin in red blood cells as g/dL.
| Age Group | Reference Range | Unit | Notes |
|---|---|---|---|
| Adults (18–64) | 31.5 – 36 | g/dL | — |
Also reported in: %.
Why Doctors Order the Mean Corpuscular Hemoglobin Concentration Test
MCHC is primarily used to detect true hypochromia (low MCHC in severe iron deficiency) and to identify hereditary spherocytosis, where MCHC is paradoxically elevated because spherical cells have a smaller surface-to-volume ratio.
How to Enter Your MCHC Result
Mean Corpuscular Hemoglobin Concentration can be reported in g/dL or %. Choose the unit printed next to your result on the lab report so it is compared with the matching reference range.
What a Low or High MCHC Can Be Associated With
Below the reference range
- Severe iron deficiency anemia
- Thalassemia major
Above the reference range
- Hereditary spherocytosis
- Sample hemolysis (most common — artifact)
- Cold agglutinins (artifact)
- Severe lipemia (artifact)
These are common associations, not a diagnosis. A single result is read alongside your symptoms, history and other tests — discuss it with your doctor.
What Can Change Your MCHC Result
Before you read too much into a result, consider whether any of these applied:
- Sample hemolysis (falsely raises MCHC — most common cause of high MCHC)
- Lipemia (interferes with optical hemoglobin measurement)
- Cold agglutinins
Preparing for the test: No preparation required. Calculated automatically from Hgb, RBC, and MCV.
Symptoms That Often Prompt MCHC Testing
- Jaundice (in spherocytosis)
- Splenomegaly
- Fatigue
- Pallor
