Mean Corpuscular Hemoglobin Normal Ranges
MCH measures the average amount of hemoglobin contained in a single red blood cell, expressed in picograms (pg).
| Age Group | Reference Range | Unit | Notes |
|---|---|---|---|
| Adults (18–64) | 27 – 33 | pg | — |
Why Doctors Order the Mean Corpuscular Hemoglobin Test
MCH provides complementary information to MCV in anemia classification. Hypochromic anemia (low MCH) alongside microcytosis (low MCV) strongly suggests iron deficiency.
How to Enter Your MCH Result
Enter your MCH value in pg, exactly as shown on your lab report.
What a Low or High MCH Can Be Associated With
Below the reference range
- Iron deficiency anemia
- Thalassemia
- Anemia of chronic disease
- Lead poisoning
Above the reference range
- Macrocytic anemia (B12 or folate deficiency)
- Hereditary spherocytosis (hyperchromic cells)
- Cold agglutinins (laboratory 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 MCH Result
Before you read too much into a result, consider whether any of these applied:
- Lipemia (high fat content in blood falsely raises measured hemoglobin, raising MCH)
- High WBC count (can affect spectrophotometric hemoglobin measurement)
Preparing for the test: No special preparation. Automatically calculated from CBC parameters.
Symptoms That Often Prompt MCH Testing
- Fatigue
- Pallor
- Weakness
- Shortness of breath on exertion
