The normal range for Mean Corpuscular Hemoglobin (MCH) in adults is generally considered to be 27 to 31 picograms (pg) per cell. However, it's important to remember that these values can vary slightly depending on the specific laboratory and the machine used for testing.
Here's a more detailed breakdown:
-
What MCH Measures: MCH reflects the average amount of hemoglobin within a single red blood cell. Hemoglobin is the protein in red blood cells responsible for carrying oxygen.
-
Normal MCH Range (Adults): 27 - 31 pg/cell
-
Important Considerations:
- Laboratory Variation: Different labs may use slightly different methods and reference ranges. Always refer to the reference range provided on your specific lab report.
- Age: MCH values can be different in young children compared to adults.
- Medical History: Your doctor will consider your overall health and medical history when interpreting your MCH results.
-
What does it mean if my MCH is outside the normal range?
- Low MCH (Hypochromia): An MCH below 27 pg/cell may indicate iron deficiency anemia, thalassemia, or other conditions affecting hemoglobin production.
- High MCH (Hyperchromia): An MCH above 31 pg/cell can be seen in macrocytic anemias (e.g., vitamin B12 or folate deficiency), liver disease, or alcoholism.
