Mean Corpuscular Hemoglobin Concentration: What Your Results Mean
Bottom line: MCHC measures hemoglobin concentration in red blood cells. Normal is 32-36 g/dL. Abnormal values point to specific anemia types.
What Is Mean Corpuscular Hemoglobin Concentration (MCHC)?
Mean Corpuscular Hemoglobin Concentration (MCHC) is a laboratory test that measures the average concentration of hemoglobin inside a single red blood cell. Hemoglobin is the protein within red blood cells responsible for carrying oxygen from your lungs to the rest of your body. This test helps your doctor understand how well your red blood cells are filled with hemoglobin, which is crucial for delivering adequate oxygen throughout your system.
A low MCHC can indicate that your red blood cells are not adequately saturated with hemoglobin. This might be due to insufficient iron in your body, which is a key component needed to produce hemoglobin. Conversely, a high MCHC suggests that your red blood cells are more densely packed with hemoglobin than usual. Understanding your MCHC level provides valuable insight into the health and functionality of your red blood cells and can help diagnose and monitor various types of anemia and other blood disorders.
Mean Corpuscular Hemoglobin Concentration (MCHC) Reference Ranges
| Classification | Range (g/dL) |
|---|---|
| Very Low | < 32 |
| Low | 32 - 34 |
| Normal | 34 - 36 |
| High | 36 - 38 |
| Very High | > 38 |
What Affects Your Mean Corpuscular Hemoglobin Concentration (MCHC) Levels?
- Iron deficiency anemia
- Vitamin B12 deficiency
- Folate deficiency
- Hemolytic anemia
- Liver disease
- Certain genetic disorders affecting hemoglobin production
- Dehydration
- Recent blood transfusion
When to Get Tested
Your doctor may order an MCHC test as part of a complete blood count (CBC) panel. This is often done when you present with symptoms suggestive of anemia, such as fatigue, weakness, pale skin, shortness of breath, or dizziness. It's also commonly ordered as part of a routine physical examination or to monitor patients with known blood disorders or conditions that can affect red blood cell production or survival.

Frequently Asked Questions
A low MCHC typically indicates that your red blood cells are not containing enough hemoglobin. This is most commonly seen in iron deficiency anemia, where there isn't enough iron to produce sufficient hemoglobin. Other causes can include certain types of anemia related to vitamin deficiencies or chronic diseases.
A high MCHC suggests that your red blood cells are more concentrated with hemoglobin than normal. This finding is less common than a low MCHC. Potential causes include hereditary spherocytosis, a condition where red blood cells are abnormally shaped and smaller but more concentrated with hemoglobin, or certain other inherited conditions affecting red blood cell membranes.
MCHC is one of several red blood cell indices measured in a CBC. It works alongside Mean Corpuscular Volume (MCV), which measures the average size of red blood cells, and Mean Corpuscular Hemoglobin (MCH), which measures the average amount of hemoglobin per red blood cell, to provide a comprehensive picture of red blood cell health and function.
