What Is MCHC in a Blood Test?

Blood tests let doctors know about many possible health conditions 1. The letters and what they mean often mean nothing to those uninitiated into the medical mysteries. MCHC, which stands for mean corpuscular hemoglobin concentration, is one of the many acronyms that come back on medical test results that confuse the patient but are meaningful to the doctor.


This identifier in a blood test can help a doctor diagnose a patient with anemia. Patients whose levels fall within the normal ranges do not need to worry about having anemia. A low MCHC count alone does not give a medical professional enough information to make a specific diagnosis.

MHCH is measured in grams per deciliter (a deciliter is one tenth of a liter). The normal range value for this is 31 to 35 grams per deciliter.

Treating Anemia

The doctor will use these numbers to help determine what kind of anemia a patient suffers from. Iron deficiency is the most common cause, and a change in diet should cause the blood to return to its normal state within a couple of weeks once the iron levels have been replenished 2.

Other causes require different treatment, and a physician will prescribe the proper course of action in his patient to cause the MCHC and MCV counts to return to normal levels.
