A high MCHC means the measured concentration of hemoglobin inside red blood cells is above the lab's reference range. It can appear with some types of red blood cell breakdown or inherited red blood cell conditions, but one result cannot diagnose the cause. Ask a clinician to review it with hemoglobin, hematocrit, the rest of the CBC, symptoms, history, and whether repeat testing is needed.
