A high MCHC level is anything above 36 percent as the normal range is considered to be from 28 percent to 36 percent, according to Newport Natural Health and Dr. Leigh Connealy, M.D. A MCHC level or "mean corpuscular hemoglobin concentration" is a level that tells how much hemoglobin there is within a red blood cell by providing the average percentage, says Lab Tests Online.
Newport Natural News says that when the MCHC level is high, doctors often look for problems with nutrition and when the MCHC levels are low, the doctors are often looking for anemia in the patient. When measuring the MCHC, doctors will also often measure the RDW or red cell distribution. This calculates the percentage of the cell size variation, states Lab Tests Online.
The MCHC level is a part of the standard CBC blood test, says Newport Natural News. The CBC known as a "complete blood count" is a test that looks at red blood cells, platelets and white blood cells, including the number of cells and the kind of cells in the blood, says WebMD. CBC tests will include other levels, such as the WBW, WBW differential, RBC, HCT, Hgb, MCV, MCH, RDW and MPV. Sometimes doctors will also perform a blood smear test to help diagnose more serious problems, such as blood diseases.
