What Is MCHC Used For?

Doctors use MCHC to assess whether your red blood cells are carrying enough oxygen. It can help identify types of anemia, such as microcytic (small cells) or normocytic (normal-sized cells) anemia, or conditions like hemolysis (destruction of red blood cells).

How Is This Test Performed?

A small blood sample is drawn from a vein, typically in your arm. The blood is then analyzed in a lab to measure the concentration of hemoglobin within each red blood cell. No special preparation is needed, but fasting may be advised depending on your test order.

Possible Results and Their Meaning

Results may be reported as below, at, or above a reference range. Low MCHC can suggest conditions like iron deficiency anemia, thalassemia, or certain liver diseases. High MCHC may indicate conditions such as hereditary spherocytosis or severe dehydration.

Common Conditions Affecting MCHC

Changes in MCHC are often linked to underlying health issues. For example, low levels can be due to insufficient iron, vitamin B12, or folate, while high levels may result from chronic diseases or fluid imbalances.

Reference range

Frequently asked questions

Why might my doctor order this test?
Your doctor may order an MCHC test if they suspect anemia, evaluate symptoms like fatigue, pale skin, or shortness of breath, or investigate unexplained blood abnormalities found during other tests.
What are the typical reference ranges?
Reference ranges can vary by lab and may not be universally standardized. Your results will be compared to ranges specific to your lab and demographic. Always discuss your results with your healthcare provider.
Can I prepare for this test?
Most often, no special preparation is needed. However, if your doctor has specific instructions, follow them carefully. For example, fasting may be required for some related blood tests.
