A low MCHC (Mean Corpuscular Hemoglobin Concentration) in a blood test indicates that red blood cells do not have enough hemoglobin, which can lead to symptoms such as fatigue, weakness, or shortness of breath.
According to multiple sources, including [1], [2], and [3], a low MCHC is defined as a value below the normal range of 32-36 grams per deciliter (320-360 grams per liter). This condition is known as hypochromia. The causes of low MCHC are not explicitly stated in the search results, but it is mentioned that it can signal a problem with the red blood cells.
There is no urgent medical concern associated with a low MCHC. However, if you are experiencing symptoms such as fatigue, weakness, or shortness of breath, it is recommended to consult with a healthcare professional for proper evaluation and treatment.
While the normal range of MCHC is between 32 and 36 grams per deciliter, or 320 to 360 grams per liter, values below this range can indicate low MCHC, and this condition is known as hypochromia.
When blood test results show low MCHC, it's natural to feel concerned and want answers quickly. MCHC, or mean corpuscular hemoglobin concentration, measures
Medically reviewed by Avi Varma, MD, MPH, AAHIVS, FAAFP — Written by Peter Morales-Brown — Updated on January 9, 2026 · A low mean corpuscular hemoglobin concentration (MCHC) means red blood cells do not have enough hemoglobin.
Hemoglobin carries oxygen. When your red blood cells don’t have enough of it, your tissues may not get the oxygen they need. This can lead to symptoms like fatigue, weakness, or shortness of breath. But symptoms vary, and some people feel nothing at all. Low MCHC isn’t a diagnosis.
An MCHC blood test measures the amount of hemoglobin a red blood cell has relative to the size of the cell. A level too high or low can signal a problem.
**What does abnormal MCHC mean?** Mean corpuscular hemoglobin concentration (MCHC) measures hemoglobin density in red blood cells, with a normal range of **32 to 36 g/dL**. - **Low MCHC** most commonly indicates **iron deficiency anemia**. - **High ...
Your MCH level is the average amount of hemoglobin in a single blood cell. But your MCHC level is the average concentration of hemoglobin in a given volume of red cells. MCH “does not take into account red cell volume, whereas MCHC does," said Jahnavi Gollamudi, MD, an assistant professor at the University of Cincinnati College of Medicine.
A **low MCHC** most often points to iron deficiency anemia. A **high MCHC** is less common and may indicate hemolysis from conditions like hereditary spherocytosis or autoimmune hemolytic anemia, dehydration, or a lab artifact.
