The Concentration Test
The Concentration Test
Every red blood cell in your body carries oxygen using haemoglobin, but the concentration of this vital protein matters as much as the total amount. Mean Cell Haemoglobin Concentration (MCHC) measures how densely packed with haemoglobin your red blood cells are—revealing whether your cellular oxygen carriers are optimally loaded or struggling with efficiency.

When Your Cells Are Diluted
Low MCHC indicates that your red blood cells contain insufficient haemoglobin concentration relative to their size—like having delivery trucks with too much empty space and too little cargo. A clinically significant condition, however, rarely occurs in isolation and typically accompanies other blood abnormalities.
The symptoms you might experience—persistent fatigue, weakness, pale skin, shortness of breath, and feeling cold—aren't directly caused by low MCHC alone. These occur because low MCHC usually accompanies iron deficiency anaemia, where reduced haemoglobin production affects your body's overall oxygen-carrying capacity. You might notice decreased stamina or find yourself needing more rest than usual.
Low MCHC can also be associated with chronic inflammatory diseases, and certain inherited blood disorders like thalassemia. However, MCHC provides supporting evidence rather than a standalone diagnosis—it gains clinical significance when interpreted alongside other blood parameters.

When Your Cells Are Over-Concentrated
High MCHC indicates that your red blood cells contain an elevated concentration of haemoglobin relative to their size. This finding is most commonly associated with hereditary spherocytosis, where red blood cells become sphere-shaped. Unlike low MCHC, elevated levels are less frequently encountered and typically signal specific underlying conditions.
Symptoms associated with high MCHC may include fatigue, pale skin, jaundice, or an enlarged spleen, though these symptoms relate to the underlying condition rather than the MCHC elevation itself. In hereditary spherocytosis, the typical pathological signs are anaemia, jaundice, and splenomegaly, with the elevated MCHC serving as a diagnostic marker.

What Affects Your Haemoglobin Concentration?
Several factors influence haemoglobin concentration within red blood cells. Low MCHC most commonly results from iron deficiency, which impairs haemoglobin synthesis and leaves cells with inadequate content. Chronic inflammatory conditions, inherited blood disorders such as thalassemia, and certain nutritional deficiencies can also reduce MCHC levels.
Hereditary spherocytosis, a genetic condition affecting cell membrane structure, commonly causes elevated MCHC. Severe burns, autoimmune conditions targeting red blood cells, significant dehydration, and certain enzyme deficiencies can also increase MCHC.
Certain groups face higher risk for MCHC abnormalities. Women with heavy menstrual periods may develop iron deficiency leading to low MCHC. Those with family history of blood disorders, particularly conditions causing gallstones or recurrent anaemia, may carry genetic predispositions to MCHC abnormalities. Additionally, chronic inflammatory conditions, autoimmune diseases, and occupational lead exposure can influence MCHC levels.

Understanding Your Results
MCHC is measured in grams per liter (g/L):
Normal range: 320-360 g/L
Hypochromic (under-concentrated): Below 320 g/L
Hyperchromic (over-concentrated): Above 360 g/L
This test is part of a full blood count (FBC) and works with other red blood cell measurements to identify specific types of anemia and blood disorders.
MCHC never provides a complete diagnostic picture on its own. It's most valuable when combined with other red blood cell indices, particularly Mean Cell Volume (MCV) and haemoglobin levels. For instance, low MCHC with low MCV typically suggests iron deficiency, while high MCHC with spherical cell appearance on blood film might indicate spherocytosis.
MCHC helps characterise the type of blood disorder present but requires comprehensive evaluation for proper interpretation.

The Takeaway
MCHC reveals whether your red blood cells contain optimal haemoglobin concentration for efficient oxygen transport, but it's always part of a broader haematological assessment. Properly concentrated cells contribute to effective oxygen delivery throughout your body, while abnormal concentrations often signal specific underlying conditions requiring different approaches.
Most conditions associated with MCHC abnormalities can be effectively managed when the underlying cause is identified and addressed. However, MCHC serves as a supporting diagnostic tool rather than a standalone indicator—it provides valuable information when combined with other blood test results and clinical findings.
Don't ignore persistent fatigue, especially if accompanied by a family history of blood disorders. A simple blood test can reveal whether your red blood cells are properly concentrated to meet your body's oxygen needs.
