What does a low MCHC in a blood test mean?

MCHC means Mean Corpuscular Hemoglobin Concentration. It is measured in g/dl and indicates that the amount of hemoglobin per unit volume is lower than normal.

A low MCHC level is usually a sign of iron-deficiency anemia. A low MCHC is caused in more than 95% of cases by this condition.

However, it is not very specific because only in 20% of the people with iron-deficiency anemia there is a MCHC level below the normal range. For the diagnosis of iron-deficiency anemia, it is better to study other more specific parameters such as hemoglobin, MCV, RDW, serum iron, ferritin or transferrin.

A low MCHC level in the blood means:

  • Mild MCHC decrease (29 - 32 g/dl in adults):

    A mild MCHC decrease is typical of iron-deficiency anemia when there is a mild anemia and hemoglobin level is around 9 or 10 g/dl.

  • Moderate MCHC decrease (25 - 29 g/dl in adults):

    A mild MCHC decrease is typical of iron-deficiency anemia when there is a severe anemia and hemoglobin level is very low.

  • Severe MCHC decrease (< 25 g/dl in adults):

    A severe MCHC decrease below 25g/dl are not very common and it may be due to a serious iron-deficiency anemia.

Which factors can reduce the MCHC?

Some circumstances may reduce your MCHC:

  • Lead poisoning

Which diseases can reduce your MCHC?

A lower than normal MCHC may be due to:

  • Iron-deficiency anemia

    What can I do to increase the MCHC level in the blood?

    In most cases, a low MHCH level is due to iron-deficiency anemia. Therefore, an adequate iron intake is necessary.

    The following foods are rich in iron:

    • Red meat (pork, beef)
    • Seafood (clams, cockles, mussels)
    • Vegetables (spinach, chard)
    • Legumes (lentils, beans, chickpeas)

    If diet is not enough, your doctor may prescribe you iron supplements.

    IMPORTANT: These levels are expressed in g/dl. They are an example of a healthy woman of about 45 years old with no known disease and not taking any medication. The ranges can be different depending on the laboratory or on your personal circumstances.
