Mean hemoglobin mass of red blood cell (MCH)

MCH is usually measured as a part of blood count and is used to help diagnose anemia.

Mean red blood cell hemoglobin mass (MCH)

  • MCH value shows the amount of hemoglobin contained in one red blood cell. 
  • MCH test is used to help diagnose anemia.
  • Most common symptoms of iron deficiency anemia are fatigue and impaired physical.

What is mean red blood cell hemoglobin mass (MCH)?

MCH value shows the amount of hemoglobin contained in one red blood cell. Hemoglobin is a blood protein. Hemoglobin transports oxygen in the body. In anemia, the level of hemoglobin in the blood is lower than normal. 

MCH is usually measured as a part of blood count and is used to help diagnose anemia. 

Reference values for MCH

Reference value for MCH for both (adult) women and men is 27–33%. 

Reference levels may vary depending on the laboratory and the test analysis method.

Low MCH value

Low MCH is usually a sign of microcytic anemia. In microcytic anemia, the red blood cells are too small and cannot carry as much hemoglobin as they should. 

Iron deficiency anemia is the most common type of microcytic anemia and can be caused, for example, by prolonged blood loss due to heavy menstruation or intestinal bleeding. 

MCH may also be lower than normal in hypochromic anemia. In this type of anemia, hemoglobin level is reduced proportionally more than the red blood cell count

High MCH value

High MCH value is usually a sign of macrocytic anemia. This condition occurs when the blood cells are too large due to factors such as a vitamin B12 or folate deficiency. 

A high MCH may also be due to the following factors: 

FAQ

If the platelet count is too high, it is important to identify and treat the underlying causes of this condition. Common ways to manage platelet count include hydration and the use of blood thinners such as aspirin as directed by a doctor. In some cases, other medications or treatments may be used, such as blood thinners or treatments aimed at improving blood circulation. It is important to discuss with a doctor before starting any treatment.

An adult human has an average of about five liters of blood. The amount of blood can vary individually and is about 7-8% of a person’s total body weight. For example, a person weighing 70 kilograms has about five and a half liters of blood. The amount of blood is important as it transports oxygen and nutrients to different parts of the body and helps remove waste products.

Red blood cells live for an average of 120 days in the human body. After this, they are primarily broken down in the spleen, where their iron is salvaged and used to produce new red blood cells. The lifespan of red blood cells can vary among different people and under different conditions, but 120 days is a generally accepted average.

The treatment of macrocytosis typically focuses on addressing the underlying cause. If macrocytosis is due to a deficiency in vitamin B12 or folate, treatment includes supplementing these vitamins. If it is related to alcohol use, reducing or stopping alcohol consumption is recommended. The doctor may also prescribe other treatments depending on the cause of the macrocytosis.

The rate of decrease in MCV (mean corpuscular volume) depends on what has caused the change. For example, in the treatment of iron deficiency, MCV can start to decrease within a few weeks of starting iron supplementation. If the change in MCV is due to other health-related causes, such as vitamin deficiencies or bone marrow diseases, the rate of decrease can vary.

A complete blood count is usually taken when there is a desire to get a comprehensive picture of a person’s general health status or when there is a need to monitor certain health-related changes. A complete blood count can help identify various conditions, such as anemia.
