Let us understand- what is MCh Blood test. MCH, or Mean Corpuscular Hemoglobin, is a measure indicating the average hemoglobin quantity within each red blood cell, responsible for transporting oxygen from the lungs to the cells through the bloodstream. Deviations in MCH levels, identified through blood testing, may signify various issues, ranging from nutrient deficiencies to chronic diseases.
Conducted as part of a Comprehensive Blood Count (CBC), the MCH blood test assesses blood composition, including hematocrit, white blood cells (WBC), platelets, hemoglobin, and red blood cells (RBC). This test offers an overview of overall health. MCH is derived from the hemoglobin value (Hgb) and the RBC count, calculated by dividing Hgb by RCB. The normal MCH range is between 26 and 33 picograms (pg) of hemoglobin per RBC.

What do MCH levels signify (Understanding What is MCh Blood Test)?

Your doctor may discuss MCH levels and what is MCh blood Test when explaining certain blood test results. MCH stands for "mean corpuscular hemoglobin," indicating the average amount of hemoglobin, a protein that transports oxygen, in each red blood cell.


  • Hemoglobin, a blood protein, facilitates the delivery of oxygen from red blood cells to cells and tissues in the body. While closely related, it's crucial not to mix up MCH levels with MCHC levels.
  • MCH levels signify the average hemoglobin content in each red blood cell, while MCHC levels represent the average hemoglobin weight relative to the volume of red blood cells. Both parameters provide insights into the overall health of hemoglobin in the blood.
  • You might encounter MCH details during a CBC (complete blood count) test, which assesses various components of your blood, including red and white blood cells. Doctors utilize CBC information to compute your MCH. Another related measure is "mean corpuscular hemoglobin concentration" (MCHC), gauging the average hemoglobin amount in a cluster of red blood cells.
  • Both measurements aid in diagnosing anemia, a condition characterized by insufficient healthy red blood cells or impaired functionality. Anemia can lead to extreme fatigue.

What Do MCH and MCHC Represent?

MCH (Mean Corpuscular Hemoglobin) levels gauge the average amount of hemoglobin in each red blood cell, while MCHC blood test (Mean Corpuscular Hemoglobin Concentration) levels measure the average weight of hemoglobin relative to the volume of red blood cells. Both serve as indicators of the health of hemoglobin in the bloodstream. Hemoglobin, a crucial blood protein, facilitates the transport of oxygen to the body's cells and tissues through red blood cells. MCH measures the quantity of hemoglobin in a red blood cell, while the MCHC blood test value signifies the amount of hemoglobin per unit volume.


MCHC Blood Test Explained


  • The MCHC blood test, denoting Mean Corpuscular Hemoglobin Concentration, assesses the average concentration of hemoglobin in an individual red blood cell.
  • In a blood test, the complete form of MCHC is Mean Corpuscular Hemoglobin Concentration. This test determines the quantity of hemoglobin within a red blood cell relative to its volume.
  • Crucial for oxygen transport, hemoglobin, a protein in red blood cells, is essential for the body. The MCHC blood test aims to evaluate whether there are any underlying medical conditions by measuring the average hemoglobin concentration.
  • An abnormal MCHC level, either too low or too high, can indicate various health conditions. Notably, MCHC serves as a key metric in diagnosing anemia, a condition characterized by insufficient red blood cell levels, leading to symptoms like weakness or fatigue.

This blog will delve into the meaning of MCHC in blood tests, elucidate the causes of high MCHC, and unravel the implications of low MCHC levels.


MCH Levels

Physicians frequently request a complete blood count (CBC) test to determine an individual's MCH levels. In adults, typically MCH blood test normal range varies from approximately 27 to 31 picograms (pg) per cell, although variations can occur depending on the testing machine and 32 to 36 grams per deciliter (g/dL), or 320 to 360 grams per liter (g/L) for MCHC blood test.
For young children, the reference values differ. Low MCH is indicated by concentrations at or below 27 pg per cell, while high MCH levels are defined by concentrations at 34 pg per cell or higher.

What does MCH Blood Test Results Indicate?


  • For understanding what is MCh blood test, MCH blood test evaluates the average hemoglobin content in red blood cells, measured in picograms per red blood cell (pg/cell). MCH blood test normal range typically fall between 27 and 33 picograms per red blood cell, and deviations from this range (MCH blood test normal range) may signal an underlying health issue.
  • Low MCH levels may suggest iron deficiency anemia, a condition where the body lacks sufficient iron for hemoglobin production. Iron deficiency anemia, often stemming from factors like inadequate nutrition, blood loss, or chronic diseases, is the most prevalent type of anemia. Symptoms may encompass fatigue, weakness, shortness of breath, and pale skin, alongside low MCH levels.
  • Conversely, elevated MCH levels from MCH blood test normal range may indicate macrocytic anemia, characterized by the production of larger-than-normal red blood cells containing excess hemoglobin. Factors contributing to macrocytic anemia include deficiencies in vitamin B12 or folic acid, liver disease, and alcoholism. Symptoms might encompass fatigue, weakness, difficulty concentrating, and numbness or tingling in the extremities.
  • It's crucial to recognize that MCH levels offer only partial insight into anemia and blood disorders. Healthcare providers often order additional tests, such as a complete blood count (CBC), for a comprehensive evaluation of blood health. Interpretation of MCH results considers medical history, symptoms, and other relevant factors.

In summary, the answer to what is MCh blood test is that the MCH blood test is a fundamental tool gauging hemoglobin levels in red blood cells, vital for diagnosing and monitoring specific anemias and blood disorders. Typically conducted as part of a complete blood count (CBC), this test aids in identifying underlying health concerns. While comprehending MCH results provides valuable insights into overall health, it's essential to acknowledge that additional testing may be required for a comprehensive understanding of blood health. Overall, the MCH blood test and MCH blood test normal range remains a valuable asset for preserving and enhancing overall health and well-being.
