MCH stands for Mean Corpuscular Hemoglobin. It is a measurement used in blood tests to determine the average amount of hemoglobin contained within a single red blood cell. Hemoglobin is the protein responsible for carrying oxygen from the lungs to the rest of the body.
Why MCH Matters
Measuring MCH helps doctors assess the quality and function of red blood cells. It provides insight into different types of anaemia and other blood disorders. Abnormal MCH values can indicate issues with hemoglobin production or red blood cell size.
Interpreting MCH Results
Normal MCH values typically range from about 27 to 33 picograms per cell, although this can vary slightly depending on the laboratory. A low MCH value may suggest microcytic anaemia, where red blood cells are smaller and carry less hemoglobin, often due to iron deficiency. A high MCH value might indicate macrocytic anaemia, where red blood cells are larger, which can be caused by vitamin B12 or folate deficiencies.
Summary
MCH is a blood test measurement that shows the average hemoglobin amount in red blood cells. It helps diagnose different anaemia types and guide appropriate treatment.
