Mean Corpuscular Hemoglobin

The Mean Corpuscular Hemoglobin test helps measure the amount of hemoglobin in the red blood cells (RBCs). This test is a key indicator of how effectively oxygen is being distributed throughout the body. It is often done as part of a complete blood count test that also measures other types of blood cells.

The average amount of hemoglobin in each RBC is calculated by dividing the total amount of hemoglobin in your blood by the number of RBCs present, multiplied by 100. Low or high levels of Mean Corpuscular Hemoglobin (MCH) may indicate an underlying health condition, such as anemia or a vitamin deficiency. 

Your doctor may suggest the Mean Corpuscular Hemoglobin test if you experience symptoms of low MCH levels, such as shortness of breath, loss of regular stamina, consistent tiredness, dizziness, weakness in the body, etc., or those of high MCH levels, such as loss of appetite, brittle nails, fast heartbeat, diarrhea, pale skin, poor concentration, etc. The low levels may indicate iron-deficiency anemia or thalassemia, whereas the high levels may indicate macrocytic anemia. No special preparation is required for an MCH test; you can eat or drink as per your daily routine. 

Test result ranges are approximate and may differ slightly between different labs depending on the methodology and laboratory guidelines. Talk to your doctor about your specific results. The results will help them determine your medical condition and formulate an overall treatment plan.
