Medical Q&As


I recently had a blood test which revealed that my MCH was raised at 38%, which I was told was high. Is this serious?

MCH stands for mean corpuscular haemoglobin concentration and is a measure of the average amount of haemoglobin in the red blood cells. Haemoglobin binds with oxygen and transports the oxygen throughout the body after it has been absorbed through the lungs. Your test result is only marginally above the upper limit for the range of normal values and means that you have a slightly higher level of haemoglobin in your red blood cells. It is probably not of any significance.
