MCH stands for Mean Corpuscular Hemoglobin, which is a way to check how much hemoglobin is in your red blood cells. Hemoglobin is the part of the blood that carries oxygen, which our bodies need to be strong and healthy.
If someone has MCH levels that are moderately low, it means that the amount of hemoglobin in their red blood cells is a bit less than normal. This could mean that they might not be getting enough oxygen, which can sometimes make them feel tired or weak. It's important to talk to a doctor to find out why this is happening and if anything needs to be done to help.
