You Pet's Mean Corpuscular Hemoglobin = MCH = The Amount Of Hemoglobin In Your Pet's Individual Red Blood Cells

This blood test tells your veterinarian the average amount of hemoglobin in each of your pet’s red blood cells. It is calculated from your pet’s hemoglobin level and red blood cell numbers. It is still included in your pet’s bloodwork results; but when the reading is abnormal, it tells your veterinarian very little, other than that your pets hemoglobin level and red blood cell count were abnormal – something he already knew.



Tests called MCHC (the amount of hemoglobin per volume within the red cell) and MCV (the size of your pet's red blood cells) give your vet considerably more information in sorting out anemia problems. Read about them by following the links.

Asiatic Dogs

Dog breeds that originate in Asia can have naturally low MCV, MCH and high end RBC (erythrocyte) numbers. Not all do. They can also be mistaken for husky and arctic breed crosses that do not share this natural peculiarity. Asian breeds can also have higher blood potassium levels. None of these features seem to affect their health. (ref1, ref2, ref3)
