MCV Auto (RBC)

MCV measures the average size of your red blood cells. It’s a key marker for nutrient status—low MCV often means iron deficiency, while high MCV can indicate low B12 or folate. If your red cells are too big or too small, it means oxygen delivery might be impaired, even if your total RBC count looks okay. A tight MCV is a great signal for efficient energy production and micronutrient balance.
