what does mcv small blood cells mean
Typically when we speak about smaller than normal red blood cells, we talk about their volume. Assuming you mean small volume red blood cells (called a low MCV), there are many conditions that can cause this. I recommend that you follow-up with your doctor. The most common is iron deficiency, which is diagnosed not only by looking at blood iron levels but also ferritin, total iron binding capacity and sometimes transferrin saturation.
The normal mean corpuscular volume (abbreviated to MCV on full blood count results) is 80-100 fL, with smaller cells (<80 fL) described as microcytic and larger cells (>100 fL) as macrocytic (the latter occur in macrocytic anemia).The MCV is the average red blood cell size.
