Red blood cells are the most abundant type of blood cell. They carry oxygen through the body from the lungs to the tissues. A low red blood cell count is called anemia. There are several ways to classify anemia. One way is by the size of individual red blood cells. Macrocytic anemia refers to large red blood cells that are few in number.

The red blood cell (RBC) count is used to measure the number of oxygen-carrying blood cells in a volume of blood. It is one of the key measures we use to determine how much oxygen is being transported to cells of the body.

Red blood cell (RBC) indices are part of the complete blood count (CBC) test. They are used to help diagnose the cause of anemia, a condition in which there are too few red blood cells. The indices include: Average red blood cell size (MCV) Hemoglobin amount per red blood cell (MCH)

When judging red cell size on a blood smear, the classic rule of thumb is to compare them to the nucleus of a small normal lymphocyte. The normal lymphocyte nucleus has an approximate diameter of 8 µm. Of course this method is not foolproof, as red cells that have less than the normal hemoglobin content tend to flatten out more on a slide and ...

MCV blood test is part of RBC indices (red blood cell indices) and checks the mean corpuscular volume of your blood cells to help doctors check the health of your blood. The MCV blood test shows the average size of your red blood cells. Red blood cells (RBCs) play an important function in transporting oxygen and nutrients to tissue.

The size of red blood cells usually falls within a range of 6 to 8 micrometers in random blood samples that have been analyzed by laboratory testing. Mature forms of the red blood cells (RBCs) are called erythrocytes, which constitute around 40 to 45% of human red blood cells.

A red blood cell (RBC) count is typically ordered as part of a complete blood count (CBC) and may be used as part of a health checkup to screen for a variety of conditions. This test may also be used to help diagnose and/or monitor a number of diseases that affect the production or lifespan of red blood cells.
