The MCV blood test is designed to calculate red blood cell size, also known as Mean Corpuscular Volume. There are values for the test that are considered normal, and, in general, if your results fall within these values, your test results will show a relatively normal count or size. However, if your results are outside the normal values, there may be problems like blood disorders to worry about.
An MCV blood test is especially valuable if your physician is having trouble isolating a problem you may be having physically, but which is not causing any other signs. The anomalies in the size of red blood cells can cause anemia, if your body is deficient in vitamin B12. If the size is too small, you may have other problems.
Successfully interpreting your blood work is an important task for your physician. In the MCV blood test, your doctor will be looking for the results of the hematocrit, which is the percentage of the volume of your blood that is red blood cells. This is a valuable way to determine whether you have an ailment without clear symptoms.
Red blood cells are important for the good health of your body. They take oxygen from your lungs and carry it throughout your entire body. Hemoglobin itself is important in this internal transportation. If you have a low red blood cell count, you may be suffering from anemia. A deficiency in folic acid may cause a higher MCV value. There are different types of anemia, and, actually, high or low red blood cell count may be indicative of anemia, of various types.
In addition to the MCV blood test, you may have other tests performed, like a “red blood cell distribution width”. These tests will measure the concentration and amount of hemoglobin within each average cell. High or low values will lead your doctor toward a diagnosis of anemia, the type of which depends on whether you are above or below the normal range.
You can check with your physician about your MCV blood test readings, to see if they are in the normal range. Have your doctor explain the tests and results to you. Make sure he has a clear plan to bring your results back to normal. He may wish you to have regularly scheduled blood work done, to check for improvement.
