CMV, which means Medium Corpuscular Volume, is an index found in the blood formula that indicates the average size of red blood cells, which are red blood cells.The normal value of the VCM is between 80 and 100 fl, and may vary by laboratory.
Knowing the amount of CMV is especially important to help diagnose anemia and track the patient after starting treatment, however, CMV testing should be done at the same time as testing the entire blood formula, mainly HCM, RDW and hemoglobin.how to interpret the blood formula.
- The average corpuscular volume can be increased or decreased.
- Each of which is characteristic of different health problems:.
A high CMV indicates that red blood cells are large, with an increased value of RDW, a situation known as anisocytosis, usually verified.Find out what RDW means in your blood test.
The increased value may be indicative of megaloblastic anemia and pernicious anemia, for example, but it can also be altered in alcohol dependence, bleeding, myelodysplastic syndromes and hypothyroidism.
A weak CMV indicates that red blood cells in the blood are small, called microcytics.Microcytic red blood cells can be found in several situations, such as minor thalassemia, congenital spherocytosis, uremia, chronic infections, and especially ferroprivas anemias, also known as hypochromics.microcytic anemia, as they also have low MCH.Understand what MCH is.
For laboratory diagnosis of anemia, your doctor primarily checks hemoglobin values in addition to other clues, such as CMV and HCM. If hemoglobin is low, the type of anemia can be identified from the following results:
Depending on the result of the blood formula, your doctor may order more tests that can confirm your diagnosis of anemia.See what tests confirm anemia.
