When the needle goes in or out, you may feel a sting. This usually only takes a few minutes.

Results Interpretations

The normal range for MCV is between 4.3 and 5.5 million cells per cubic millimeter (MCV) , or 80–100 femtoliters.

If your red blood cells are smaller than normal, this could indicate:

  • Iron-deficiency anaemia is one type of anaemia.
  • Sideroblastic anemia.
  • H. pylori infection.
  • Thalassemia.

If your red blood cells are larger than normal, this could be a sign of:

  • Pernicious anaemia is caused by:
    • A vitamin B12 deficiency.
    • A disease that inhibits your body’s to use vitamin B12, including certain autoimmune disorders, celiac disease, or Crohn’s disease.

  • A sudden blood loss
  • Kidney disease
  • Aplastic anaemia (infrequent)

Anemia is a condition in which the number of erythrocytes red blood cells (RBCs) in a person’s blood is low. In order to diagnose anemia, your doctor may require you to undergo a series of tests known as the red blood cell indices. These tests include a complete blood count (CBC) and a mean corpuscular volume (MCV) test. The MCV test is part of a group of tests called the red blood cell indices. The other tests in this group are:

  • Red blood cell count (RBC)
  • Red blood cell differential (RDW)
  • Blood differential (BD)
  • Iron tests
  • B12 level
  • Hemoglobin (hgb)
  • MCHC
  • MCH
  • Hematocrit (HCT).
  • Reticulocyte count
  • Together, these tests help to determine the type of anemia that a person is suffering from.

The MCV blood test is part of a group of blood tests called red blood cell tests, and is helpful in diagnosing conditions such as anemia, folate deficiency, liver disease, hypothyroidism, and increased risk of infection. If you have an abnormal MCV test, your doctor will likely recommend further tests to help diagnose the underlying condition.
