MCV

Description

"Mean Corpuscular Volume" (MCV) test measures the average size of your red blood cells to help diagnose different types of anemia. This test is a standard part of a complete blood count (CBC) and is often ordered when fatigue, weakness, or pallor are present. Low MCV suggests microcytic anemia, commonly from iron deficiency, while high values may indicate vitamin B12 or folate deficiency. Results assist doctors in identifying the cause and selecting the right treatment to restore blood health.

Hematology Group, Blood Count Basic Group

Test Group Description

Blood Count Basic Group: This group includes essential tests for evaluating blood cell counts, providing foundational information for assessing overall blood health, and detecting potential abnormalities. Hematology Group: Tests within this group focus on evaluating various aspects of blood health and function. These assessments provide insights into red blood cells, white blood cells, platelets, and other components of the blood.

Optimal Range

For All Individuals:

  • Conventional Unit: 85.00–90.00 fL

  • SI Unit: 85.00–90.00 fL

Normal Range

For All Individuals:

  • Conventional Unit: 79.4–94.8 fL

  • SI Unit: 79.4–94.8 fL

Results That Differ From The Norm (Direct and Indirect Causes)

Increased levels may indicate:


  • Alcoholism

  • Alcohol-related liver disease

  • Anemia of chronic disease

  • Folate deficiency (lack of folic acid)

  • Hemolytic anemia (increased destruction of red blood cells)

  • Hypothyroidism (underactive thyroid)

  • Liver cirrhosis

  • Macro...

Key Reasons For Testing

  • Anemia Diagnosis: Assesses red blood cell size to classify anemia as microcytic, normocytic, or macrocytic.

  • Iron Deficiency Anemia: Identifies low MCV levels indicating microcytic anemia.

  • Vitamin B12 or Folate Deficiency: Detects elevated MCV levels in macrocytic anemia.

  • Thalassemia: Screens for microcytic anemia due to genetic hemoglobin disorders.

  • Response to Treatment: Monitors red blood cell size changes during anemia therapy.

Important Note

Any medical procedure yielding results outside the norm may be directly or indirectly linked to the conditions outlined on this page. Various factors, including genetics, medication and supplement usage, recent illnesses, pregnancy, pre-test eating, smoking, and stress, can impact the test's outcome. Additionally, factors like false positives, false negatives, inaccurate analyses, and others can influence results.


Reference ranges, which help healthcare professionals interpret medical tests, may vary depending on age, gender, and other factors. They may also differ between laboratories due to variations in instruments and methods used. Optimal ranges are designed for preventive purposes, aiming to identify trends and potential risks early, while normal ranges reflect conventional laboratory values indicating no current disease or pathology. Your healthcare practitioner may have specific reasons for testing that deviate from the usual or may interpret results differently based on individual circumstances. Proper interpretation typically involves considering clinical findings and other diagnostic tests. Hence, it is crucial to provide your healthcare professionals with a comprehensive medical history, consult with them for result interpretation, and follow their guidance for potential re-testing or additional diagnostics.
