Mean Corpuscular Volume
Understanding Mean Corpuscular Volume
What is Mean Corpuscular Volume?
A Mean Corpuscular Volume test measures the average size of red blood cells (RBCs) in the blood. This test is a key indicator of anemia, several nutritional deficiencies, and other conditions related to RBC size variation. It is often done as part of a complete blood count test that also measures other types of blood cells.
Red blood cells help carry oxygen throughout the body, and their size can be an important indicator of how well they can transport oxygen. A Mean Corpuscular Volume blood test is helpful because having a large number of atypically large or small RBCs can indicate potential health concerns. A high MCV may indicate hypothyroidism, liver disease, aplastic anemia, hemolytic anemia, and reticulocytosis, whereas a low MCV may indicate iron-deficiency anemia or thalassemia.
No special preparation is required before taking an MCV test; eat or drink as per your daily routine. Test result ranges are approximate and may differ slightly between different labs depending on the methodology and laboratory guidelines. Talk to your doctor about your specific test results. The results will help them determine your medical condition and formulate your overall treatment plan.
What is Mean Corpuscular Volume used for?
A Mean Corpuscular Volume test can be done:
-
As part of a complete blood count test to monitor your overall health.
-
To evaluate symptoms suggestive of anemia, such as fatigue, pale skin, and lightheadedness.
-
To identify different types of anemia and other genetic conditions like thalassemia.
-
To monitor and evaluate the effectiveness of the treatment for anemia and other conditions that can affect the size of red blood cells, such as liver disease or hypothyroidism.
-
As an additional test for many medical conditions.
What does Mean Corpuscular Volume measure?
A Mean Corpuscular Volume test measures the average size of your red blood cells, which carry oxygen through your body. This test tells whether your RBCs are uniform or vary significantly in size.
