What Does MCV Measure?

The MCV provides a snapshot of the size of your red blood cells. While MCV alone isn’t diagnostic, it’s often used alongside other blood tests to identify potential blood disorders, such as anemia caused by deficiencies (e.g., iron, vitamin B12) or certain genetic conditions.

Why Is MCV Tested?

Doctors may order an MCV test if you have symptoms like fatigue, pale skin, shortness of breath, or unusual weakness. It’s also part of routine blood checks for people with known risk factors for blood disorders.

How Is This Test Performed?

A small blood sample is drawn from your arm. The blood is analyzed automatically to measure the average size of your red blood cells and other blood cell counts.

What Are Common Results?

Results are typically reported as a numerical value (e.g., femtoliters per red blood cell), but exact ranges can vary by lab. Abnormal MCV levels may prompt further testing to explore underlying causes.

Reference range

Adult: 80-100 fLN/A

Specimen: whole-blood

No special preparation usually required. Stay well hydrated. Inform your healthcare provider of all medications and supplements you are taking.

Frequently asked questions

Why might my doctor ask for this test?
Your doctor may order this test to check for blood disorders, monitor symptoms like fatigue or pale skin, or as part of a routine health assessment if you have risk factors (e.g., poor diet, chronic illness).
What does an abnormal MCV result mean?
An abnormal MCV doesn’t give a direct diagnosis, but it may signal a need for further tests (like iron studies, vitamin levels, or genetic screening). Your doctor will discuss results and next steps with you.
How often should I get this test?
Frequency depends on your health status. Doctors may recommend periodic testing if you have conditions like anemia, liver disease, or if you’re taking medications that affect blood cells.
