MCV, or mean corpuscular volume, is a measurement of the average size of your red blood cells, which are responsible for carrying oxygen throughout your body. It is calculated during a routine blood test called a complete blood count (CBC).
The MCV test is a valuable tool for diagnosing anemia, a condition where your blood doesn't carry enough oxygen. When the MCV value is outside the normal range, it can indicate various underlying health conditions, including:
- High MCV: This could indicate macrocytic anemia, where red blood cells are larger than normal. This type of anemia can be caused by vitamin B12 or folate deficiency, liver disease, or certain medications.
- Low MCV: This could indicate microcytic anemia, where red blood cells are smaller than normal. This type of anemia can be caused by iron deficiency, thalassemia, or lead poisoning.
The MCV test is usually performed as part of a complete blood count (CBC). This means that it is typically ordered by a healthcare provider as part of a routine checkup or to investigate any symptoms you might be experiencing.
