What is an MCV Blood Test?
The MCV blood test calculates the average volume of red blood cells in femtolitres (fL). It forms part of a complete blood count (CBC), which with the packed cell volume (PCV) test forms a routine test that assesses overall blood health. Red blood cells transport oxygen from the lungs to the body's tissues, and their size provides important clues about potential disorders.
Why is the MCV Test Performed?
- Doctors order this test to:
- Detect or classify different types of anaemia
- Investigate symptoms such as persistent fatigue, weakness, pale skin, shortness of breath, or dizziness
- Evaluate unexplained changes in other blood parameters
- Monitor chronic conditions that may affect red blood cell production
- Support diagnosis in cases of nutritional deficiencies, liver issues, or bone marrow problems
How is the MCV Blood Test Performed?
A small blood sample is collected from a vein in your arm. The area is cleaned, a tourniquet applied to make the vein prominent, and blood drawn into a tube. The sample is analysed in the laboratory using automated equipment. The procedure is quick, typically lasting only a few minutes.
Preparation for the MCV Blood Test
- No special preparation is usually needed, as it is part of a standard CBC. However:
- Inform your doctor about any medications, supplements, or recent illnesses
- Follow any specific instructions if the test is combined with fasting-required panels
Risks and Side Effects
The test is very safe with minimal risks. You may experience:
- Mild discomfort or stinging during the needle insertion
- Slight bruising or tenderness at the site
- Rare light-headedness
- These effects are temporary and resolve quickly.
MCV Normal Range and Interpretation of Results
The MCV normal range for most adults is:
- Results are interpreted alongside other CBC values.
- MCV blood test high (above 100 fL, called macrocytosis) may indicate:
- Vitamin B12 or folate deficiency
- Liver disease
- Excessive alcohol consumption
- Hypothyroidism
- Certain medications
- Bone marrow disorders
- MCV blood test low (below 80 fL, called microcytosis) may suggest:
- Iron deficiency anaemia
- Thalassaemia
- Chronic disease
- Lead poisoning
- Sideroblastic anaemia
- Your doctor will explain the results in the context of your symptoms and other tests.
