⚡ Key Facts

• Measures the average volume of red blood cells in femtoliters (fL) • Normal: 80–100 fL • Key parameter for classifying anemia type • Low MCV: microcytic (e.g., iron deficiency) | High MCV: macrocytic (e.g., B12 deficiency)

🧪 What Does This Test Measure?

MCV (mean corpuscular volume) measures the average size of red blood cells in femtoliters, serving as the primary tool for classifying anemia as microcytic, normocytic, or macrocytic.

📋 Why Is It Ordered?

Ordered for anemia classification, investigating the cause of anemia, monitoring treatment response, and nutritional deficiency evaluation.

🔧 Preparation

Part of the CBC. No special preparation is required.

📊 Reference Ranges

Normal: 80–100 fL Microcytic: <80 fL (small red cells) Macrocytic: >100 fL (large red cells) ⚠️ Reference ranges vary by laboratory.

⬆️ High Values

High MCV (macrocytosis) may be associated with B12 deficiency, folate deficiency, alcohol use, certain medications, liver disease, or hypothyroidism.

⬇️ Low Values

Low MCV (microcytosis) may be associated with iron deficiency anemia, thalassemia trait, or chronic disease anemia.

⚙️ What Can Affect Results?

Sample storage time, cold agglutinins, hyperglycemia, reticulocytosis, and certain medications may affect MCV results.

🔬 Evidence Summary

Moderate evidence: 1 guideline, 1 systematic review, and 3 reviews/observational studies.

✅ Key Takeaways

💡

What you learned: MCV classifies red blood cell size and is essential for determining the type and likely cause of anemia.

⛔

MCV alone cannot diagnose the cause of anemia. Iron panel, B12, folate, and clinical context are needed.
