Discuss your test results with your doctor. This page is for informational purposes only and does not provide a diagnosis.

⚡ Key Facts

• Measures the average volume of platelets in femtoliters (fL) • Approximate range: 7–12 fL • Reflects platelet production dynamics in the bone marrow • No internationally standardized threshold exists

🧪 What Does This Test Measure?

MPV (mean platelet volume) measures the average size of platelets in femtoliters, reflecting bone marrow platelet production dynamics.

📋 Why Is It Ordered?

Ordered for thrombocytopenia differential diagnosis, platelet production dynamics assessment, and as a supplementary inflammatory or cardiovascular marker.

🔧 Preparation

Part of the CBC. No special preparation is required. EDTA storage time significantly affects MPV — analysis should ideally occur within 2 hours.

📊 Reference Ranges

Approximate range: 7–12 fL ⚠️ No internationally standardized threshold exists. Values vary significantly by analyzer and EDTA storage time.

⬆️ High Values

Elevated MPV may be associated with immune thrombocytopenia, diabetes, cardiovascular disease, or compensatory platelet production.

⬇️ Low Values

Low MPV may be associated with bone marrow suppression, aplastic anemia, post-chemotherapy, or hypersplenism.

⚙️ What Can Affect Results?

EDTA storage time, analyzer type, anticoagulant selection, and blood collection technique may significantly affect MPV results.

✅ Key Takeaways

💡

What you learned: MPV reflects platelet production dynamics. It helps distinguish between causes of thrombocytopenia but has no universally standardized reference range.

⛔

MPV alone cannot diagnose platelet disorders. Platelet count, clinical context, and sometimes bone marrow evaluation are needed.
