MPV measures the average size of platelets in the blood. Younger platelets are generally larger than older ones. MPV is used to differentiate between causes of thrombocytopenia (low platelet count). If the platelet count is low but the MPV is high, it suggests the bone marrow is rapidly producing new platelets to compensate for peripheral destruction.

Why Context Matters
Sample handling is a major confounding factor; platelets collected in EDTA tubes swell over time, meaning a delay in lab processing can lead to a falsely elevated MPV measurement. Interpretation must always be paired with the absolute platelet count.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
