What does the Platelet Count and Mean Platelet Volume test measure?

Why is Platelet Count and Mean Platelet Volume measured?

Platelet count assessment identifies thrombocytopenia — platelet count below 150 ×10³/µL — which may indicate immune thrombocytopenic purpura (ITP), drug-induced thrombocytopenia, bone marrow suppression, splenic sequestration, or consumptive coagulopathy (DIC, TTP, HUS) — and thrombocytosis — above 400 ×10³/µL — which may reflect reactive thrombocytosis from iron deficiency, inflammation, or post-splenectomy state, or essential thrombocythaemia. MPV carries emerging cardiovascular significance — elevated MPV has been associated with increased platelet reactivity, platelet aggregation, and higher risk of arterial thrombotic events including myocardial infarction and stroke, making it a relevant biomarker within Boston Heart Diagnostics' cardiovascular risk assessment context.

Reference ranges

Standard reference

Platelets: 150–400 ×10³/µL; MPV: 7.5–12.5 fL # REVIEWER FLAG: Confirm Boston Heart Diagnostics reference ranges for platelet count and MPV — MPV ranges vary between haematology analyser platforms and are not universally standardised. Confirm whether MPV is reported as a standard component of Boston Heart's CBC.

Functional medicine optimal

Platelets: 180–350 ×10³/µL (functional medicine cardiovascular optimal — very high platelet counts within reference range may be associated with increased thrombotic risk in patients with additional cardiovascular risk factors); MPV: 8.0–11.0 fL. # REVIEWER FLAG: MPV cardiovascular risk optimal range is based on emerging literature and is not a standardised clinical guideline target — reviewer to confirm appropriate framing.

Units

Platelets: ×10³/µL, MPV: fL

Reference ranges vary by laboratory and assay platform. Interpret in context of the issuing laboratory's stated range.
