The Platelet Count test measures the number of platelets — the tiny, disc-shaped blood cells produced by the bone marrow that are essential for blood clotting and wound healing — circulating in the blood. Too few platelets (thrombocytopenia) causes abnormal bleeding and bruising; too many (thrombocytosis) can increase clot formation risk. Platelet count monitoring is critically important in dengue fever, immune thrombocytopenia (ITP), chemotherapy-induced suppression, and bleeding disorder evaluation. No fasting required.
Key benefits of this package include:
What Does the Platelet Count Test Measure?
| Level / Result | Possible Interpretation |
|---|---|
| 150,000–400,000/µL (Normal) | Normal platelet count — adequate haemostatic function |
| 100,000–150,000/µL (Mild thrombocytopenia) | Mildly low — usually asymptomatic; monitor closely; investigate cause |
| 50,000–100,000/µL (Moderate thrombocytopenia) | Increased bleeding risk with trauma or surgery; investigate cause; avoid invasive procedures |
| 20,000–50,000/µL (Severe thrombocytopenia) | Significant spontaneous bleeding risk; petechiae, purpura, mucosal bleeding likely; medical review required |
| < 20,000/µL (Critical thrombocytopenia) | High risk of spontaneous internal bleeding — urgent medical attention; platelet transfusion may be required |
| 400,000–600,000/µL (Mild thrombocytosis) | Usually reactive — infection, iron deficiency, post-surgery, inflammation; investigate underlying cause |
| > 1,000,000/µL (Extreme thrombocytosis) | Essential thrombocythaemia or primary myeloproliferative disorder — haematology evaluation required |
Important Note: Platelet count must be interpreted alongside the clinical picture — symptoms, bleeding history, medications, and CBC findings. EDTA-induced platelet clumping can cause falsely low automated counts (pseudothrombocytopenia) — confirmed by peripheral smear showing platelet aggregates. A repeat count in a citrate tube will give the true result. All significant platelet abnormalities must be reviewed by a physician.
Platelet Count in Dengue — A Critical Monitoring Tool: Dengue fever causes thrombocytopenia through two mechanisms: direct viral infection of megakaryocytes (reducing platelet production) and immune-mediated platelet destruction. Platelet counts typically begin falling on Day 3–4 of fever, reaching a nadir around Day 5–7 before recovering. A count below 100,000/µL warrants close monitoring; below 20,000/µL — particularly with bleeding signs — often triggers hospitalisation. Daily or twice-daily platelet counts are standard dengue management in India. Medall offers priority dengue panel testing with rapid turnaround.
