Platelet Count
Platelets (thrombocytes) are small, disc-shaped cell fragments produced in bone marrow. When you get a cut, platelets rush to the site, stick together, and form a plug to stop bleeding. They also release chemicals that activate the clotting cascade. Platelet count is critical for assessing bleeding risk and clotting disorders.

Reference ranges may vary by laboratory. Always compare with the range printed on your lab report.
What Low Levels Mean
Low platelets (thrombocytopenia) increase bleeding risk — you may notice easy bruising, prolonged bleeding from cuts, blood in urine or stool, or petechiae (tiny red dots on skin). Causes include viral infections (dengue), medications, autoimmune conditions (ITP), liver disease, and bone marrow disorders.
What High Levels Mean
High platelets (thrombocytosis) can be reactive (due to infection, inflammation, iron deficiency) or primary (bone marrow disorder). Very high counts increase the risk of abnormal blood clots, which can cause stroke or pulmonary embolism.
Frequently Asked Questions
What platelet count is dangerous?
Below 50,000/µL increases bleeding risk during surgery. Below 20,000/µL can cause spontaneous bleeding and is considered critical. Above 1,000,000/µL (seen in essential thrombocythemia) significantly raises clot risk.
Can dengue fever affect platelets?
Yes, dengue is one of the most common causes of sudden platelet drops in India. The virus suppresses bone marrow and increases platelet destruction. Platelet count is monitored daily during dengue, and transfusion may be needed if it falls below 10,000–20,000/µL.
How can I increase my platelet count naturally?
Foods rich in folate (leafy greens), vitamin B12 (dairy, eggs), vitamin C (amla, citrus), and iron support platelet production. Papaya leaf extract has some evidence of boosting platelets. However, severely low counts need medical treatment, not just diet.
