A normal platelet count ranges from 150,000 to 450,000 platelets per microliter of blood. Having more than 450,000 platelets is a condition called thrombocytosis; having less than 150,000 is known as thrombocytopenia. The medical term for having too many platelets is thrombocytosis, and there are two types: - Primary or essential thrombocytosis – Abnormal cells in the bone marrow cause an increase in platelets, but the reason is unknown - Secondary thrombocytosis – The same condition as primary thrombocytosis, but may be caused by an ongoing condition or disease such as anemia, cancer, inflammation, or infection I would advise you to visit a MD general medicine so that the results can be clinically correlated so that the underlying cause of the problem can be found and treated accordingly.
