iron deficiency and thrombocytosis definition
Thrombocytosis is defined as a platelet count greater than 400 Ã 109/L. In routine clinical practice, thrombocytosis is much more likely to be reactive (> 80% of cases) than primary. Reactive thrombocytosis is usually associated with infections, inflammation, trauma, hemolysis, metastatic cancer, the postsplenectomy state, or iron deficiency anemia.
In this review, thrombocytosis will be arbitrarily defined as a platelet count greater than 450,000/microL, a value that has also been chosen by World Health Organization investigators as one of the criteria required for the diagnosis of essential thrombocythemia (table 1).
