Do thrombopoietin levels help distinguish between primary and secondary thrombocytosis?

By William Aird

No, they are not different between the two conditions.

No significant difference in thrombopoietin (TPO) levels was found between the two groups of patients, indicating that serum TPO levels cannot differentiate between primary and reactive thrombocytosis. No significant correlation was found between platelet count and TPO levels in either ET-PV or reactive thrombocytosis. Source.
