Unmasking Thrombocytosis: What a High Platelet Count Really Means

Dr. William Aird reminds us on  X that not all elevated platelet counts are alike, and understanding the underlying cause of thrombocytosis is essential for accurate diagnosis and treatment:

“Not all high platelet counts are created equal.
Thrombocytosis can be:
  •  Reactive (infection, iron deficiency)
  •  Clonal (MPNs like ET, PV)
  •  Hereditary (rare mutations)
  •  Spurious (lab artifact)
Knowing the type guides workup and treatment!”

Misinterpreting platelet elevation may lead to unnecessary concern or missed pathology. A tailored diagnostic approach is key.
