Bloody Minded Episode 53 - PlateLOTS | Approaching Thrombocytosis
Jul 15, 2025
Explore the curious case of thrombocytosis, where having too many platelets can cause more problems than they solve. Delve into the biology of platelet production and how misleading lab results can complicate diagnoses. Discover the connection between iron deficiency and elevated platelet counts, alongside the role of cytokines and bone marrow issues.

Episode notes
Iron Deficiency Causes Thrombocytosis
- Iron deficiency reliably causes mild thrombocytosis and is common in the community.
- Microcytic anemia plus thrombocytosis is a strong sign of iron deficiency.
Hyposplenism and Thrombocytosis
- Hyposplenism or absence of spleen commonly causes mild persistent thrombocytosis.
- Platelets avoid sequestration in the spleen, increasing circulating counts.
Drugs Rarely Cause Thrombocytosis
- A few drugs, like clozapine and certain antibiotics, may cause thrombocytosis but this is rare.
- Drug-induced platelet increase is less common than drug-induced thrombocytopenia.
