Thrombocytopenia is common in malaraia and may be multifactorial. Certain platelet parameters may correlate with severity of the malaria.
Patient selection: age > 18 years with malaria
Types of malaria: P. falciparum, P. vivax
Predictors of severe malaria:
(1) platelet count <= 50,000 per microliter
(2) plateletcrit <= 0.05%
