Thrombocytopenia as a Diagnostic Marker for Malaria in Patients with Acute Febrile Illness

Table 3

Diagnostic values of platelet count to predict malaria in acute febrile patients.

Parameter	Thrombocytopenia (PLT count <150,000 cells/µl)
Sensitivity	79.5%
Specificity	86.3%
Positive predictive value	54.7%
Negative predictive value	95.3%
Area under the curve (AUC) (95% CI)	0.893 (0.847–0.938)

PLT = platelet count; CI = confidence interval.
