Hematological parameter	Nonparasitemic (n = 309)	Parasitemic (n = 61)	Sensitivity	Specificity	PPV	NPV	LR	P value
Hb < 10(g/dL)	12	1	16.0	96.1	7	83.1	0.342	0.703
RBC < 4(×10¹²/μL)	39	7	11.5	87.4	17.9	83.3	0.802	1
MCV < 80	77	15	24.6	75.1	16.3	83.4	0.975	177
RDW> 15 (%)	83	17	27.9	73.1	17	83.7	0.872	0.875
PLT < 150 (×10³/μL)	75	26	42.6	75.7	25.7	86.9	0.005	0.005^*

P value < 0.05 was significant at 95% confidence interval.

PPV: positive predictive Value; NPV: negative predictive value; LR: likelihood ratio; CI: confidence interval; RBC: red blood cell; MCV: mean corpuscular volume; RDW: red blood cell distribution width; PLT: platelet count.
