Weighted results showing the validation of RDT to detect parasitemia using thick-film microscopy by experienced local microscopists, among children 0–15 years surveyed between April 2015 and June 2016 in western Kenya

TFM by experienced local technicians
	Negative weighted % (n)	Positive weighted % (n)	Total weighted % (n)
Rapid diagnostic test
Negative	59.6 (532)	4.0 (39)	63.6 (571)
Positive	18.1 (157)	18.3 (206)	36.4 (363)
Total	77.7 (689)	22.3 (245)	100.0 (N = 934*, N weighted = 1,612,821)

RDT = rapid diagnostic test; TFM = thick film microscopy. The sensitivity of detecting parasitemia by RDT was 82.0% (75.1%, 89.0%) and the specificity was 76.8% (69.4%, 84.1%) as compared with TFM by experienced local technicians.

^*Results do not include 31 children not successfully tested: two missing RDT results, 15 missing TFM results, and 14 missing both.
