Table 3

Contingency table assessing accuracy of LAMP in relation to Kato-Katz technique.

	Kato-Katz (gold standard)		Total
	Positive	Negative
LAMP
Positive	26	5	31
Negative	1	8	9
Total	27	13	40

Sensitivity = 26/27 × 100% = 96.3%.
Specificity = 8/13 × 100% = 61.5%.
Positive predictive value = 26/31 × 100% = 83.9%.
Negative predictive value = 8/9 × 100% = 88.9%.
