A. lumbricoides infection is one from 17 neglected tropical diseases in Indonesia. But, Infection of A. lumbricoides in Indonesia often undiagnosed. This is because stool examination with Kato-Katz’s method still rarely done. So it needs something alternative examination that more practical and can be routinely carried out. This study was a diagnostic test for blood eosinofil levels in diagnosing A. lumbricoides infection. This research was conducted at a hospital in Medan. This study involved 63 children who had their parents approval. Children stool were examined by Kato-Katz method as a gold standard and blood eosinofil levels was examined as an index in this study. The results showed sensitivity level of eosinofil is 25% and specificity 96,08%, positive predictive value 60%, negative predictive value 84%, positive likelihood ratio 6,38% and negative likelihood ratio 0,78%. The conclusion is elevated blood eosinofil levels cannot be used as an alternative test Kato-Katz in diagnosing Infection of A. lumbricoides.
