Background: In this study the efficiency and sensitivity of stool wet mount and Kato-Katz smear techniques for the diagnosis of intestinal helminthes were compared in order to detect the human intestinal helminths.

Objective: To assess the Sensitivity and Specificity between stool wet mount and Kato-Katz Techniques

Methodology: A total of 200 stool specimens were collected from school children aged 6 to 16 from four primary schools randomly selected in Badessa woreda, West Hararghe Zone, Eastern Ethiopia. Each specimen was smeared on one slide for every technique with a normal saline for wet mount and a cellophane cover for Kato-Katz technique. The overall prevalence of the parasites in each school of the Woreda was determined.

Result: The overall sensitivity of both techniques was calculated. Finally the evaluation of Sensitivity and Specificity of both techniques was interpreted as Kato-Katz technique is more effective and sensitive than stool wet mount technique.

Conclusion: To detect the intestinal helminths especially from carriers and non-symptomatic patients Kato-Katz technique is the selective and sensitive method.
