The study aims to compare the effectiveness and sensitivity of three parasitological techniques in the diagnosis of helminthiasis in an endemic area in northeastern Brazil. This is an epidemiological, descriptive and comparative study, carried out in the municipality of Maruim, which is approximately 30 km from the capital of the state of Sergipe, the city of Aracaju. Kits were distributed and 3 samples were collected daily between September 17th and 20th, 2018, later the samples were transported to the Entomology and Tropical Parasitology laboratory of the Federal University of Sergipe to perform macroscopic analysis, applying the Kato-Katz method, Hoffman, Pons and Janer, and the Ritchie method. A higher prevalence of positive cases for Schistosoma mansoni (48.12%), hookworms (4.38%) and Hymenolepis nana (2.50%) was found when analyzed using the Kato-Katz technique, the helminths Enterobius vermicularis (5 .62%), Trichuris trichiura (36.25%) and Strongyloides stercoralis (5.0%) were found to be more frequent when using the Ritchie technique. The techniques proved to be very efficient in identifying the parasites, but not all parasites were identified simultaneously by the techniques. Based on this information, it is concluded that one technique can complement the other in the parasitic diagnosis, thus increasing its sensitivity.
