A comparative study, of the parasitological techniques: Kato-Katz and coprotest (R)

Parasitological diagnosis should be appropriately conducted with high sensitivity and specificity so that intestinal parasite can be detected as the specific treatment depends on this result. A comparative study was developed to evaluate the concordance between the Kato-Katz and coprotest (R) methods in the detection of helminthes in 332 individuals in Pedro de Toledo. A significant difference was found in the case of the Trichuris trichiura - 16.2 % with the Kato-Katz method and 7.5 % with the coprotest (R) method. Therefore, the positive and negative samples of the coprotest (R) method were compared with the number of eggs per gram of feces (epg) obtained by the Kato-Katz method. When the coprotest (R) method was negative, 65 epg of Trichuris trichiura were found by the Kato-Katz method and when the coprotest (R) was positive the epg according to the Kato-Katz were far higher, 199 epg, which demonstrated that the coprotest (R) was inferior to the Kato-Katz method regarding low intensity infections.38217818
