The accuracy of the techniques was analyzed based on the parasites that showed the highest frequency, i. The results observed in the McNemar statistical calculations showed a better application of the Faust technique when repeated the same samples by the HPJ technique. Numerous clinical and veterinary diagnostic laboratories seek a parasitological methodology that combines specificity, sensitivity, speed and low operational cost.

The results of this research show that there is a large difference in diagnostic sensitivity by both the technique and the analyzer The results of this research show that there is a great difference in the diagnostic sensitivity both by the technique and by the analyzer.

These four techniques were applied separately to analyze fecal samples, and their accuracy was analyzed based on an evaluation of their sensitivity, specificity, positive and negative predictive values, and Kappa index, resulting in the selection of the Willis technique as the nominal gold standard. Rev Cubana Med Tecnic.

This study underscores the importance of combining parasitological techniques in the diagnosis of intestinal parasites in cats.

Houston, we have a problem! To evaluate the diagnostic tests, the sensitivity, specificity, positive predictive value PPVnegative predictive value NPVand Kappa index K of each technique were compared with the gold standard Willis technique.

Parasitic zoonoses in perspective. Research Note Evaluation of the accuracy of parasitological techniques for the diagnosis of intestinal parasites in cats. This study confirmed that using a combination of the gold standard technique Willis and the HPJL method, which is the technique most widely employed in diagnostic laboratories, increases the diagnostic efficiency. Int J Parasitol ; 30 Several diagnostic techniques have been used in order to identify the different parasite stages, thus providing a more reliable diagnosis.
