Therefore, for the diagnosis of T. Present to your audience Start remote presentation. Lastly, the Faust technique showed the highest accuracy in the detection of Toxoplasma gondii when compared to the gold standard. A correctly performed parasitology stool test enables the identification of the etiological agent responsible for the disease, the parasite burden, effective treatment and follow-up.

The Sheather technique showed the highest accuracy in the detection of Ancylostomatidae, while the Sheather and HPLJ techniques showed similar accuracies in the detection of Cystoisospora spp.
Intestinal parasites are considered a serious public health problem due to its high prevalence in poor countries. In the Bland-Altman chart Fig. A critical study of clinical laboratory technics for the diagnosis of protozoan cysts and helminth eggs in feces.
Send link to edit together this prezi using Prezi Meeting learn more: Statistical analyzis were performed using the McNemmar adjustment test 18 which the paired data were evaluated and organized regarding the concordance.
The difference between the number of cysts observed by analyst states shows that detection can change among laboratory workers, even using the same samples.

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.
A simple levitation method for the detection of hookworm ova. Hanstter Hallison Alves Rezende. In conclusion, this study demonstrated that the combined use of parasitological techniques is important for the diagnosis of intestinal parasites in cats. Send the link below via email or IM Copy. Services on Demand Journal.
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.
