Evaluation performance of diagnostic methods of intestinal parasites in school age children in Alkalkla east

Abstract

Although the sensitivity of wet mount technique is questionable, it is the mostly used diagnostic technique for routine diagnosis of intestinal parasites in Sudan. Therefore, the aim of this study was the evaluate performance of diagnostic methods of intestinal eparasits in school age children in Sudan. A cross sectional study was conducted from September to December 2018. Single stool sample was processed for wet mount ,direct formal ether concentration (FEC) and Kato Katz methods. The sensitivity and specifity of diagnostic tests were calculated in terms of the “Gold” standard method( FEC). A total of 100 school age children were participated in this study. The prevalence of intestinal parasites was high (70%) with FEC technique. The sensitivity of wet mount 95.7% , and specifity was 90.9% ,and Kato Katz sensitivity was 74.3% , and specifity was 62.5% against the Gold standard test FEC . Moreover, detect of E. Histolytica was 24 wet mount 28 FEC ,and 0 Kato Katz , Glambia was 29 wet mount , 31 FEC,and 31/kato katz, H.nana was 7 wet mount ,l0 FEC and 10 Kato Katz . Hence, it is preferable to use FEC technique to complement the wet mountt est.
