ABSTRACT

Nematode-class intestina lhelminth infection, which is transmitted by soil that has been contaminated with worm eggs is a worm infection Soil-Transmitted Helminths (STH). Worm infection can be detected by checking the stool. Currently, in a clinical publication or epidemiological surveys, the most widely used technique in the diagnosis of parasites is the flotation method. This research will be conducted with the sensitivity and specificity of the flotation method with NaCl and ZnSO4 solutions with the gold standard used, the Kato-Katzmethod. Stool examination conducted aims to see whether the flotation method with ZnSO4 solution is more sensitive for an analysis of STH worm eggs that will be found compared to using a solution of NaCl containing a solution used in the field. The purpose of this study is to examine the sensitivity and specificity of the

NaCl and ZnSO4 solution flotation methods to the examination of Earthworm Transmitted Helminths (STH) and also use the Naot solution flotation efficiency method which is lower than the ZnSO4 solution flotation method.  The sample used is a sample from elementary student collected at the Health Analyst Parasitology Laboratory usingthe NaCl and ZnSO4 solution flotation method. The results of this study indicate the sensitivity of the NaCl solution flotation method of 52.38%, specificity 94.44%, positive predictive value 84.61%, and negative predictive value 77.27% and ZnSO4 solution 71.42%. While the specificity of the flotation method is NaCl solution and ZnSO4 solution is 94.44%. The flotation method of ZnSO4 solution was 71.42%, specificity was 94.44%, positive predictive value was 88.23%, negative predictive value was 85.00%. This research discusses the method of flotation sensitivity ofNaCl solution is lower when compared to the flotation method of ZnSO4 solution.
