Flotation Technique for Fecal Parasite Concentration Methods
This technique is predominantly used in parasitology laboratories. By exploiting the density of the parasites, particularly eggs, it allows the parasites to float to the top of a dense solution (final specific gravity of about 1.20) and can then be skimmed from the top of the tube.. The most commonly used reagent is zinc sulphate.Operculated eggs as well as schistosoma and infertile Ascaris

The number of parasitic forms of both protozoan and/or helminthic parasites) in fecal specimens is often too low to be observed microscopically in direct wet mounts or in stained smear preparation.In such cases, the use of concentration techniques increases the chances of detecting parasitic organisms, thus increasing the sensitivity of copromicroscopic techniques.The two most commonly used

The egg opercula pop open due to the high specific gravity of the zinc sulfate, fill with zinc sulfate, and sink to the bottom of the tube. Therefore, using this method, both the surface film and sediment must be examined before reporting the concentration as negative. REFERENCES. Garcia, L.S. 2016.

The FE and the zinc sulfate flotation methods were compared in 2 studies, which found them equally sensitive (Bartlett et al., 1978, Ritchie et al., 1952). The use of ether has since been substituted with ethylacetate, without any change in sensitivity (Erdman, 1981), to become the FEA concentration technique used in this study. Additionally
