![]() ![]() In FECPAK, a special tube with a central pillar is filled with a stool sample dissolved in flotation solution, allowing the parasite eggs to accumulate into a single viewing area within a fluid meniscus. FECPAK is currently the only method that provides the digitalization of the results of egg counting. This would allow for instant data transfer to the cloud server and to create an archive for reinspection in case of doubt. For real-time monitoring of the prevalence and the intensity of intestinal STH infections during surveillance programs, digitalization of the results is essential. The results of all the methods described above are read by traditional microscopy and are reported as writings on paper. However, omitting the centrifugation step and relying only on the natural flotation of the eggs by Earth’s gravity by shrinking the chamber volumes, resulted in a decrease in sensitivity. One of the main advantages of this new method is the elimination of the centrifugation requirement, allowing easier transfer and simpler application. To overcome this bottleneck, a simplified version of the primary technology has been developed: mini-FLOTAC. The main limitations of the FLOTAC technique are the complexity of the application and the requirement for centrifugation of the sample using a large swinging bucket centrifuge, which is often not available in laboratories in developing countries. ![]() The developers claim that FLOTAC techniques provide the highest sensitivity and accuracy available on the market compared to the methods based on physical separation of the parasite eggs. The system allows analysis of fecal material up to 1 g, compared to 42 mg in KK. The FLOTAC apparatus is a cylindrical device consisting of two 5 mL flotation chambers. FLOTAC technology is based on centrifugal flotation of a fecal sample suspension and subsequent translation of the apical portion of the floating suspension. ![]()
