[Efficiency of standard versus instrumental studies in detecting helminth eggs].

Testing confirmed that the applied brush washing methods developed in the 1970s could provide the adequate representativeness of a sample and full information on the actual presence of helminth eggs in the objects under study. An instrumental study was found to increase the probability of helminth egg detection by up to 3.1 times due to the representativeness of a sample, to reduce the labor- and time-consumption to have analysis results, as well as to unify a procedure for sanitary parasitological studies of washouts, and to enhance the efficiency of the equipment already used in parasitology laboratories.
