ABSTRACT:
A multi-filter apparatus for processing ova and parasites from human and animal specimens. The filtration apparatus includes a specimen receptacle, a filter holder section and a collection receptacle. The filter holder section contains two filters, a coarse filter and a fine filter. The method for using the apparatus includes mixing a specimen with a preservation solution to form a mixture, transferring the solution to the specimen receptacle and then fractionating the mixture. After fractionation, the specimen receptacle, filter holder section and supernatant are conveniently discarded. The resulting concentrated parasite sample may be analyzed using conventional analytic techniques. The invention further includes a kit including a filtration apparatus and a preservation fluid dispenser.
