Paracount-EPG™ Kit — 2 Green Grid Slides

Paracount-EPG™ Kit — 2 Green Grid Slides

This kit includes components to determine a quantitative Egg Per Gram (EPG) count in grazing animals and ruminants utilizing a modified McMaster egg counting technique. The Paracount-EPG™ test is simple and quick. A fecal sample is mixed in volumetric proportion in a calibrated vial with flotation solution. An aliquot is then transferred to our specialized counting slide which is observed microscopically at 100X. Eggs within the slide’s grids are counted, a multiple factor applied, and the EPG determined.

This kit includes (2) Two-Chamber Green-Grid Grid McMaster Counting Slides, (2) Calibrated mixing vials,

(2) transfer syringes, (1) 5-Step Quick Guide, and (1) Kit Booklet with pertinent information and parasite reference images.


    While the Paracount-EPG™ kit is primarily for veterinary and other laboratory technicians, breeders of horses, cattle, sheep, goats and other ruminants may find the kit useful under the guidance of a professional. Chalex, LLC discourages its use unless a professional trained in parasitology is consulted. Additional equipment necessary is a microscope with 10 x 10 for total 100X power and a mechanical stage, and a commercial flotation solution. We discourage the use of non-commercial solutions.

    The kit performs a quick quantitative fecal test for an EPG, also the most accurate indication of parasite paddock or pasture contamination, which in turn leads to reinfection in the animal. An effective parasite control program can be based on quantitative fecal analysis. The primary objective of the control program should be to monitor and maintain EPG counts at low levels and to deworm at targeted egg counts appropriate for the individual animal. By basing anthelmintic applications on EPGs rather than on arbitrary intervals, a more effective program can be established for thriftier animals, and possible economic savings with less chemicals applied to both the animals and their environment.

    • Tests anthelmintic efficacy in specific EPG terms
    • Costs less and takes less time than other techniques
    • Tells when to deworm, based on the EPG you target
    • Quantifies any resistance to an anthelmintic
    • Helps determine the timing of applications in rotational deworming programs which use drugs of varying effectiveness
    • Indicates the degree of environmental contamination occurring
    • Components are reusable
