The Parasight Fecal Egg Count Test

Parasight Fecal Egg Count Test
Fecal egg counts, including a deworming consult, are available through our Wellness Plans or as an individual service. Dr. Garfinkel incorporates the use of the Parasight system for efficient and accurate results. The Parasight is a 2.5 minute validated fecal egg counter that uses fluorescence-imaging technology and a automated counting algorithm to identify and number specific parasites present. The results are then stored permanently in your horses medical records and can be sent directly to you. Once parasite loads have been determined and evaluated, Dr. Garfinkel will get you set up with an appropriate deworming protocol to treat and then manage your horses condition.

What is different about Parasight?

It has an improved accuracy and precision than the old method of egg counting called the ‘McMaster fecal flotation’. The McMaster test is susceptible to human errors both in test preparation and counting. Parasight uses digital analysis of protein binding to eggs with a proven algorithm.

Why test for worm eggs?

Most horses are exposed to worms throughout their life but high burdens in the gut challenge the horses gut health, immune system and well-being. We want to test and identify these horses so that they can be treated appropriately.

Why not just give a de-wormer?

De-wormers reduce the worm/parasite burden in the gut. Many horse owners are used to giving de-wormers (anthelmentics) multiple times in a year, however some horses do not need the “de-wormers” as often because their worm count is low. Giving de-wormers to these horses contributes to drug resistance. We want to test and identify these horses so they do not get inappropriate treatment.

Why not just alternate the de-wormer I give my horse?

In a horse with low worm burden this also contributes to drug resistance. A big concern is that there are no new de-wormers (anthelmentics) coming to market.

When to test?

Routine testing is done TWICE A YEAR. For horse with higher worm burdens we recommend testing more frequently.
