Why Test with ParaScreen-e?

Our Mission is Simple:

To provide every horse owner with an easy, convenient and affordable way to obtain equine fecal testing in order to promote responsible and effective deworming programs.

Why is Fecal Testing Important?

Equine intestinal parasites are evolving and developing resistance to the very drugs that have been used to combat them. Without new drugs on the horizon, horse owners need to pay close atten­tion to their deworming practices and develop a more responsible approach to managing equine intestinal parasites.

Today, veterinarians, horse-care professionals and even deworming drug manufacturers recommend pre-treatment fecal testing for iden­tifying and targeting specific intestinal parasites and post-treatment fecal testing to make sure the selected dewormer is working.

Why ParaScreen-e™?

ParaScreen-e is an economical, easy-to-use, mail-in fecal collection kit that provides horse owners with a convenient way of getting labo­ratory fecal testing. Within 24 hours after receipt of your horse’s fecal sample, you will receive the results of a McMaster’s quantitative fecal test performed by New England Horse Labs, a USDA-APHIS certified equine testing facility.

Your horse’s fecal analysis report will identify parasite species and a Fecal Egg Count (FEC) providing you, your veterinarian and/or horse-care professional with the valuable information needed for effective deworming treatment options.

Don’t take chances with your horse’s health using a ‘hit or miss’ ap­proach to deworming. Avoid contributing to the problem of parasite resistance by treating horses unnecessarily. Know what you’re dealing with before deworming.

Develop a more responsible approach to managing equine intestinal parasites by properly fecal testing your horse. Before you Deworm, ParaScreen!


This is the most common type of egg found in the fecal sample.  There are two main types, “large” and “small”.  All Strongyles start out as eggs scattered throughout the environment (feces, soil, etc.) which hatch into larvae that are consumed by horses as they graze or drink infected water. The larvae mature in the intestinal tract.  The “large” Strongyles migrate into either the blood vessels of the intestines or migrate into the liver.  “Small” Strongyles stay within the intestines and burrow (encyst) within the wall of the large intestine. Here they can stay for months or years before the proper conditions trigger them to emerge.  While Strongyles are in this stage, they are not shedding eggs and are not impacted by dewormers but are doing the most damage to the horse.  The “large” Strongyles can cause severe or even fatal colic or blood vessel ruptures as well as weight loss, anemia or colic and the encysted “small” Strongyles can severely damage the walls of the intestines.

Sooner or later, all Strongyles migrate back to the intestines and adhere to the inner walls.  This is when the worms are the least damaging to the horse.  This is when the worms shed their eggs which we find in their feces.
