6 Best Horse Fecal Test Kits for Horse Owners
Explore the top 6 easy fecal test kits for new horse owners. These kits help you monitor internal parasites for targeted deworming and peace of mind.
You walk out to the barn, dewormer paste in hand, and look at your horse. The calendar says it’s time, but is it really? For decades, we dewormed on a strict schedule, but now we know that approach is contributing to dangerous parasite resistance. Mail-in fecal test kits have changed the game, giving us a simple, affordable way to see what’s actually going on inside our horses and treat them only when necessary.

Why Regular Fecal Testing is Key for Horse Health
The single biggest reason to test is to fight parasite resistance. When we use dewormers that aren’t needed, we kill off the weak parasites and leave the strong ones to reproduce, creating "superworms" that are harder to treat. Fecal testing lets us use these valuable medicines strategically, preserving their effectiveness for when they’re truly required.
This isn’t about getting your horse’s parasite count to zero. A healthy horse can and will have a small parasite load. The goal is to identify the "high shedders" in your herd—the 20% of horses that are typically responsible for 80% of the pasture contamination. By testing, you can target these specific animals for treatment, which is better for them and for the health of your entire property.
Ultimately, it’s about making informed decisions instead of guessing. You save money by not buying dewormer you don’t need, and you gain peace of mind knowing you’re doing what’s best for your horse’s individual health. It’s a smarter, more sustainable way to manage your animals.
What to Look For in a Mail-In Fecal Test Kit
Not all kits are the same, and the best one is the one that fits your needs and gives you clear, actionable information. The first thing to consider is what’s included. A great kit for a beginner comes with everything: gloves, a collection bag or container, clear instructions, and a pre-paid mailer. The fewer things you have to figure out yourself, the better.
Next, think about the report you’ll get back. Some labs just send a number—the Fecal Egg Count (FEC). Others provide a more detailed report that explains what the number means, identifies the types of parasites found, and offers general guidance. For your first few tests, a more comprehensive report is incredibly helpful.
Here are the key factors to weigh when choosing a kit:
- Simplicity: Does it make the process easy from collection to mailing?
- Turnaround Time: How quickly will you get results after the lab receives the sample? A few days is typical.
- Report Clarity: Is the information easy to understand for a non-scientist?
- Customer Support: Can you call or email someone with questions?
Horsemen’s Lab Kit: Simple and User-Friendly
If you’re new to fecal testing and want a process that is absolutely straightforward, Horsemen’s Lab is a fantastic starting point. Their kits are designed with the user in mind, eliminating any potential confusion. They are known for being incredibly simple and reliable.
The process is as easy as it gets. You receive a small package with everything you need. The instructions walk you through collecting the sample, sealing it in the provided container, and placing it in the postage-paid mailer. There’s no guesswork involved, which is exactly what you want when you’re starting out.
The results are typically returned quickly via email and are presented in a way that’s easy to digest. They give you the numbers but also help you understand the context. This makes the follow-up conversation with your veterinarian much more productive because you’re coming to them with clear, solid data.
UEN (Para-site.com) Test: Fast, Reliable Results
For the horse owner who wants university-backed accuracy and fast results, the kits from the University of Tennessee’s Equine Nematode (UEN) Surveillance Program are a top choice. This isn’t just a commercial lab; it’s a research institution, so you can be confident in the precision of their analysis. Their service is often found at para-site.com.
The main draw here is the combination of speed and scientific rigor. Once they receive your sample, you often have results in your inbox within 24 to 48 hours. This quick turnaround is invaluable if you suspect a problem or need to make a timely management decision.
While their reports are scientifically sound, they are also designed to be understood by owners. This service is an excellent fit if you have a strong working relationship with your vet. You can forward the detailed report directly to them to formulate a precise, evidence-based deworming plan.
FEC Source Kits for Multi-Horse Households
Managing one horse is one thing; managing a small herd is another. When you have two, three, or more horses, the cost and logistics of individual testing can add up. FEC Source and similar services cater specifically to this scenario by offering bulk kits that are both economical and easy to manage.
These kits provide a significant cost savings per horse, making regular testing for your whole herd much more affordable. They come with multiple collection sets and clear labeling systems, so you can easily keep track of which sample belongs to which horse. This organization is critical for getting an accurate picture of your farm’s overall parasite load.
By testing everyone at once, you can identify your high and low shedders and manage your pastures and deworming schedule accordingly. It transforms your parasite control from a horse-by-horse chore into a comprehensive farm management strategy.
Eggzamin Mail-In Test for Targeted Deworming
The philosophy of modern parasite control is built around targeted deworming, and Eggzamin is a service that leans heavily into this principle. Their entire process is designed to empower horse owners to move away from calendar-based schedules and toward a smarter, test-based approach.
What sets them apart is the educational component. Their reports don’t just give you a number; they help you interpret it within the framework of a targeted deworming program. This context is crucial for understanding why a low-shedding horse might not need dewormer, even when the calendar says it’s "time."
Using a service like Eggzamin helps you become a more knowledgeable partner in your horse’s health. You’re not just collecting data; you’re learning how to use that data to make better decisions. It’s the perfect tool for anyone committed to reducing chemical use and combating parasite resistance on their farm.
Collecting and Submitting Your Horse’s Fecal Sample
The accuracy of your test results depends entirely on the quality of the sample you provide. The most critical rule is to get it fresh. Ideally, you should collect a sample from a manure pile that you physically saw your horse pass. If that’s not possible, choose one that is obviously very recent—still warm or moist.
You don’t need a lot. Grab a pinch from the very top or center of a fecal ball, avoiding any part that has been in contact with dirt, shavings, or old manure. A golf-ball-sized amount is more than enough for the lab to work with. Use the glove and container provided in your kit to keep it clean.
Once collected, seal the sample bag tightly, squeezing out any excess air. Label it immediately with your horse’s name, the date, and any other information the kit requires. Keep the sample refrigerated (but never frozen) until you’re ready to ship it. To ensure it arrives at the lab in good condition, mail it early in the week (Monday or Tuesday) to prevent it from sitting in a post office over the weekend.
Interpreting Results and Creating a Deworming Plan
When you get your results, you’ll see a number listed as EPG, which stands for "Eggs Per Gram." This is the concentration of strongyle-type parasite eggs found in your horse’s manure sample. It’s a snapshot in time, not a permanent diagnosis of your horse’s health.
Most veterinarians use a general classification system to interpret these numbers, though the exact ranges can vary. A common breakdown looks like this:
- Low Shedder: Under 200 EPG. These horses have good natural immunity and are contaminating the pasture very little.
- Moderate Shedder: 200 – 500 EPG. These horses may or may not require treatment, depending on their health and history.
- High Shedder: Over 500 EPG. This horse is a significant source of pasture contamination and will likely benefit from a targeted deworming.
The most important step is discussing these results with your veterinarian. A fecal test result is just one tool. Your vet will combine this information with your horse’s age, health status, time of year, and living situation to create a deworming plan that is right for your specific animal. This partnership is the key to responsible and effective parasite control.
Moving from a rigid deworming schedule to a test-based strategy is one of the most powerful changes you can make for your horse’s long-term health. These easy-to-use mail-in kits remove the barriers, putting crucial information directly into your hands. It’s a simple, affordable, and responsible practice that gives you true peace of mind.
