What is Parasight System?

Parasight System is a minute push-button automated fecal egg count (FEC) method with significantly less variability and more accuracy than the traditional McMaster FEC.  For horses, Parasight identifies and counts strongyle and ascarid eggs using fluorescence imaging technology and an automated software algorithm. The Parasight System provides instant results with an image of the eggs and a count of strongyle and ascarid ova in eggs per gram “EPG). For goats and sheep, Parasight detects round worms:  Trichostrongylus, Haemonchus, Ostertagia, Oesophagostomum, ChabertiaCooperia and Nematodirus.  The test provides a total combined round worm count for all such genera except Nematodirus, which is reported as a separate count. Future versions of the system will include the ability to detect and count other parasitic helminth ova, including, Strongyloides and Trichuris. The easy-to-use Parasight App provides a simple user interface for emailing results.  The Parasight System is the only validated fecal egg count system in the industry. 

Are there published studies and peer-reviewed articles on Parasight System? Is Parasight validated?

Yes.  We have numerous publications in this regard, including peer-reviewed papers in Veterinary Parasitology and the International Journal of Veterinary Parasitology.  All are available for review on this site.  We also have additional validation papers either submitted to peer review or in preparation.

How do I get Parasight in my clinic?

We require an annual agreement that commits to the purchase of a minimum number of consumables.  Once the agreement is in place, hardware is provided for you use at no cost.  We do require a security deposit on the hardware in the form of a valid credit card.

Can I setup a demo of Parasight?

We try to provide all the information to help you in your purchase decision both online and through video chat. Most clients choose to order online and setup the system themselves in less than 20 minutes using our “how-to” videos.  However, we understand that sometimes you just need to see it in person.  We will certainly try to accommodate demo requests, but please understand that that we are a small team and cannot always visit your practice in-person.

Will Parasight System be at any upcoming tradeshows?

Yes.  We actively participate in trade events for AAEP, NEAEP, FVMA, AAEVT, KVMA, Mid-America and more.  Please check our event schedule.

Are results sent to my PMS system?

We currently have integrations available for HVMS and Labdaq.  Clinics using those PMS systems can run a fecal with Parasight System and seamlessly update patient records with test results and record charges for billing.  We are currently working on integrating other PMS systems.

Can I send results to myself and my client?

It is up to you.  You have the option to email results directly to your client along with your treatment recommendations, or you may prefer to review them in-house before communicating with your client.

What is the shelf life of reagents?

Regent liquids include a wash, stain and bleach.  The shelf life is 12 months.  In low volume clinics, however, we do recommend that a portion of the reagents be refrigerated to ensure that a stable environment is maintained in order to maximize shelf-life.

How does Parasight System compare to McMaster or other microscope-based technologies?

Parasight System has been optimized for both accuracy and precision.  Its accuracy was caIibrated to produce, on average, the same egg counts as the McMaster test described in the parasitology guidelines issued by the American Association of Equine Practitioners (AAEP).  As a result, veterinarians can continue using the same familiar metrics (such as treatment thresholds) for their parasite control programs.  Since the McMaster test is notoriously imprecise, calibration was achieved by running hundreds of tests on dozens of samples in order to average out these errors.  Since this process involved counting multiple samples multiple times using both Parasight System and McMaster, it also allowed us to statistically evaluate the relative precision of both tests.  

In summary, our testing and validation of Parasight System have shown that even the least-trained analyst is now capable of producing equine fecal egg counts that surpass the results obtained from the McMaster test detailed in the AAEP guidelines when performed by even experienced parasitologists.

What about tapeworms in horses?

Despite numerous attempts to develop a reliable test, diagnosing equine tapeworm infection remains a challenge. General parasite egg counting techniques, such as the McMaster method, are woefully unreliable for detection of tapeworm eggs in feces. Two studies reported the diagnostic sensitivity of the McMaster method to be below 10%, meaning that 90% of infections will go undetected using this method. Thus, standard egg counting methods cannot be used for diagnosing and monitoring for presence of tapeworms. (Source: Tapeworms in Horses, Gluck Equine Research Center, Martin K. Nielsen, DVM, PhD, DAVCM).

Is Parasight System patented?

Yes, it is.

Is Parasight System portable?

The Parasight System is designed for in-clinic use; however, it can be transported and set up at a show event or in a barn setting.  You will need access to electricity and water (bottled or tap), as well as, and WiFi/wireless connection if you intend to email results.
