Performance horse purchase exams should be carefully orchestrated, well executed, and repeatable. The exam and reporting process should consider the business transaction between the veterinarian and buyer, the expectations of the buyer, and the physical characteristics of the horse, with special consideration given to certain physical findings based on its intended use.

The purchase exam may include a variety of laboratory tests as well as imaging techniques such as endoscopy, radiography and ultrasonography. More advanced imaging such as thermography, scintigraphy and MRI may be appropriate in some cases. The appropriate tests and imaging depend on the information gathered during the physical exam and the horse’s intended discipline.

Examine the available literature on the pre-purchase exam around the world and look at a non-published survey of 700 pre-purchase exams in a single practice that shows outcomes and summarizes why some horses were considered unsuitable.

Discover the features of a thorough physical exam (resting and exercising), pertinent historical questions to evaluate the cardio-pulmonary system, and portions of the exam that should be tailored to the horse’s intended purpose. 

Findings that are unlikely to be a problem, as well as those that warrant more in-depth, specialized tests will be discussed, with particular emphasis on the echocardiogram and electrocardiogram (resting and exercising). 

Common potential results and the likely impact on athletic potential will be mentioned.

Explore a systematic approach to the ophthalmic exam focused on identification of ophthalmic abnormalities and anomalies and distinguishing these from variations of normal. Potential clinical significance of ophthalmic findings will be discussed.

Case studies will show how to separate lameness from neurologic conditions, with additional discussion on repeatability of both the lameness and neurologic exams and how these can be made more consistent.

Achieve optimum radiographs through proper positioning and equipment; and review radiographic abnormalities that have little effect on the horse’s future capability.

The spine has become more significant in radiographic pre-purchase exams in the last 10 years. Learn to attain suitable back images with large machines and field portable units.

The use of multiple imaging modalities may clarify issues that are difficult to interpret and provide the client with practical advice. Radiography has been the gold standard, but ultrasound, thermography, nuclear scintigraphy, MRI and even CT may enhance the veterinarian’s ability to dispense good advice to the client. Some newer technology may even provide predictive capabilities.
