A prepurchase exam is a very detailed exam that is paid for by a potential buyer. It can be as simple or thorough as the purchaser is willing to do. The horse’s conformation is evaluated and every flaw pointed out even if it’s not one that will be problematic. The doctor will evaluate the horse for the use the purchaser is buying it. Bloodwork and radiographs are also available depending on how detailed an analysis the purchaser is interested in.
