Dedicated to providing the most accurate diagnosis and optimal treatment of muscle disorders in horses
June 15: The Neuromuscular Diagnostic Laboratory has re-opened. Please submit both formalin-fixed and fresh samples. We have a considerable backlog of samples to process from the past 3 months, so please understand that results may be delayed. If there is urgency to your case please indicate this on the submission form and we will do our best to expedite the formalin-fixed stains on your samples. Thank you so much for your patience.
The overarching goal of the equine neuromuscular diagnostic laboratory (NMDL) is to define the basis for neuromuscular disorders in horses, develop accurate, minimally invasive diagnostic tests, and optimal methods for preventing or managing these diseases.
