Dedicated to providing the most accurate diagnosis and optimal treatment of muscle disorders in horses
Due to restricted activities with COVID-19, we will be suspending diagnostic services beginning March 21 2020. Samples received prior to March 20 will be processed and reports sent out. Please don’t send samples after March 21 until further notice. If samples are submitted by mistake, they will be frozen and stored until lab personnel are again working on campus. The University of Minnesota has also suspended type 1 PSSM genetic testing. Please stay healthy and safe.
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.
