The MSU VDL is closed only on limited holidays when U.S. Mail and commercial delivery services (UPS, FedEx, DHL) are unavailable. Please keep this in mind when shipping specimens to avoid possible delays and contact us for advice on shipping time- or temperature-sensitive samples around holidays.

The Clinical Pathology laboratory, located in the Veterinary Medical Center (VMC), will be open from 9:00 a.m. - 3:00 p.m. to support the VMC's Emergency and Critical Care service.
