The MSU VDL is closed on limited holidays due to lack of U.S. Mail and commercial delivery service (UPS, FedEx, DHL). To avoid delay of your testing requests, please keep this in mind when shipping specimens. For advice on shipping time- or temperature-sensitive samples around these holidays, please contact the laboratory.

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