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

During limited hours on University holidays (11/28, 12/26, 12/29, 12/30, 12/31, 1/2), building access and Client Service telephone lines will be available, and our Receiving/Order Entry staff will be working to ensure your incoming specimens are handled promptly and efficiently. Technical staff will be working to ensure minimal impact on test schedules and turnaround times.

Thank you for choosing the MSU VDL for your veterinary diagnostic needs. We wish you safe and happy holidays!

Please note that the holiday operations schedule for the Clinical Pathology section, located at the Veterinary Medical Center (VMC), supports the VMC’s Emergency and Critical Care services and is different from the holiday operations schedule of the main Laboratory.
