The MSU VDL is closed on limited holidays when U.S. Mail and commercial delivery services (UPS, FedEx, DHL) are unavailable. To avoid delays in 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.

During limited hours on University holidays (12/24, 12/26, 12/27, 12/30, 12/31), 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. Please note that test schedules throughout the lab may be impacted.

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