Use FedEx Priority Overnight® service for timely delivery
We recommend using FedEx Priority Overnight® service to be delivered by 11:30 a.m. Monday-Friday.
We generally do not recommend using FedEx First Overnight® service, as this tends to be more expensive than and arrive at the same time as Priority Overnight shipments. All other FedEx services – Standard Overnight®, Express Saver®, FedEx 2Day® – will not be delivered to our facility until late afternoon, which will result in a one-day delay and longer turnaround times if daily testing deadlines are missed.
Please use the Test Information and Price List to find submission deadlines for required testing and choose the service that best suits your needs.

Drop off a sample in person
For animals or samples are delivered in person, the Fort Collins laboratory is open Monday-Friday and Saturday mornings. Please note our holiday schedule for intended closures.
After-hours drop off
An after-hours refrigerator for small submissions is located in the sample submission drop-off area at the Diagnostic Medicine Center.
If you have a drop-off submission for clinical pathology during a time the sample receiving area is closed and before midnight (or 3 p.m. on CSU holidays), please call (970) 297-1290 upon drop-off. Failure to contact or leave a message will result in the specimens sitting unprocessed until the sample receiving area reopens the following business day.
Whole animals delivered after hours (5 p.m.-8 a.m. or on weekends and holidays) for necropsy must be submitted through Small Animal Emergency and Urgent Care at the Veterinary Teaching Hospital. Emergency personnel will provide our submission form. All fields must be completed, a detailed history provided, special instructions noted, and the form must be signed/dated. Charges apply to all services and payment will be collected the following business day. Be sure to let hospital staff know the submission is intended for the Veterinary Diagnostic Laboratory. A pathologist will conduct a necropsy the following business day.
Recommendations for timely delivery
Choose a carrier and service (we recommend FedEx or UPS) that will deliver your specimens to meet testing deadlines and provides package tracking. Try to avoid weekend and holiday delivery, because the Veterinary Diagnostic Laboratories have limited hours during these times.
Sample receiving is available Monday-Friday 8 a.m.-5 p.m. with limited hours on Saturdays. Samples received via FedEx or UPS Saturday delivery will be accessioned and refrigerated as necessary until Monday.
We provide fixative-filled containers with pre-labeled USPS mailers/FedEx shipping supplies for your convenience. Simply order your mailers and once received, place a properly packaged biopsy sample in the mailer. Include completed paperwork and pre-filled label, and if shipping with USPS, place the mailer in your mailbox. If shipping via FedEx, use the provided pre-filled FedEx air-bill. We will bill shipping charges on your testing invoice.
Transporting infectious substances
The U.S. Department of Transportation has strict guidelines for transporting infectious substances to protect public health. There are also carrier rule variations. Please familiarize your staff regarding the proper packing of specimens in order to abide by regulations and to protect the safety of those handling and transporting samples.

Specimens submitted to the CSU Veterinary Diagnostic Laboratories, including carcasses, tissues and agents isolated from samples, become the property of the CSU Veterinary Diagnostic Laboratories unless other arrangements are made in writing prior to or at the time of submission.
