Packaging Samples

Shipment of diagnostic materials is subject to government regulations.  If you want to contact one of our labs with questions about proper packaging of samples, visit our Contact Us page for our laboratory phone numbers and email addresses and see our Packing Guidelines page for CAHFS recommendations for proper, safe packaging of specimens for submission.

Delivery Services

Specimen shipments can be delivered in person, U.S. Mail, or by commercial courier services such as these:  **FedEX,  UPS, Golden State, Greyhound, and others.  Click on the service of interest for details which are listed below.  However, due to delivery reductions at the UC Davis Mail Division, the CAHFS-Davis laboratory no longer accepts samples sent via U.S. Priority Mail Service.
