Collection Information

GENERAL - Label all containers with appropriate information - Animal ID, Owner Name, Veterinarian, Sample Type, Date.
REFRIGERATION - Refrigerate all samples until shipment.
SERUM - Collect blood in a red top or tiger top blood tube. Allow the sample to clot at room temperature before centrifuging or refrigerating. Serum may be submitted in a spun-down tiger top or poured off after spinning into a secondary tube. If submitting specimens from multiple animals, 1) label each tube sequentially (e.g., 1, 2, 3…) to correspond to the specimen/animal order on the submission form; 2) for each specimen, list animal IDs on the submission form; and, 3) if >10 animals per submission, please submit an electronic spreadsheet with animal IDs (in sequential order) – this will facilitate accessioning and data entry, reducing turn-around time.
FEED/FORAGE - Collect one pound of feed or forage that represents the sample lot needing to be tested in a sealable, plastic bag. Label the bag with appropriate identifying information (owner, type, location, date).

Shipping Information

If shipping different samples/tissue types, clearly label each container with the owner and animal ID (if applicable) and sample/tissue type. Ship specimens overnight with an ice pack. DO NOT SHIP OVER WEEKENDS OR HOLIDAYS.
