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.
FRESH TISSUES - Collect tissues in sterile/clean containers (plastic jars or sealable plastic bags). Separate tissues in different containers and label with tissue type, animal ID, and owner name. If submitting serum/plasma, ensure that it is clear (not hemolyzed).
