One or more of the following: 1 mL serum or plasma, 5 g fresh liver, 50 mg fresh liver biopsy (approx. 3 Tru-Cut samples), 500 g feed. For birds, 0.3 mL serum or plasma is adequate.
Do not submit tissues in formalin or saline. For feedstuff, submit a representative sample of the entire ration. Do not centrifuge EDTA whole blood samples. Serum and plasma samples should be centrifuged and removed from the clot.
Tissue or feed: sealed, leak-proof plastic bag or container. A $10 sample preparation fee will be added to tissue and feed specimens.
Serum or plasma: glass or plastic tube with no anticoagulant additives. If zinc toxicity is suspected, use a plastic tube or royal blue top trace mineral tube. If vitamin testing is also desired, wrap tubes in foil or other light-protective material.
Label all samples. Ship overnight on cold packs.
The time required to complete testing of 5 or more feed/tissue samples and 10 or more whole blood samples may take longer than the posted turnaround time. Samples will be processed as quickly as possible.
