Measurement of zinc by inductively-coupled plasma/mass spectrometry. A $10.75 sample preparation fee will be added to tissue and feed specimens.

Specimen:

One or more of the following: 

• 1 mL serum or plasma
• 5 g fresh liver
• 50 mg fresh liver biopsy (at least 3 Tru-Cut samples, no fluid added)
• 500 g feed

For birds, 0.3 mL serum or plasma is adequate.

Blood, serum, and urine samples are tested on Mondays, Wednesdays, and Thursdays with a turnaround time of 5 days. Tissue and feed samples are tested on Mondays and Thursdays with a turnaround time of 7 days.

Measurement of trace minerals by inductively-coupled plasma/mass spectrometry.  Targets include copper, cobalt, iron, manganese, molybdenum, selenium, and zinc.  A $10.75 sample preparation fee will be added to tissue and feed specimens.

Specimen:

One or more of the following*: 

• both 0.5 mL EDTA whole blood and 1 mL serum (both sample types are required)
• 5 g fresh liver
• 50 mg fresh liver biopsy (approx. 3 Tru-Cut samples, no fluid added)
• 500 g feed

For birds, 0.6 mL EDTA or heparinized whole blood is adequate.

*Serum selenium provides current day levels, while whole blood selenium indicates selenium status over a longer period of time. TVMDL can interpret both serum and whole blood selenium concentrations for cattle, horses, sheep, birds or white-tailed deer. For goats, TVMDL has reference values for serum or plasma only.

Blood, serum, and urine samples are tested on Mondays, Wednesdays, and Thursdays with a turnaround time of 5 days. Tissue and feed samples are tested on Mondays and Thursdays with a turnaround time of 7 days.

Follow up test for TVMDL’s toxin screens to provide quantitation for carbamates, cantharidin, ethylene glycol, glycolic acid, or metaldehyde. Measurement is performed by gas chromatography/mass spectrometry.

• 10 g bait (source material)
• 40 g forage or hay
• 20 g liver
• 10 g crop contents
• environmental samples (swabs)

Identification of components and toxic substances, such as plants and plant parts, algae, insects, or bait material.
