Measurement of metals and minerals by inductively-coupled plasma/mass spectrometry.  Targets include manganese, cobalt, copper, iron, molybdenum, selenium, zinc, arsenic, cadmium, lead, and thallium.

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); or
--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.Turnaround time is 1-3 days for serum/blood samples; 2-5 days for tissue or feed samples.

Follow up test to TVMDL’s Pesticide Screen; Pesticide Quantitation measures pesticides previously identified by Pesticide Screen test. Measurement is performed by gas chromatography/mass spectrometry.

Specimen:

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

Specimen: One or more of the following: 2 cups to 1 quart of GI content, 20 mL water, 500 g feed, 2-4 flakes hay, 10 g bait material.

Detection of desmethylbromethalin, the toxic metabolite of bromethalin, by liquid chromatography/mass spectrometry.

Specimen: One or more of the following: 2-5 g fresh adipose tissue, kidney, brain, liver, bait.
