Measurement of trace minerals by inductively-coupled plasma/mass spectrometry. Targets include copper, cobalt, iron, manganese, molybdenum, selenium, and zinc. A tissue/feed prep fee will be added to tissue and feed specimens.
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 7 days. Tissue and feed samples are tested on Mondays and Thursdays with a turnaround time of 10 days.
Gross examination, specific gravity, biochemical analysis with confirmatory testing, and microscopic analysis of urine sample to complete a full urinalysis.
Measurement of urine cortisol by chemiluminescent assay and urine creatinine by colorimetric assay to determine urine cortisol creatinine ratio (UCCR).
