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. A tissue/feed prep 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)
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.
Detection of Mycobacterium avium subspecies paratuberculosis, the causative agent of Johne’s disease, by real time PCR. TVMDL provides an option to pool up to three samples if pooling is indicated on the submission form. Pooling will add an additional $2.50 per sample.
