Please remember to include the proper submission form(s) with your samples. An accession fee of $8.50 is applied to each accession/case, not each specimen.

As a reminder, turnaround times are estimates in business days and apply to individual tests. Actual reporting of test results depends on the full battery of tests requested, day of the week/time of day samples arrive at the testing laboratory, and the quantity/quality of samples submitted. Research samples may require extended turnaround time. For more information, visit the Testing Information page.

    Trace Mineral Panel (ICP/MS)

    Test Code
    1070
    $40.00

    About this Test

    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. 

    Specimen

    One or more of the following*: 

    • 1 mL serum and/or 0.5 mL EDTA whole blood
    • 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 7 days. Tissue and feed samples are tested on Mondays and Thursdays with a turnaround time of 10 days.

    A tissue/feed prep fee will be added to tissue and feed specimens.
