Test includes analysis of proliferation activity (Ki-67 IHC) and interpretation for melanoma prognosis.
Specimen
One of the following: fixed tissue, paraffin embedded tissue, or 10 unstained formalin-fixed tissue sections on positively charged slides. Slide preparation at TVMDL using submitted tissue will incur a $14.50 charge.
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 $11.25 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)
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.
Referral tests are not performed at TVMDL; a processing and shipping fee will apply.

Measurement of molybdenum by inductively-coupled plasma/mass spectrometry. A $11.25 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
