Detection of malignant catarrhal fever (MCF) by real-time PCR. This test can distinguish between the ovine, ibex, white tail deer, caprine and alcelaphine herpesvirus-1 strains of MCF.
Specimen
1 g fresh tissue (lymph node, liver, spleen, kidney, lung) and/or 1-2 mL EDTA whole blood.
Measurement of manganese 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:
0.50 mL EDTA whole blood or heparinized blood
5 g fresh liver
50 mg fresh liver biopsy (at least 3 Tru-Cut samples, no fluid added)
500 g feed
5 mL water
For birds, 0.30 mL EDTA whole blood is adequate.
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.
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.
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
50 mg fresh liver biopsy (at least 3 Tru-Cut samples, no fluid added)
500 g feed
For birds, 0.3 mL serum or plasma is adequate.
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.
Post-mortem examination and dissection of a whole fetus or egg to harvest tissues and determine a cause of death. Legal or insurance necropsies will incur additional processing fees.
