Cytologic evaluation of body fluid samples. Includes gross examination, total protein concentration, cell counts (where indicated and with EDTA and non-flocculent samples), preparation of direct, concentrated and cytocentrifuge slides (where indicated), and microscopic evaluation by a clinical pathologist.
Measurement of drugs in samples that have been determined to be positive by other TVMDL tests. Measurement performed by liquid chromatography/mass spectrometry (LC/MS).
Specimen
One or more of the following:
5 mL serum
10 mL urine
50 g liver or GI content, medication, livestock feed, pet food
Detection of anabolic steroids by liquid chromatography/mass spectrometry. Targets include boldenone, nandrolone, stanozolol, testosterone, and trenbolone.
Detection of beta-agonist drugs in hair, wool, or feathers by liquid chromatography/mass spectrometry. Targets include clenbuterol, ractopamine, zilpaterol, bambuterol, and albuterol.
Specimen
Equine: Quarter inch diameter of mane (preferred), tail, or body hair with the roots/follicles intact.
Cattle, Sheep, or Goat: Collect enough hair such that the total amount when bunched is approximately 2 cm in diameter. Avian species: 10 broiler feathers or 6 turkey feathers.
Detection of beta-agonist drugs in retina tissue by liquid chromatography/mass spectrometry. Targets include albuterol, clenbuterol, formoterol, metoprolol, ractopamine, terbutaline, and zilpaterol.
Detection of performance enhancing beta-agonist drugs by liquid chromatography / mass spectrometry. Targets include albuterol, clenbuterol, formoterol, metoprolol, ractopamine, terbutaline, and zilpaterol.
Detection of tetrahydrocannabinol (THC), cannabidiol (CBD), their major metabolites, and a variety of synthetic cannabinoids by liquid chromatography/mass spectrometry.
