-
Avermectins (LC/MS)
Measurement of avermectins, including abamectin, doramectin, eprinomectin, ivermectin, moxidectin and selamectin, by liquid chromatography/mass spectrometry.
-
Pesticide Screen (GC/MS)
Detection and identification of a variety of chemicals including organophosphates, organochlorines, carbamates, industrial pollutants, polycyclic aromatics, aliphatic hydrocarbons, miscellaneous pesticides, some natural products and some drugs using gas chromatography – mass spectrometry (GC/MS). Samples are screened using multiple instrument libraries containing mass spectra for thousands of compounds. Positive identification of a suspect sample is made by comparing sample mass spectra with that of a certified reference standard.
-
Toxin Quantitation (GC/MS)
Follow up test for TVMDL’s toxin screens to provide quantitation for carbamates, cantharidin, ethylene glycol, glycolic acid, or metaldehyde. Measurement is performed by gas chromatography/mass spectrometry.
-
Drug Screen – Cannabinoids (LC/MS)
Detection of tetrahydrocannabinol (THC), cannabidiol (CBD), their major metabolites, and a variety of synthetic cannabinoids by liquid chromatography/mass spectrometry.
-
Glyphosate (GC/MS)
Detection of glyphosate and aminomethylphosphonic acid (AMPA) by gas chromatography – mass spectrometry (GC/MS).
-
Strychnine (LC/MS)
Qualitative detection of strychnine using liquid chromatography – tandem mass spectrometry (LC-MS/MS).
-
Cantharidin (LC/MS)
Detection of cantharidin, the toxic chemical produced by blister beetles, by liquid chromatography/mass spectrometry. A $10.75 sample preparation fee will be added to feed samples.
-
Heavy Metal Panel – Avian (ICP/MS)

-
Heavy Metal Panel – Non-Animal (ICP/MS)
Measurement of heavy metals by inductively-coupled plasma/mass spectrometry. Targets for feed samples include lead, arsenic, cadmium, and thallium. A $10.75 sample preparation fee will be added to feed specimens.
-
Feed Tag Test (Proximate Analysis) [Referral]
Measurement of nutritional components in feed to include moisture, dry matter, crude fat, crude protein, crude fiber, calcium, phosphorus, magnesium, potassium, ash, calculated total digestible nutrients (TDN), net energy for maintenance (NEm), net energy for gain (NEg), and net energy intake (NEl).
