  • Mycotoxin (LC/MS) [Referral]

    Mycotoxin screen by liquid chromatography- tandem mass spectrometry (LC/MS/MS). This screen is for corn, grains, silage, forage, hay, DDGs, soybean meal, dry pet food, and TMR. Mycotoxins tested: Aflatoxin B1, B2, G1 and G2, T-2 toxin, Ochratoxin A, and Sterigmatocystin at 20 ppb (0.02 ppm). Fumonisin -B1, -B2, -B3, 15-ADON, 3-ADON, DAS and DON (vomitoxin)…

  • Avermectins (LC/MS)

    Measurement of avermectins, including abamectin, doramectin, eprinomectin, ivermectin, moxidectin and selamectin, by liquid chromatography/mass spectrometry.

  • Bone Marrow Fat [Referral]

    Measurement of the percent bone marrow fat to assess the nutritional status of an individual animal. Recommended for diagnosis of malnutrition / starvation. 

  • Protein – Hay or Forage [Referral]

    Measurement of the total protein content a hay or forage sample.

  • Drug Screen – Unknowns (LC/MS)

    Detection of a variety of drugs in submitted samples. This screen is designed to detect drugs not indicated in other TVMDL Drug Screens. Some of the drugs included in this test are from the following drug classes: Non Steroidal Anti-inflammatory Drugs (NSAIDs) Long-acting Tranquilizers Sedatives Corticosteroids Anabolic Steroids Beta-adrenergic Agonists Local Anesthetics Antihistamines Beta Blockers…

  • Pentobarbital (LC/MS)

    Detection of pentobarbital in submitted samples.

  • Water Analysis – Routine & Metals [Referral]

    Measurement of ions (calcium, magnesium, sodium, potassium), sulfates, chloride, pH, conductivity, and total dissolved salts (TDS), and metals (zinc, iron, copper, manganese) in water.

  • Water Analysis – Routine & Heavy Metals [Referral]

    Measurement of ions (calcium, magnesium, sodium, potassium), sulfates, chloride, pH, conductivity, and total dissolved salts (TDS), as well as metals (zinc, iron, copper, manganese), and heavy metals (arsenic, barium, chromium, cadmium, fluoride, nickel lead) in water. 

  • Water Analysis – Routine [Referral]

    Measurement of ions (calcium, magnesium, sodium, potassium), sulfates, chloride, pH, conductivity, and total dissolved salts (TDS) in water.

  • 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…
