Analytical Testing Analytical testing capabilities for drug testing have evolved significantly over the years. Historically, techniques such as thin layer chromatography (TLC), gas chromatography (GC) and gas chromatography – mass spectrometry (GC/MS) were used to detect drugs. More modern day tests include enzyme-linked immunosorbent assay (ELISA), high-pressure liquid chromatography (HPLC) and liquid chromatography – mass…
Therapeutic drugs can significantly improve the quality of life in animals with painful or long-term illnesses. However, it’s critical to monitor the level of medication in an animal’s body to ensure the dosage is safe and effective. The bodily response to therapeutic drugs is particularly important to monitor in pets with chronic conditions, such as…
Canine Diagnostic Testing Canine Basic Thyroid Panel (T4, TSH, Free T4)The two most frequent thyroid disorders in dogs are primary hypothyroidism and euthyroid sick syndrome (repressed pituitary-thyroid axis due to non-thyroid illness). Additionally, some medications can induce hypothyroxinemia in dogs (i.e. phenobarbital, sulfa drugs, glucocorticoids). Other variables that may affect T4 and TSH include diestrus,…
Panel of tests including T4, TSH, and FT4. Together these results allow further characterization of low T4 from hypothyroidism, drug effects, or euthyroid sick syndrome.
The thyroid gland serves an important function in the overall health of animals. However, it can also lead to a host of health issues if not functioning properly. The Texas A&M Veterinary Medical Diagnostic Laboratory (TVMDL) offers several options for assessing thyroid disorders. In addition to individual tests, TVMDL offers several panels specifically for canine,…
The Analytical Chemistry Section encompasses toxicology and drug testing. In this section, specimens are analyzed to diagnose poisonings and toxins. Specimens analyzed may include animal tissues, ingesta, blood, urine, plants, feed, hay, water, baits, fertilizer, etc. Staff can also identify poisonous plants and nutritional deficiencies of trace metals and vitamins. This section also identify drugs…
The carcass of a female, approximately 112-pound Landrace-Yorkshire pig, was submitted to the Texas A&M Veterinary Medical Diagnostic Laboratory (TVMDL) for necropsy. History noted the pig died suddenly without previous clinical signs. The pig was the only one affected of a group of swine breeding stock destined for research purposes. At necropsy, there was extensive…
