*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.

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.
Post-mortem examination and dissection of a whole animal to harvest tissues and determine a cause of death. Legal or insurance necropsies will incur additional processing fees.
Avian species such as love birds, cockatiels, etc. are included in this test. For poultry species (chickens, ducks, turkeys, quail, geese, guinea, etc.), please request “Necropsy-Poultry”.
Referral tests are not performed at TVMDL; a processing and shipping fee will apply.
Identification of fungal organisms by PCR and sequencing. This PCR is recommended to complement identification of fungal organisms on histopathology and cytology. The assay is not recommended when fungal organisms are not observed histologically, due to the potential of amplification of non specific contaminants.
Specimen
Paraffin block or curls, 1 H&E slide, and 1 GMS/PAS stained slide.
