Code Test Description * Indicates send out test   T505 Thyroglobulin Autoantibody (Canine)   Specimen 1 ml serum   Method ELISA   Schedule 1–4 working days   Indication Test for Autoimmune Thyroiditis.   Interpretive   Guidelines Thyroglobulin autoantibodies serve as a marker for autoimmune thyroiditis and can precede development of hypothyroidism by 2 to 3 years. False positive Thyroglobulin autoantibody tests have been reported to occur in dogs within 40 days of vaccination.   Comments Detection of Thyroglobulin autoantibodies is much more sensitive than detection of T3 autoantibodies or T4 autoantibodies in dogs with autoimmune thyroiditis. do not use SST.   T721 Tosoplasma Antibody Titer (IgG and IgM)   Specimen 1 ml serum   Method ELISA   Schedule 1–3 working days   Indication Testing for toxoplasmosis.   * S18708 Toxoplasma PCR   Specimen 1 ml whole blood or fluid in LT or fresh tissue in RT   Method PCR   Schedule 5–7 working days   Indication Testing for toxoplasmosis.   Interpretive   Guidelines Most cats will have circulating Toxoplasma gondii DNA within 3 weeks after infection. Organisms may be released from tissue cysts resulting in intermittent positive tesys for months to years in some cats. The presence of circulating organisms has not been found to correlate with clinical disease. Detection of organisms in CSF or aqueous humor may be more significant than detection in blood.   Comments Please send on ice packs.   T205 Triglycerides   Specimen 1 ml serum   Method Colorimetric   Schedule Daily   Indication pEvaluation of hyperlipidemia.   T230 Trypsin-Like Immunoreactivity (TLI)(Canine)   Specimen 1 ml serum   Method RIA   Schedule 2–4 working days   Indication To detect exocrine pancreatic insufficiency, possibly pancreatitis.   Comments 12 hour fast is required.   * S16800 Trypsin-Like Immunoreactivity (TLI)(Feline)   Specimen 1 ml serum   Method RIA   Schedule 5–7 working days   Indication To detect exocrine pancreatic insufficiency, possibly pancreatitis.   Comments 12 hour fast is required. Test is not valid on exotic cats.   T510 TSH   Specimen 1 ml serum   Method IRMA   Schedule 1–2 working days   Indication Evaluation of thyroid status. Monitoring response to thyroid replacement therapy.   Interpretive   Guidelines An elevated TSH concentration is consistent with primary hypothyroidism. Approximately 25–35% of hypothyroid dogs, however, will have a normal TSH concentration. If initally elevated, return of TSH concentrations to the reference range with treatment indicates adequate thyroid supplementation.
