Code Test Description * Indicates send out test   T125 Cholesterol   Specimen 1 ml serum or heparinized plasma or LT   Method Colorimetric/Enzymatic   Schedule Daily   Indication Evaluation of hyperlipidemia, certain thyroid, liver and kidney disorders.   Interpretive   Guidelines Elevations may be due to diet, nephrotic syndrome, hypothyroidism (dogs), hyperthyroidism (cats) or liver disease. Low levels may be seen with diet, lymphangiectasia, certain liver diseases.   T235 Cholinesterase   Specimen 1 ml serum or heparinized plasma   Method Cobas   Schedule 4&150;6 working days   Indication Diagnosis of organophosphate toxicity.   Interpretive   Guidelines Cholinesterase is irreversably inhibited by organophosphate-containing pesticides, but reversibly inhibited by carbamate insecticides. Low levels support exposure to organophosphate containing substances or carbamates.   16007 Clostridium Perfringens Enterotoxin   Specimen Feces   Method ELISA   Schedule 2–4 working days   Indication Detects C. perfringens enterotoxin as a cause of chronic large bowel diarrhea.   S16195 Cobalamine (Vitamin B12) and Folate   Specimen 1 ml serum   Method Chemilluminescence   Schedule 2–4 working days   Comments Animals should be fasted for 8 to 12 hours.   T535 Coccidioides Titer   Specimen 1 ml serum, joint fluid, CSF or cavitary effusions   Method AGID   Schedule 2–4 working days   Indication Exposure to Coccidioides immitis.   Interpretive   Guidelines IgM titers are usually positive within 1 month of infection and remail positive for approximately 6 months. IgG antibodies do not appear for weeks to months after infection. The IgG titer reflects the severity of the infection and very high titers are usually associated with disseminated disease. Low IgG titers (approx. 1:4) can occur early in the course of infection or with chronic localized disease, or they may persist for months after resolution of active infection.   Comments Identification of organisims is the best way to make a diagnosis, however, organisims are typically difficult to find. The prevalence of coccidioidomycosis in cats is much lower than in dogs.   T540 Coombs' Direct   Specimen 1 LT   Method Agglutination   Schedule 1–2 working days   Indication Investigation of immune-mediated hemolytic anemia (IMHA).   Interpretive   Guidelines A positive test, in conjunction with appropriate clinical signs, is support of IMHA.   * S16210 Copper Level   Specimen 1 ml serum, heparinized plasma or 1 LT   Method Atomic absorption or ICP spectroscopy   Schedule 5–10 working days   Indication To detect exposure to excessive copper levels.   Interpretive   Guidelines For copper storage on block see test S16215 Please send comments to the webmaster. ©1997-2008 Antech Diagnostics, Inc.
