Code Test Description * Indicates send out test   * S16580 Panleukopenia Titer IgG and IgM (Feline only)   Specimen 1 ml serum   Method IFA   Schedule 1–3 working days   Indication Determine recent infection or vaccination.   Interpretive   Guidelines A serum IgG titer of 1:10 or greater is consistent with natural exposure, maternal antibody or vaccination. A four-fold rise in IgG titer over 2–3 weeks is consistent with recent exposure or recent vaccination. A serum IgM titer of 1:10 or greater is consistent with recent exposure or recent vaccination.   * S16053 Panleukopenia Vaccine Titer (Feline only)   Specimen 1 ml serum   Method IFA   Schedule 1–4 working days   Indication Tests for immunologic response to vaccine. This test does not assure protection against infection.   Interpretive   Guidelines A result of 1:5 or greater indicates immunologic response to vaccination.   T825 Parasite Identification   Specimen Parasite in alcohol or formalin.   Method Direct examination   Schedule 7 working days   Comments Cover specimen with cover slip and seal with clear nail polish.   * S16595 Parathyroid Hormone (PTH) with Ionized Calcium   Specimen 2 samples preferred PTH: 1 ml serum (frozen) Ionized Calcium: 1 ml serum that has been anaerobically transferred from the spun RT (use a needle and syringe to avoid air exposure) into a plain RT. Label the sample tube as "SERUM" and keep cold.   Method PTH by RIA Ionized Calcium by ISE   Schedule 5–7 working days   Indication Evaluation of patients with hypercalcemia or hypocalcemia. Evaluation of patients with renal failure for renal secondary hyperparathyroidism.   Interpretive   Guidelines Differentials for an elevated ionized calcium and suppressed PTH concentration include hypercalcemia of malignancy, vitamin D toxicity, Addison's disease and granulomatous inflammatory disease. An elevated ionized calcium and mid to high-normal or elevated PTH concentration is consistent with primary hyperparathyroidism. A normal or decreased ionized calcium and elevated PTH concentration is consistent with renal or nutritional secondary hyperparathyroidism. A decreased ionized calcium and low or low-normal PTH concentration is consistent with primary hypoparathyroidism.   Comments Sample for PTH should be frozen and sent on ice packs. Samples for ionized calcium that have been exposed to air may have artifically decreased (Ca2+) and those transported in SST tubes may have artifically increased (Ca2+).
