Code Test Description * Indicates send out test   * S16596 Parathyroid Hormone Related Protein (PTH-rp)   Specimen 1 ml plasma (frozen) from LT in RT or plastic vial   Method RIA   Schedule 7–14 working days   Indication Tests for hypercalcemia of malignancy.   Interpretive   Guidelines An elevated PTH-rp concentration supports a diagnosis of hypercalcemia of malignancy. A normal PTH-rp conentration does not exclude a diagnosis of hypercalcemia of malignancy.   Comments Serum am give false negative results and is not recommended.   T395 Partial Thromboplastin Time (PTT)   Specimen 1 full BT   Method Mechanical   Schedule Daily   Indication Evaluation of bleeding disorders. Evaluates the intrinsic and common coagulation pathways.   Interpretive   Guidelines Prolonged with deficiencies of Factors VII, IX, XI, XII and fibrinogen. Also increased in DIC.   Comments Requires adequate blood: citrate ratio (9:1). BT must be at least half full.   T690 Parvovirus Antibody Titer IgG and IgM (Canine only)   Specimen 1 ml serum   Method IFA   Schedule 1–2 working days   Indication Determine recent exposure to canine parvovirus.   Interpretive   Guidelines An elevated IgG titer is consistent with immune response following vaccination or exposure to natural infection. A four-fold rise in titer over 2–3 weeks is consistent with active infection. An IgM titer of 1:10 or greater is consistent with recent exposure or recent vaccination.   Comments This test is for canines only; see panleukopenia for felines.   T695 Parvovirus Antigen (Canine only)   Specimen 1 g fresh feces   Method ELISA   Schedule 1–2 working days   Indication To determine active parvovirus infection.   Interpretive   Guidelines Virus is shed in the initial phase of the disease. False negative results may occur in the prepatent and recovery phases of the diesase.   Comments Positive fecal test is presumptive evidence of infection. Antigen is measurable for only 24–96 hours after the pnset of clinical signs. Recent vaccination (2 weeks) with modified live vaccine may cause false positive results.   T697 Parvovirus (Panleukopenia) Antigen (Feline only)   Specimen 1 g fresh feces   Method ELISA   Schedule 1–2 working days   Indication To determine active parvovirus infection.   Interpretive   Guidelines Virus is shed in the initial phase of the disease. False negative results may occur in the prepatent and recovery phases of the diesase.   Comments Positive fecal test is presumptive evidence of infection. Antigen is measurable for only 24–96 hours after the pnset of clinical signs. Recent vaccination (2 weeks) with modified live vaccine may cause false positive results.   T700 Parvovirus Antigen and Antibody   Specimen 1 g fresh feces and 1 ml serum   Method Antigen: ELISA Antibody: IFA   Schedule 1–3 working days   Interpretive   Guidelines See individual tests.
