  • Bile Acids

    Test Code
    T225
    Results:
    1-2 days.
    Specimen
    0.5 mL serum in red top or serum separator tube.
    Test Description
    Single Bile Acid

    Single sample labelled as either PRE or POST bile acids.

    Interferences: Marked hemolysis and lipemia. Ursodeoxycholic acid may be detected by bile acid assay, causing falsely elevated values.

    Note: Ursodeoxycholic acid may be detected by bile acid assay, causing falsely elevated values. 1.0 mL of serum labeled either as fasted (10-12 hours fast) or post prandial (2-hours after feeding a maintenance diet meal).

  • Bile Acids Avian/Exotic

    Test Code
    AE260
    Results:
    1-2 days.
    Specimen
    0.5 mL serum in red top or serum separator tube.
    Test Description
    Single Bile Acids, Avian/Exotic

    Interferences: Marked hemolysis and lipemia. Ursodeoxycholic acid may be detected by bile acid assay, causing falsely elevated values.

  • Bile Acids PRE and POST

    Test Code
    T220
    Results:
    1-2 days.
    Specimen
    0.5 mL serum in red top or serum separator tube (fasted sample labeled PRE), and 0.5 serum in red top or serum separator tube (2-hour post sample labeled POST).
    Test Description
    Fasted bile acids, 2-hour POST feeding bile acids.

    PRE and POST prandial bile acids.

    Interferences: Marked hemolysis and lipemia. Ursodeoxycholic acid may be detected by bile acid assay, causing falsely elevated values.

    Note: Suggested protocol:
    1. Obtain a fasting serum sample (0.5 mL) and label the tube PRE-prandial.
    2. Obtain a second serum sample (0.5 mL) 2-hours after feeding the animal a maintenance diet and label the tube POST-prandial.

  • Bilirubin, Direct

    Test Code
    DBIL
    Results:
    24 hours.
    Specimen
    0.5 mL serum in red top or serum separator tube.
    Test Description
    D. Bilirubin

    Interferences: Marked hemolysis and lipemia. Lipemia can falsely increase results.

  • Bilirubin, Total

    Test Code
    T090
    Results:
    24 hours.
    Specimen
    0.5 mL serum in red top or serum separator tube.

  • Bladder Tumor Analytes

    Test Code
    T520
    Results:
    1-2 days.
    Specimen
    2.0 mL urine in urine transport tube.
    Test Description
    This test may be used as an adjunct in the diagnosis of transitional cell carcinomas (TCC). The test is a reasonably sensitive (~90%) but not a specific test for TCC. Consider CADET™ BRAF (T1025).

    Interferences: False‑positive results may occur in the presence of proteinuria, aciduria, urinary tract infection, and hematuria. An alternative test to consider is the CADET™ BRAF if looking for a non‑invasive diagnostic test with a far higher sensitivity (95%) and specificity (99%).

  • Blastomyces Antibody

    Test Code
    T525
    Results:
    2-3 days.
    Specimen
    0.5 mL serum in red top or serum separator tube.
    Test Description
    To investigate the possibility of blastomycosis as the cause of clinical signs.

    Note: Test is reported as positive or negative. No titer is given.

  • Blastomyces Quantitative Ag Assay

    Test Code
    S86293
    Results:
    5-7 days.
    Specimen
    2.0 mL urine in urine transport tube.
    Test Description
    Blastomyces dermatitidis Ag, EIA

    An antigen test used to diagnose blastomycosis.

  • Blood Cross Match

    Test Code
    T340
    Results:
    1-3 days.
    Specimen
    1.0 mL EDTA whole blood in lavender top tube and 1.0 mL serum in red top tube for patient and each donor. Tubes labeled as patient and donor. Serum in serum separator tube is acceptable but not preferred.
    Test Description
    Includes Donor ID, Major and/or Minor Cross Match

    Screens for pre‑existing antibodies directed against red cell antigens to determine serological compatibility prior to transfusion. If serum, as well as whole blood, is submitted both minor and major cross‑match will be performed. This test is not intended for use in determining pre‑breeding compatibility testing, neonatal isoerythrolysis, or the prevention of neonatal isoerythrolysis.

    Interferences: Marked hemolysis and lipemia.

  • Blood Type, Canine – Full Panel

    Test Code
    S16100
    Results:
    6-9 business days.
    Specimen
    1.0 mL EDTA whole blood in lavender top tube.
    Test Description
    Blood Type: DEA 1, DEA 4, DEA 5, DEA 7.

    This panel is used for RBC typing for identifying blood donors. It evaluates the presence of the blood group antigens; DEA 1.1, 1.2, 1.3, 4, 5, and 7. Antibody screen can be performed at an extra charge if clients submit serum with EDTA whole blood.

  • Blood Type, Canine DEA 1.1 Only

    Test Code
    T315
    Results:
    1-3 days.
    Specimen
    1.0 mL EDTA whole blood in lavender top tube.
    Test Description
    Blood Type – DEA 1.1

    This test determines the appropriateness of canine blood donors prior to transfusion. Dog Erythrocyte Antigen (DEA) 1.1 is the most antigenic blood group in dogs, and canine blood donors are often screened to see if they are positive or negative for this blood group.

    Interferences: Freezing of sample may preclude testing.

    Note: Keep sample refrigerated prior to transport and send with an ice pack.

  • Blood Urea Nitrogen (BUN)

    Test Code
    T100
    Results:
    24 hours.
    Specimen
    0.5 mL serum in red top or serum separator tube.
    Test Description
    Interferences: Marked hemolysis and lipemia.

  • Bone Marrow and CBC

    Test Code
    BONECBC
    Results:
    1-3 days.
    Specimen
    4 to 5 air‑dried bone marrow slides or bone marrow sample, and 1.0 mL EDTA whole blood.
    Test Description
    Bone Marrow Cytology and Complete Blood Count (CBC)

    This test includes a microscopic evaluation of bone marrow. The report includes descriptions of cellularity, assessment of cell lineage, and pathologist comments. The CBC submitted at the time of the bone marrow sampling is utilized in the interpretation of the bone marrow evaluation to allow for a more complete assessment of the hematopoietic system. A detailed history and time course of events will further aid the pathologist in the interpretation of the findings.

    Note: Ensure the appropriate labeling of lavender top tubes (bone marrow and peripheral blood). Provide a detailed history and any relevant clinicopathologic data for the pathologist’s interpretation.

  • Bone Marrow Core Biopsy

    Test Code
    BMBC
    Results:
    3-5 business days.
    Container
    To prevent severe biopsy damage when temperatures are below freezing, we recommend adding 1:10 ratio of isopropyl alcohol (70% or greater) to 10% neutral buffered formalin.
    Specimen
    Bone marrow needle cores should be taken from the proximal humerus with a 11-to-13-gauge Jamshidi needle 3 to 4 inches long. Submit samples in 10% neutral buffered formalin in an approved biopsy container. Always ship formalin containers separately from cytology slides and other samples.
    Test Description
    This test examines bone marrow for patients with hematopoietic abnormalities. Submit biopsies of marrow in formalin. For best results, a CBC should be submitted simultaneously — this gives the clinical pathologist a more complete view of the hematopoietic system and can help pinpoint disease. A detailed history and time course of events will further aid the clinical pathologist in interpreting the findings.

    For patients with suspected osteomyelitis or tumors of bone, submit biopsies in formalin (or complete limbs dampened with saline) and refrigerated using the standard biopsy FBX test code.

  • Bone Marrow Cytology

    Test Code
    BONE
    Results:
    1-3 days.
    Specimen
    4 to 5 air-dried bone marrow slides or bone marrow sample in lavender top tube. Always ship formalin containers separately from cytology slides and other samples.
    Test Description
    This test includes a microscopic evaluation of bone marrow. The report includes description of cellularity, assessment of cell lineage, and pathologist comments.

    Note: For maximal diagnostic utility, a CBC should be submitted at the time of bone marrow sampling. Additionally, submission of a core biopsy along with an aspirate is necessary for a complete bone marrow evaluation. If submitting bone marrow aspirate slides and a core biopsy sample (formalin), ensure that the formalin sample is in a separate Ziplock bag.

  • Bovine Herpes Virus

    Test Code
    S14456
    Results:
    5-7 days.
    Specimen
    1.0 mL serum in red top or serum separator tube (send on ice).

  • Bovine Viral Diarrhea (BVD) ELISA

    Test Code
    S16844
    Results:
    7-10 days.
    Specimen
    1.0 mL of serum from precolostral newborn calves or calves older than three months are suitable for testing. Ear notches from animals of all ages may also be tested.
