  • Coronavirus Titer Add-on (Feline)

    Test Code
    ADD08
    Results:
    1-3 days
    Component
    FCV Titer
    Specimen
    0.5 mL serum in red top, white top, or serum separator tube
    Test Description
    This is an add-on test code. This test determines if a cat has antibody titers against Feline Coronavirus (FCV). Titers are determined at 1:400 and 1:1600. A result of less than 1:400 is not the same as a negative titer. A titer of less than 1:400 indicates that the cat does not have high antibody concentrations against FCV.

  • Cortisol

    Test Code
    T445
    Results:
    1-2 days
    Component
    Single cortisol level
    Specimen
    0.5 mL serum in red top, white top, or serum separator tube
    Test Description
    Cortisol Assay, Single Sample

  • Cortisol Serial ACTH 2

    Test Code
    ACTH2
    Results:
    1-2 days
    Component
    Cortisol Assay, 2 Samples: PRE (Baseline) and POST ACTH Stimulation
    Specimen
    PRE: 0.5 mL serum in red top, white top, or serum separator tube for baseline sample (labeled PRE); POST: 0.5 mL serum in red top, white top, or serum separator tube for post sample (labeled POST)
    Test Description
    This is an ACTH stimulation test that requires two samples: one PRE, one POST. Results include baseline cortisol and one POST-ACTH cortisol.

    For trilostane monitoring, ACTH testing should start 4‑6 hours after the morning dose of trilostane. The timing of the test is the same regardless of whether the patient is on SID (morning dose) or BID (morning and evening) and is always 4‑6 hours after medication. Trilostane MUST be administered with food, even on the morning that the ACTH stimulation test is going to be performed. Although we generally recommend an 8‑12 hour fast before blood draw (to avoid gross lipemia and hemolysis) this is NOT recommended when monitoring trilostane therapy.

    The timing of the ACTH stimulation test does not matter in pets being treated with lysodren (aka mitotane).

  • Cortisol Serial ACTH 3

    Test Code
    ACTH3
    Results:
    1-2 days
    Component
    Cortisol Assay, 3 Samples: PRE (Baseline) and 2 POST ACTH Stimulation
    Specimen
    PRE: 0.5 mL serum in red top, white top, or serum separator tube for baseline sample (labeled PRE); each POST: 0.5 mL serum in red top, white top, or serum separator tube for each post sample (labeled POST)
    Test Description
    This is an ACTH stimulation test that requires three samples. One PRE cortrosyn administration and then two POST at established intervals.

  • Cortisol Serial ACTH 4

    Test Code
    ACTH4
    Results:
    1-2 days
    Component
    Cortisol Assay, 4 Samples: PRE (Baseline) and 3 POST ACTH Stimulation
    Specimen
    PRE: 0.5 mL serum in red top, white top, or serum separator tube for baseline sample (labeled PRE); each POST: 0.5 mL serum in red top, white top, or serum separator tube for each post sample (labeled POST)
    Test Description
    This is an ACTH stimulation test that requires four samples. One PRE cortrosyn administration and then 3 POST at set intervals.

  • Cortisol Serial DEX 2

    Test Code
    DEX2
    Results:
    1-2 days
    Component
    Cortisol Assay, 2 Samples: PRE (Baseline) and POST Dexamethasone Suppression
    Specimen
    PRE: 0.5 mL serum in red top, white top, or serum separator tube for baseline sample (labeled PRE); each POST: 0.5 mL serum in red top, white top, or serum separator tube for each post sample (labeled POST)
    Test Description
    This test measures cortisol concentrations before and after administration of exogenous dexamethasone (0 hours followed by an 8 hour sample). This is only a two cortisol assay. The low dose dexamethasone suppression test, a three cortisol sample test (DEX3), is preferred for diagnosing hyperadrenocorticism. The high-dose dexamethasone suppression test, a three cortisol sample test, is used to differentiate pituitary-dependent from adrenal tumor hyperadrenocorticism.

  • Cortisol Serial DEX 3

    Test Code
    DEX3
    Results:
    1-2 days
    Component
    Cortisol Assay, 3 Samples: PRE (Baseline) and 2 POST Dexamethasone Suppression
    Specimen
    PRE: 0.5 mL serum in red top, white top, or serum separator tube for baseline sample (labeled PRE); each POST: 0.5 mL serum in red top, white top, or serum separator tube for each post sample (labeled POST)
    Test Description
    This test measures cortisol concentrations before and after administration of exogenous dexamethasone. This suppression test requires three samples; baseline cortisol prior to dexamethasone administration and two cortisol levels post dexamethasone administration (4 and 8 hours). The low-dose dexamethasone suppression test is preferred for diagnosing hyperadrenocorticism. The high-dose dexamethasone suppression test is used to differentiate pituitary-dependent from adrenal tumor hyperadrenocorticism.

  • Cortisol Serial DEX 4

    Test Code
    DEX4
    Results:
    1-2 days
    Component
    Cortisol Assay, 4 Samples: PRE (Baseline) and 3 POST Dexamethasone Suppression

    PRE: 0.5 mL serum in red top, white top, or serum separator tube for baseline sample (labeled PRE); each POST: 0.5 mL serum in red top, white top, or serum separator tube for each post sample (labeled POST)
    Test Description
    This test measures cortisol concentrations before and after administration of exogenous dexamethasone. This suppression test includes four samples; baseline cortisol prior to dexamethasone administration and three additional cortisol samples post dexamethasone administration (last occurring at 8 hours). Samples taken at 2 or 6 hours are interpreted similarly to those obtained at 4 hours.

  • Crystallographic Stone Analysis

    Test Code
    S16735
    Results:
    2-3 days
    Component
    Nidus Composition, Stone Composition, Shell Composition
    Specimen
    Submit dry stone(s) collected in red top tube or in plain, sterile tube or container.
    Note:
    Stone submitted in formalin is not acceptable as formalin can affect the mineral composition.
    Test Description
    Antech’s stone analysis provides quantitative data on the composition of each stone, evaluating both the core (nidus) and outer layers. Reports include dietary recommendations to guide selection of the most appropriate nutritional profile for the patient, based on the stone’s specific mineral makeup. These insights support individualized dietary and lifestyle strategies to help minimize recurrence risk, as stone composition often reflects the patient’s diet and urinary chemistry.
