Cortisol Serial 2 DEX
Code
CDEX2
Results
1-2 Days
Country
CA
Container
2 serum in red top or serum separators
Component
2 Cortisol Assays
Specimen
0.5 mL pre and post labelled serum
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 (mnemonic CDEX3), 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.

CDEX4
Results

Country
CA
Container
4 serum in red top or serum separators
Component
4 Cortisol Assays
Specimen
0.5 mL pre, and 3 post labelled serum
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.
Cortisol, Post
Code
CT448
Results
1-2 Days
Country
CA
Container
Serum in red top or serum separator
Specimen
0.5 mL serum
Description
A single cortisol level, submitted as a post, used to complete an ACTH stimulation or dexamethasone suppression test (8 hours). Exogenously administered corticosteroids (prednisone, prednisolone, methylprednisolone) will be measured by the cortisol assay and should be withdrawn for a period of time dependent upon dose and duration of use prior to testing. Dexamethasone will not be measured by this assay but could affect testing results given its effects on the hypothalamic-pituitary axis. This test is not species-specific.
