A plain-language description with its source has not been added for this biomarker yet. What the laboratories say about the tests that measure it is below.
What the laboratory says this test is for
This panel identifies all major adrenal steroid hormones and facilitates the diagnosis of the four enzymatic defects associated with congenital adrenal hyperplasia (CAH). All steroids are determined in a single assay by LCMSMS using as little as 0.1 mL serum.
Quest Diagnostics test directory, test code 90392
What the laboratory says this test is for
Measurement of corticosterone may help confirm the diagnosis of the very rare aldosterone deficiency disorder, corticosterone methyl oxidase (18-hydroxylase) enzyme deficiency where the ratio of corticosterone to 18-hydroxycosticosterone may be increased.
Quest Diagnostics test directory, test code 6547
What the laboratory says this test is for
All steroids requiring the action of 17-Hydroxylase enzyme are low, including 17-OH Progesterone and Cortisol. Levels of estradiol and aldosterone are also low. Additional testing may be required to establish a diagnosis.
