Deoxycorticosterone (DOC)
Use
The Deoxycorticosterone (DOC) test measures the level of DOC in the blood. DOC is a steroid hormone that is a precursor to aldosterone and plays a role in the body's water balance and blood pressure regulation. This test is used to evaluate conditions related to adrenal gland function, such as congenital adrenal hyperplasia, aldosteronism, and other disorders that may alter adrenal steroid production.
Special Instructions
Not provided.
Limitations
The test may have limitations in detecting very low levels of DOC, and external conditions or patient medications may influence results. Not all causes of altered DOC levels are due to adrenal disorders. The test might not differentiate between DOC and other similar steroid hormones without confirmation. Analytical interference can occur from substances that share chemical characteristics with DOC.
