Deoxycorticosterone (DOC) serum analysis is a laboratory test used to measure the level of this steroid hormone produced by the adrenal glands. This analysis is important for evaluating adrenal gland function, as elevated or decreased deoxycorticosterone levels may indicate hormonal disorders such as Addison’s disease or adrenal hyperactivity. The test is particularly used when assessing conditions like fluid retention, high blood pressure, or abnormal changes in sodium and potassium levels in the body. The results help physicians make appropriate treatment decisions and determine the need for further testing.
