11-Deoxycorticosterone is a mineralocorticoid hormone involved in mineral and fluid regulation. An increase or decrease in the level of 11-Deoxycorticosterone significantly affects blood pressure regulation and electrolyte imbalance. Testing its level is indicated in mineralocorticoid disorders, such as primary aldosteronism or congenital adrenal hyperplasia. Testing helps in diagnosing and managing diseases affecting the adrenal, mineralocorticoid function, and renin aldosterone systems.
