Validation of a New Automated Renin Assay

Abstract
Background: Measurement of plasma renin is important for the treatment of patients with congenital adrenal hyperplasia (CAH) and in the evaluation of patients with suspected hyperaldosteronism. Immunologic assays for plasma renin offer easier implementation and standardization than enzyme-kinetic assays for plasma renin activity, but their sensitivity and specificity have been questioned. We studied a renin immunochemiluminescence assay on an automated platform.
