Multiple Time-Point Aldosterone Test
5 days
Chemiluminescent Immunoassay (CLIA)
Accredited NRL Laboratory
Wednesday and Friday
Eight serial measurements of aldosterone – an exhaustive evaluation. Such a test might capture aldosterone every few hours over 24 hours or under a variety of stimuli/inhibitors. A consistently elevated aldosterone across all eight points would strongly indicate autonomous secretion (as seen in primary hyperaldosteronism), whereas normal subjects would show variation and appropriate suppression at times.
