Clinical Trial: Study on the Application of Liquid Chromatography-Tandem Mass Spectrometry for the Determination of Aldosterone and Renin Activity in the Diagnosis of Primary Aldosteronism by Captopril Test

U.S., July 10 -- ClinicalTrials.gov registry received information related to the study (NCT07691801) titled 'Study on the Application of Liquid Chromatography-Tandem Mass Spectrometry for the Determination of Aldosterone and Renin Activity in the Diagnosis of Primary Aldosteronism by Captopril Test' on June 03.

Brief Summary: Primary aldosteronism (PA) is the most common cause of secondary hypertension. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) is more accurate than the traditional radioimmunoassay method in measuring aldosterone. This study aims to establish a more precise diagnostic cutoff value for the captopril stimulation test (CCT) by measuring aldosterone levels using LC-MS/MS. The investigators will combine the dete...
