Clinical Trial: Study on the Diagnostic Cut-off Point of 24-hour Urinary Aldosterone Measured by Liquid Chromatography-Tandem Mass Spectrometry in the Diagnosis of Primary Aldosteronism in the Oral Sodium Loading Test

U.S., June 10 -- ClinicalTrials.gov registry received information related to the study (NCT07635134) titled 'Study on the Diagnostic Cut-off Point of 24-hour Urinary Aldosterone Measured by Liquid Chromatography-Tandem Mass Spectrometry in the Diagnosis of Primary Aldosteronism in the Oral Sodium Loading 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 in measuring aldosterone. This study aims to establish a more precise diagnostic threshold for the oral sodium loading test (OSLT) by using LC-MS/MS to measure urinary aldosterone levels. We will combine the biochemi...
