The purpose of our study was to establish an assay for the measurement of aldosterone in saliva which utilises a simple, non-invasive sampling technique on an out-patient basis. For this we have developed a non-isotopic, time-resolved fluorescence immunoassay. The assay only requires a volume of 100 μl for each duplicate value obtained and involves an overnight incubation after extraction of samples. Cross-reactivity with potentially interfering steroids is below 0.01%. T...

Background: Screening for primary aldosteronism (PA) using the aldosterone to renin ratio (ARR) is recommended by clinical practice guidelines in patient groups with a high prevalence as the disease is reported by several authors in more than 10% of essential hypertensives (EH).Methods: Plasma aldosterone concentration (PAC) and direct renin (DR) were measured using two novel automated chemiluminescence assays (IDS-iSYS; Boldon, UK) and compared to the S...
