The FST\u00a0is used to confirm PA, but it is an in\u2010patient test due to potentially serious complications such as hypokalemia.

No severe complications were reported in FSTamb patients. No difference was found in the median value for plasma potassium on Day 5 between the two groups. Only three patients (1.9%) in the FSTamb had to repeat the test due to incomplete intake of medications. FSTamb and FSTin were equally accurate. The cost of performing FSTamb was at least 50% lower compared with FSTin ($2400 vs. $5200 per patient). The time needed for FSTamb was 60\u2009min of physician's time and 150\u2009min of nurse's time which were lower than the 5\u2009days in FSTin.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Ambulatory FST is safe and accurate and can be performed with significantly less healthcare costs compared to
