About this trial

The goal of this observational study is to see if there is a cyclical or exaggerated diurnal variation in aldosterone production in people with Primary Aldosteronism.

Eligibility criteria

Qualifiers

People with clinically suspected PA but have not met criteria for diagnosis. Suspicion based on low-renin (renin activity <0.5 nmol/h/L or renin mass <5 ng/L), plasma sodium > 140mmol/L or plasma potassium < 4mmol/L.

Patients who have been diagnosed with PA and had previous aldosterone samples <277 pmol/L, a level which would normally not qualify for confirmatory testing.

Patients with aldosterone results done at different times that indicate variability in production.

Willing to consent and participate in the study.

Disqualifiers

Inability to withdraw β-adrenoceptor antagonist therapy for 2 weeks.

People on end of life treatment.
