WebThe renin–angiotensin–aldosterone system (RAAS) is a critical regulator of blood volume and systemic vascular resistance on a long-term basis. The baroreceptor reflex, on the other hand, responds in a short-term manner to decreased blood pressure. Arterial baroreceptors inform your autonomic nervous system of minor or rapid beat-to-beat ... WebA high ratio of serum aldosterone (SA) in ng/dL to plasma renin activity (PRA) in ng/mL per hour, is a positive screening test result, a finding that warrants further testing. A SA:PRA ratio ≥20 and SA of ≥15 ng/dL indicates probable primary aldosteronism.
