Reference Range for Aldosterone [CLEIA]/Renin Concentration Ratio and Aldosterone [CLEIA]/Renin Activity Ratio
Aldosterone [CLEIA] (pg/mL)
4.0-82.1
Renin concentration (ARC) [CLEIA] (pg/mL)
2.21-39.5
Renin activity (PRA) [EIA] (ng/mL/hr)
Recumbent position 0.2-2.3
Sitting position 0.2-3.9
Standing position 0.2-4.1
Aldosterone [CLEIA]/renin concentration ratio
Less than 20
Aldosterone [CLEIA]/renin activity ratio
Less than 100
*Criteria of positive judgements are concentration ratio ≥40 or
activity ratio ≥200 and plasma aldosterone concentration ≥60pg/mL.
However, in the cases of concentration ratio less than 20-40 or
activity ratio less than 100-200 and plasma aldosterone concentration ≥ 60 pg/mL
of the "ARR borderline", the result is provisionally considered positive.
*If the result is provisionally positive,
it is stated that the need for a functional confirmation test will be considered on an individual basis,
taking into account the patient's needs and clinical findings,
particularly the presence or absence of hypokalemia or adrenal tumors, as well as the patient's age.
