78960-2

LOINC code 78960-2 identifies "Aldosterone and renin concentration panel - Plasma". The aldosterone to renin ratio (ARR) can be determined by dividing the molar concentration of aldosterone [LOINC: 14586-2] divided by the mass concentration of renin (also known as active renin concentration or 'ARC') [LOINC: 35570-1]. ARR results above 130 pmol/ng indicate primary aldosteronism. ARR results between 100 - 130 pmol/ng are indeterminate and suggest a need for repeat testing.[PMID: 21912488] The ARR can also be determined by dividing the mass concentration of aldosterone by the renin activity in blood plasma [LOINC: 55151-5].[PMID: 15483077]

This code measures Aldosterone & renin concentration panel in Plas. It belongs to the PANEL.CHEM class in the LOINC classification.

LOINC (Logical Observation Identifiers Names and Codes) is a universal standard for identifying laboratory and clinical observations. It is maintained by the Regenstrief Institute and used worldwide for health data exchange.
