Renin Activity Plasma Test

A Plasma Renin helps determine the cause of hypertension in cases where signs of kidney disease are present.

Sample Report

Test Code: 002006

Also Known As: Plasma Renin Activity (PRA); PRA

Methodology: The renin in plasma is allowed to act on the plasma's endogenous substrate, angiotensinogen producing angiotensin I. This is measured by liquid chromatography/mass spectrometry (LC/MS-MS).

Preparation: No fasting required. If possible, medications should be stopped 3 weeks prior to collection. Check with physician before stopping any medications. It is recommended that the patient be ambulatory for at least 30 minutes before blood collection.

Test Results: 2-3 days. May take longer based on weather, holiday or lab delays.

Sample Report

Test Code: 16846

Also Known As: Plasma Renin Activity (PRA); PRA

Methodology: Liquid Chromatography/Tandem Mass Spectrometry (LC/MS/MS)

Preparation: No fasting required. If possible, medications should be stopped 3 weeks prior to collection. Check with physician before stopping any medications. It is recommended that the patient be ambulatory for at least 30 minutes before blood collection.

Test Results: 5-7 days. May take longer based on weather, holiday or lab delays.

Description

A plasma renin may be ordered when a patient has high blood pressure and low potassium. Even if potassium is normal, testing may be done if typical medications do not control the high blood pressure or if hypertension develops at an early age. Primary aldosteronism is a potentially curable form of hypertension, so it is important to detect and treat it properly.
