About This Test
Renin is a proteolytic enzyme released from juxtaglomerular cells of the kidney. The enzyme cleaves a substrate to produce Angiotensin I which in turn produces Angiotensin II. This metabolite plays a key role in various forms of hypertension. Increased levels are seen in Renal hypertension, Addison’s disease and Secondary hypoaldosteronism. Low levels are detected in Hyporeninemic hypoaldosteronism and Primary aldosteronism.

Frequently Asked Questions
Outsourced test are being done from Dr. Lal Path Lab. Charges and reporting time is same as of Dr. Lal Path Labs.
Patient should be ambulatory / upright 2 hours prior to the test. Drug interactions to be noted: Potassium wasting diuretics, Spironolactone, Eplerenone, Amiloride and Triamterene should be dicontinued at least for 4 weeks; Adrenergic blockers, Clonidine, Methyldopa, NSAIDs, Angiotensin-converting enzyme inhibitors, Angiotensin receptor blockers, Renin inhibitors and Dihydropyridine calcium channel antagonists should be discontinued for 2 weeks. If necessary to maintain hypertension control, patients should be treated with other antihypertensive medications like Verapamil slow-release, Hydralazine, Prazosin, Doxazosin & Terazosin that have lesser effects on Plasma renin levels. Any change in medication should be done in consultation with treating clinician.
The Plasma Renin test is important because it helps evaluate the renin-angiotensin-aldosterone system (RAAS), which regulates blood pressure and fluid balance, and aids in diagnosing certain forms of hypertension and kidney disorders.
TAT Policy
The Turnaround Time (TAT) depends on the following factors:
- Registration date and time
- Type of scan or test
- Scan time or sample collection time
In uncommon circumstances, TAT may be delayed due to test complexity or reasons beyond our control. You will be informed of the estimated TAT at the time of registration.
