Sample Type: Plasma
Tests Included:
Plasma Renin Activity
Sample Required:
Blood sample, usually collected in a special tube containing renin inhibitor.
Test Time:
Results are typically available within a few days.
Test Range Values:
Normal range for plasma renin activity levels varies but is generally between 0.25 to 5.82 nanograms per milliliter per hour (ng/mL/h).
What is the test?
Plasma Renin Activity measures the activity of renin, an enzyme involved in regulating blood pressure and kidney function, aiding in the diagnosis of hypertension and certain kidney disorders.
Test Procedure:
A blood sample is collected in a special tube containing a renin inhibitor, preserving the renin activity, and analyzed in the laboratory.
When to take the test:
When a healthcare provider suspects primary aldosteronism, renovascular hypertension, or certain kidney disorders, they may order a plasma renin activity test.
Who should take the test:
Patients with high blood pressure, electrolyte imbalances, or kidney disorders may require this test.
Precautions for exceptional cases (pregnancy, etc.):
Pregnant individuals may have specific guidelines regarding this test, which their healthcare provider will communicate.
Frequently Asked Questions:
Q1: What can cause high plasma renin activity levels?
A: High plasma renin activity can result from conditions like renal artery stenosis, heart failure, or certain medications affecting the renin-angiotensin-aldosterone system.
