Renin Assay: Results
Content provided by Healthwise
Results
A renin assay blood test is done to find the cause of high blood pressure (hypertension). The time of day and your position (standing, sitting, or lying down) before the blood sample is collected, your age, and the level of sodium in your blood all affect the test results.
Normal
Normal values may vary from lab to lab.
| Adult, ages 20–39 (upright position, normal-sodium diet): | 0.6–4.3 nanograms per milliliter per hour (ng/mL/hr) or 0.6–4.3 micrograms per liter per hour (mcg/L/hr) |
|---|---|
| Adult, age over 40 (upright position, normal-sodium diet) | 0.6–3.0 ng/mL/hr or 0.6–3.0 mcg/L/hr |
| Adult, ages 20–39 (upright position, low-sodium diet) | 2.9–24.0 ng/mL/hr or 2.9–24.0 mcg/L/hr |
| Adult, age over 40 (upright position, low-sodium diet) | 2.9–10.8 ng/mL/hr or 2.9–10.8 mcg/L/hr |
Many factors can affect renin test results. Your doctor will talk with you about any abnormal results that may be related to your symptoms and medical history.
High values
A high renin value can mean kidney disease, blockage of an artery leading to a kidney, Addison's disease, cirrhosis, excessive bleeding (hemorrhage), or malignant high blood pressure is present.
Low values
A low renin value can mean Conn's syndrome is present.
