Description
EDTA Plasma, NA, Fasting or Non Fasting: As suggested by doctor
Sample Required:
The Plasma Renin Activity (PRA) Test requires a blood sample. A healthcare professional will draw blood, typically from a vein in the arm.
Test Time:
The results of the PRA Test are usually available within a few days after the blood sample is collected. The exact turnaround time may vary depending on the laboratory.
Test Normal Range:
The normal range for Plasma Renin Activity can vary between laboratories. Typically, normal values fall within the range of 0.2 to 2.3 nanograms per milliliter per hour (ng/mL/hr).
What is the Test?
To collect a blood sample, a healthcare expert will clean the area, generally the arm, and inject a needle into a vein. Renin is essential for maintaining blood pressure and fluid balance in the body. Abnormal PRA levels may indicate underlying kidney or hormonal disorders, such as primary aldosteronism or renovascular hypertension.
Test Procedure:
A healthcare expert will clean the area, usually the arm, and put a needle into a vein to take a blood sample. The blood sample is then sent to a laboratory for analysis. In the laboratory, the blood sample is tested to determine the activity of renin.
When to Take the Test:
The PRA Test is typically ordered when a healthcare provider suspects or wants to evaluate conditions related to blood pressure regulation, such as primary aldosteronism or renovascular hypertension. It is also used in research and monitoring the effectiveness of treatment for these conditions.
Who Should Take This Test:
Individuals with uncontrolled high blood pressure, low blood potassium levels, or other signs of hormonal imbalances related to blood pressure regulation may be candidates for the PRA Test. Additionally, those with known primary aldosteronism or renovascular hypertension may undergo this test as part of their diagnosis and management.
Precautions for Exceptional Cases (Pregnancy, etc.):
There are generally no specific precautions related to pregnancy for this test. However, pregnant individuals with hypertension or related conditions should work closely with their healthcare providers to manage their condition during pregnancy.
