The Serum Renin Test measures renin levels to assess kidney function and diagnose conditions related to blood pressure regulation and adrenal function.

You may need to avoid certain foods, activities, or medications before the test. Follow specific instructions from your healthcare provider for accurate results.

The test is often performed in the morning, as renin levels can vary throughout the day. Timing instructions will be provided by your healthcare provider.

Elevated or decreased renin levels can indicate conditions such as secondary hypertension, kidney disorders, or adrenal dysfunction. Further evaluation may be needed.

Results are generally available within 24 to 48 hours after the blood sample is collected, allowing for prompt review and diagnosis.

A high ratio may indicate proteinuria, which can be a sign of kidney damage or disease.

No special preparation is typically required, but it’s important to inform your healthcare provider about any medications you are taking.

A urine sample is collected in a clean container. No fasting or special dietary restrictions are needed.

The test is highly accurate in assessing kidney function and detecting proteinuria when performed correctly.

Abnormal results should be discussed with your healthcare provider, who will recommend further tests or treatment based on your overall health and symptoms.

Preparation may include pre-operative blood tests, imaging studies, and discussions with your surgical team about the procedure and recovery process.
