Renin Direct

The Plasma Renin Direct test is conducted to measure the levels of renin in the plasma. Renin is an enzyme produced by the kidneys that plays a crucial role in regulating blood pressure and fluid balance in the body. The renin activity test helps in diagnosing conditions related to renal function and hypertension.

The plasma renin activity test may be prescribed in the following cases:

• Patients with hypertension
• Patients with low potassium levels
• Patients who are taking treatment for hypertension but whose BP is uncontrollable.
• Those who experience symptoms like headache, high blood pressure, weakness, dehydration, joint pain, stomach ache, etc.

Renal dysfunction or hypertension can present with the following symptoms:

• High blood pressure: Persistent high blood pressure can be a symptom of kidney disease or hypertension.
• Frequent urination: Increased frequency of urination may indicate underlying kidney problems.
• Edema: Swelling in the legs, hands, or face can occur due to fluid retention caused by kidney dysfunction.
• Fatigue and weakness: Decreased kidney function can lead to fatigue and weakness due to reduced production of erythropoietin, a hormone crucial for red blood cell production.
• Changes in urine colour and volume: Abnormal urine colour, decreased urine output, or foamy urine may indicate kidney problems.

To perform the plasma renin test, a sample of whole blood is collected using an EDTA tube. The healthcare professional will clean the area with an antiseptic solution and insert a needle into a vein to draw the required amount of blood. The collected sample is then sent to the laboratory for analysis.

In the laboratory, the collected blood sample is processed to separate the plasma from other components. The plasma is then analyzed using specialized equipment to measure the concentration of renin. The results are reported in units per litre (U/L) or picograms per millilitre (pg/mL).

If a positive result indicates renal dysfunction or uncontrolled hypertension, it is important to consult a healthcare professional for further evaluation. Treatment options may include lifestyle modifications such as a healthy diet, regular exercise, and weight management. Medications may also be prescribed to control blood pressure or manage underlying conditions causing renal dysfunction.

The benefits of an early diagnosis include:

• The renin activity test conducted by Apollo 24|7 ensures accurate and reliable results, providing insight into renal function and blood pressure regulation.
• Early and timely diagnosis allows the detection of renal dysfunction or hypertension early, which enables timely intervention and management, preventing further complications.
• Early detection of renal dysfunction or hypertension enables healthcare professionals to closely monitor the condition, preventing or managing complications effectively.
• The Plasma Renin Direct test helps in determining the underlying cause of high blood pressure, guiding personalised treatment strategies.
• With early diagnosis, healthcare professionals can develop personalized treatment plans tailored to individual needs, optimizing health outcomes.
