Introduction to Renal Function Test (RFT)

RFT, short for Renal Function Test, is a series of tests that aim to check how well your kidneys are working and detect abnormalities (if any) to take charge while there is still time. Renal, also called the Kidney, are bean-shaped organs that are important for our health in so many ways. From removing waste products from the blood and producing urine to controlling several substances in the blood, Renal or Kidney controls all. Therefore, proper functioning is a must for your well-being. Doctors often suggest the Renal Function Test (RFT), commonly known as the Kidney Function Test (KFT), to measure certain substances in the blood to detect abnormalities (if any) and determine the functioning of the kidney. It mainly checks how efficiently your kidneys are removing waste from your system.

Since kidney health is important, keeping track of its functioning should not be ignored. Whether you have symptoms indicating a problem with renal or the test is suggested as a part of a routine checkup, it is advisable to get tested to track your kidney health and avoid possible complications.

What symptoms indicate a Kidney Problem?

Well, if you have any of the following signs or symptoms, it could indicate that your renal system might not be working fine and that you need immediate attention. Such symptoms that indicate the Renal problems are:

• If you feel more tired, have less energy, or are unable to concentrate, it could be due to deteriorated kidney health. This is because a decrease in normal renal function can build up toxins and impurities in the blood, leading to these symptoms.
• Moreover, having dry and itchy skin is yet another sign that your kidneys are failing to balance the minerals and nutrients in the body.
• If you feel the urge to urinate more often, especially at night, it could be an indicator of compromised renal health.
• Also, if there is blood in urine, its consistency, color, or odor has changed all of a sudden, you should better get it checked to confirm the problem.
• If you have persistent puffiness around your eyes or your ankles and feet are swollen, it could be a sign of a kidney problem.
• A poor appetite due to the buildup of toxins is another sign of reduced kidney function.
• Lastly, muscle cramping can also result from impaired renal functions that need to be diagnosed at the earliest.

According to statistics, around 10% of the Indian Population suffers from CKD, and approximately one lakh renal failures are reported every year. Therefore, recognizing the signs and taking action in time is crucial to prevent complications and take charge of your renal function. So, if you have any of the above symptoms or risk factors, it is essential to get tested as soon as possible. Book a Renal Function Test today.

Risk factors for Renal Disease

There are not just one or two but several risk factors associated with renal disease, such as:

• Your gender is the foremost factor increasing your risks, as some study suggests that kidney problems are more prevalent among men than women.
• Moreover, individuals with a family history of renal disease are at the most risk and need to be tested routinely.
• If you have a history of hypertension, diabetes, or any other chronic illness, you may be at the risk of kidney disease than healthy individuals.
• If you smoke or use tobacco, you are putting your kidney health at risk, as it can shoot your blood pressure up, which can lead to kidney problems.

So, if you think you are at risk or have symptoms, don’t overlook them, as they can lead to renal complications. Book Renal Function Blood Test with Redcliffe Labs today.

• There is no need to fast, but it is advisable to consult your doctor regarding the same, especially if you are having a special diet.
• If taking any medicine or supplements, prescribed or non-prescribed, discuss it with your doctor to ensure it doesn’t interfere with your test results.
• Avoid rigorous exercise, smoking, or alcohol consumption for a certain period before the test.
• Do not panic; if you have any known pregnancy or medical condition, inform your doctor before the test.

Follow the instructions to ensure the test is done appropriately and reports are accurate. If you have any doubts, discuss them with your doctor before the test and follow their instructions accordingly.

What happens during a Renal Function Test?

For A Blood Test:

• A phlebotomist may tie a band around your arm and clean the site.
• After cleaning, they may ask you to make a fist to make the vein more visible.
• Once the vein is located, they insert a sterile syringe to draw the blood, which may cause discomfort or slight pain.
• After collecting the blood, the syringe will be removed, and the site will be covered using a cotton ball or a bandage.

For A Urine Test:

• A phlebotomist may hand over the sterile container and instruct you to collect the urine sample.
• Make sure to keep your hands clean and avoid direct touch with the sample.
• Seal the container properly before handing it over to the phlebotomist to protect the sample.

Follow all their instructions thoroughly, and if you have any doubts, clear them before the sample collection. Our phlebotomists at Redcliffe Labs are well-trained and can guide you correctly.

Common Renal Function Tests

These are the most common tests included in renal function testing. Let's take a closer look at them to comprehend their functions and purposes. 

• Blood Urea Nitrogen (BUN) and Serum Creatinine: These tests check the amount of urea nitrogen and level of creatinine in the blood, providing information about kidney and liver function. 
• Albumin levels in the blood help provide insights into kidney health. High albumin levels may indicate kidney damage; low albumin levels can indicate liver disease or malnutrition. 
• Glomerular Filtration Rate (eGFR): A low eGFR indicates reduced kidney function. 
• Urinalysis: This part is crucial as it detects whether protein, blood, and other substances are present in the urine. If they are, this can lead to kidney damage or disease. 
• Tests for Waste Products: Healthy kidneys help filter out the urea and creatinine from the blood and eliminate it through urine. If this doesn't happen, this can lead to the collection of urea and creatinine in the bloodstream. 
• Sodium and Potassium Levels: Sodium and potassium levels in the bloodstream are also tested through renal function tests to ensure the kidneys filter them out properly. 
• Mineral Tests are performed to monitor phosphorus and calcium levels. This helps maintain the body's acid balance and the proper functioning of the muscles, nerves, brain, and heart. However, high levels may indicate kidney disease.

Role of Renal Function Tests

Renal function tests play an important role in hypertension, pregnancy, medication monitoring, and athletes, which are described below: 

Renal function tests in hypertension

Individuals with hypertension are at a high risk of getting kidney disease. It poses a threat to kidney health by damaging their kidneys. High BP can narrow the blood vessels, leading to damage and making them weak throughout the body. 

Early detection through RFTs can help protect kidney health and allow for personalized treatment plans. 

Renal function tests in pregnancy

Renal function tests play a crucial role in pregnancy. It is a transformation phase for a mom-to-be and poses challenges to kidney function, including preeclampsia or gestational disease. The tests play a key role in monitoring the health of pregnant individuals and avoiding complications. 

Renal function tests in athletes

These tests are relevant for athletes, especially those who incorporate creatinine and protein powders into their diets to enhance their performance. These supplements can pose certain risks to kidneys, and RFTs are instrumental in detecting the problem and safeguarding kidney health. 

Renal function tests in medication monitoring

Renal function tests help monitor medication, especially when cancer treatment through chemotherapy is involved. These tests help assess the safety of medications and check for their benefits. 

7 key reasons kidney health is important 

Listed below are the seven best reasons underlying the importance of kidney health: 

1. It filters waste and toxins: The kidneys filter toxins from the blood and extra water to make urine. This is essential for the kidneys to function properly, ensuring waste products like urea and creatinine do not build up in the blood, which can cause life-threatening conditions like uremia. 
2. Responsible for fluid and electrolyte balance: Kidneys help regulate water composition and maintain the balance of water, sodium, electrolytes, and potassium. Imbalance can cause problems like dehydration, high BP, or electrolyte imbalances. 
3. Regulate blood pressure: Healthy kidneys help regulate blood pressure by controlling the body's fluid levels and producing hormones such as renin. Poor kidney functioning can lead to high blood pressure (BP), and conversely, this situation can damage them. 
4. Helps produce red blood cells: Healthy kidneys produce erythropoietin or EPO. This hormone stimulates the bone marrow to produce red blood cells (RBCs). If the kidneys are not functioning properly, this process slows down and leads to anemia. 
5. Bone Health: Vitamin D is essential for calcium absorption and bone health. Hence, healthy kidney function is important. If kidneys are not working properly, this can lead to weakened bones and increase the risk of fractures and osteoporosis. 
6. Support the function of other organs: Healthy kidneys successfully work with organs such as the liver, heart, and brain. Impaired kidneys can potentially contribute to cardiovascular diseases, liver dysfunction, or neurological problems. 
7. Prevention of kidney disease: Maintaining kidney health is crucial to preventing chronic kidney disease (CKD), including kidney failure. Early detection and timely intervention can help prevent CKD progression to end-stage renal disease. 

In short, kidneys support many essential functions, including the ones listed above. Maintaining kidney health is crucial and can be done by adopting healthy habits such as staying hydrated, eating a balanced diet, and avoiding too much medication. This will help reduce the risk of kidney-related diseases.

What are the benefits of Renal Function Testing? 

Renal function testing (RFT) helps evaluate kidney function. Early detection of kidney issues through these tests can delay the progression of chronic kidney disease and related complications. 

Top 8 Benefits of Renal Function Testing: 

The renal function testing is important because: 

• Helps early detection of kidney disease: One of the primary roles of renal function testing is to identify early signs of kidney damage or dysfunction, sometimes even before the symptoms appear. Early diagnosis helps manage and slow down the progression of CKD, potentially preventing kidney failure. 
• Monitors existing kidney conditions: Renal function tests (RFT) are crucial for individuals with diabetes, high blood pressure, kidney disease, or conditions that can affect kidney function. The test is performed to monitor disease progression and check whether changes are needed in treatment plans. 
• Provides insights into overall kidney health: The RFT assesses overall kidney health. It measures how efficiently kidneys filter waste and maintain the balance of electrolytes and fluids. This is crucial for individuals with diabetes, hypertension, or genetic kidney disorders. 
• Detects acute kidney injury: Acute kidney injury can happen due to infections, medication side effects, or dehydration. Blood urea nitrogen (BUN) and serum creatinine are included in renal function testing and help detect acute kidney injury. 
• Monitors effectiveness of treatment: Renal function tests allow healthcare providers to check whether the treatments for kidney disease are working effectively. If needed, they can adjust the treatment plans. 
• Preoperative assessment: Renal function tests help doctors evaluate the patient's kidney health. Medical procedures such as imaging scans or surgeries can pose risks to individuals with impaired kidney function, thus minimizing the risk of complications. 
• Prevents Kidney Failure: Regular renal function tests can prevent or delay the onset of kidney failure, particularly in people at high risk for kidney disease. 
• Routine health check-ups: Kidneys decline with age. Regular testing can monitor this decline and ensure your kidneys stay within healthy ranges. Renal function tests are part of routine health screenings. Early intervention can minimize kidney-related complications and improve kidney health in older adults.
