Brief Description: The Renal Function Panel test, also known as Kidney Function Panel, is a group of blood tests that assess the function of the kidneys. It provides valuable information about the kidneys' ability to filter and eliminate waste products from the blood, maintain fluid and electrolyte balance, and regulate acid-base levels. This test helps in diagnosing and monitoring kidney-related conditions and diseases.

Also Known As: Kidney Panel Test, Kidney Function Panel Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: Fasting Specimen Preferred

When is a Renal Function Panel test ordered:

A healthcare provider may order a Renal Function Panel test for various reasons, including:

  1. Routine Health Check-up: It is commonly included in routine health check-ups, especially in individuals with risk factors for kidney disease, such as diabetes, hypertension, or a family history of kidney disorders.

  2. Monitoring Chronic Kidney Disease (CKD): Patients with known CKD or those undergoing treatment for kidney conditions require regular monitoring of their kidney function.

  3. Evaluation of Kidney Function: When patients present with symptoms like swelling in the legs, decreased urine output, fatigue, or changes in blood pressure, the Renal Function Panel helps assess kidney function.

  4. Monitoring Medication Effects: Certain medications, like antibiotics or drugs that can affect kidney function, may require monitoring through this test.

What does a Renal Function Panel blood test check for?

A renal panel is a collection of tests that can be used to assess kidney function. To establish the current condition of the kidneys, the tests measure levels of numerous chemicals in the blood, including many minerals, electrolytes, proteins, and glucose.

The kidneys are a pair of bean-shaped organs placed on the right and left sides of the back at the bottom of the ribcage. They filter about 150 quarts of blood per day on average, eliminating waste products from food breakdown and normal cell activity. The kidneys produce urine to evacuate excess water from the body as well as waste materials from the bloodstream.

The kidneys assist in the regulation of pH and levels of essential chemicals in the body, such as potassium, sodium, calcium, phosphorus, chloride, and bicarbonate, by separating them from waste materials and releasing them back into the blood, releasing only as much or as little as is required to maintain normal blood levels.

Waste products can build up in the blood and fluid levels can rise to dangerous levels if the kidneys aren't working properly, causing damage to the body or a potentially life-threatening situation. Kidney injury can be caused by a variety of illnesses and diseases. Diabetes and hypertension are the most common causes of renal disease and major risk factors.

Lab tests often ordered with a Renal Function Panel test:

When a Renal Function Panel is ordered, it's often part of a broader evaluation of kidney health and related systems. Here are some tests commonly ordered alongside it:

  1. Urinalysis:

    • Purpose: To analyze various components of the urine.
    • Why Is It Ordered: To check for abnormalities such as protein, blood, or glucose in the urine, which can indicate kidney disease or other urinary tract issues.
  2. Urine Albumin (Microalbumin) and Albumin-to-Creatinine Ratio:

    • Purpose: To detect small amounts of albumin in the urine, an early sign of kidney damage.
    • Why Is It Ordered: To evaluate for early kidney damage, especially in conditions like diabetes and hypertension where there's a higher risk of kidney disease.
  3. Complete Blood Count (CBC):

    • Purpose: Provides a broad picture of overall blood health.
    • Why Is It Ordered: To detect signs of anemia or infection, which can accompany kidney disease.
  4. Phosphorus and Calcium Levels:

    • Purpose: To measure the levels of phosphorus and calcium in the blood.
    • Why Is It Ordered: To evaluate bone-mineral metabolism, which can be affected in chronic kidney disease.
  5. Parathyroid Hormone (PTH):

    • Purpose: To measure the level of PTH, which regulates calcium and phosphorus levels.
    • Why Is It Ordered: To assess secondary hyperparathyroidism, a condition common in chronic kidney disease.
  6. Liver Function Test:

    • Purpose: To assess liver health.
    • Why Is It Ordered: To rule out liver disease, as some liver conditions can affect or mimic kidney disease.
  7. Blood Glucose and Hemoglobin A1c (HbA1c):

    • Purpose: To measure blood sugar control over time.
    • Why Is It Ordered: Diabetes is a leading cause of kidney disease, so managing blood sugar is crucial for patients with renal impairment.

These tests, when ordered alongside a Renal Function Panel, provide a comprehensive assessment of kidney health and help in the diagnosis and management of kidney disease. They also assist in evaluating potential complications and associated conditions of renal dysfunction. The specific combination of tests will depend on the individual’s symptoms, risk factors, and overall health status.

Conditions where a Renal Function Panel test is recommended:

A Renal Function Panel test is useful in diagnosing and monitoring various kidney-related conditions and diseases, including:

  1. Chronic Kidney Disease (CKD): The test helps evaluate the progression and severity of CKD and monitor the effectiveness of treatments.

  2. Acute Kidney Injury (AKI): It aids in diagnosing and determining the cause of sudden kidney dysfunction.

  3. Diabetic Nephropathy: Patients with diabetes are at risk of kidney damage, and the test can help detect early signs of diabetic nephropathy.

  4. Hypertensive Nephropathy: High blood pressure can lead to kidney damage, and the Renal Function Panel helps assess kidney function in hypertensive patients.

How does my health care provider use a Renal Function Panel test?

A renal panel can be used to assess kidney function, diagnose kidney-related illnesses, screen people who might develop kidney disease, or monitor someone who has already been diagnosed with kidney disease.

A urinalysis, urine protein, or creatinine clearance are some of the various laboratory tests that can be done to monitor kidney function. A urine albumin test, which analyzes small levels of albumin leakage from the blood into the urine, can also be used to detect early kidney impairment in people with diabetes or high blood pressure. An albumin/creatinine ratio can be estimated by measuring both albumin and creatinine in a random urine sample. This might be done to detect how much albumin is escaping from the kidneys into the urine more precisely.

What do my Renal Panel test results mean?

The findings of a renal panel test are not diagnostic; rather, they indicate that there may be a problem with the kidneys and that additional testing is needed to make a diagnosis and determine the reason. The panel's results are usually weighed jointly rather than separately. Individual test results may be abnormal for reasons other than kidney disease, but when combined with risks and/or signs and symptoms, they may indicate the presence of renal disease.

Most Common Questions About the Renal Function Panel:

Understanding the Renal Function Panel Test

What is a Renal Function Panel test?

A Renal Function Panel test is a group of tests performed together to evaluate kidney function. These tests typically include measurements of blood urea nitrogen (BUN), creatinine, glomerular filtration rate (GFR), and electrolytes (like sodium, potassium, and chloride), among others.

Why is a Renal Function Panel test ordered?

A Renal Function Panel test is ordered to assess how well the kidneys are working. This may be done as part of a routine check-up, or it could be ordered if a healthcare provider suspects kidney disease due to symptoms like swelling, frequent urination, fatigue, or nausea.

What aspects of kidney health does the Renal Function Panel test assess?

The Renal Function Panel test assesses various aspects of kidney health, such as how well the kidneys are filtering waste from the blood (through BUN and creatinine measurements), and how they're maintaining the body's balance of electrolytes.

Interpreting Renal Function Panel Test Results

What do high BUN levels in a Renal Function Panel test indicate?

The following is a list of what is included in the item above. Click the test(s) below to view what biomarkers are measured along with an explanation of what the biomarker is measuring.

Albumin

Albumin is a protein made by the liver. A serum albumin test measures the amount of this protein in the clear liquid portion of the blood.

Bun/Creatinine Ratio

A ratio between a person’s BUN and blood creatinine to help determine what is causing these concentrations to be higher than normal. The ratio of BUN to creatinine is usually between 10:1 and 20:1. An increased ratio may be due to a condition that causes a decrease in the flow of blood to the kidneys, such as congestive heart failure or dehydration. It may also be seen with increased protein, from gastrointestinal bleeding, or increased protein in the diet. The ratio may be decreased with liver disease (due to decrease in the formation of urea) and malnutrition.

Calcium

You have more calcium in your body than any other mineral. Calcium has many important jobs. The body stores more than 99 percent of its calcium in the bones and teeth to help make and keep them strong. The rest is throughout the body in blood, muscle and the fluid between cells. Your body needs calcium to help muscles and blood vessels contract and expand, to secrete hormones and enzymes and to send messages through the nervous system.

Carbon Dioxide

CO2 is carbon dioxide. Measures the amount of carbon dioxide in the liquid part of your blood, called the serum. In the body, most of the CO2 is in the form of a substance called bicarbonate (HCO3-). Therefore, the CO2 blood test is really a measure of your blood bicarbonate level.

Chloride

Chloride is a type of electrolyte. It works with other electrolytes such as potassium, sodium, and carbon dioxide (CO2). These substances help keep the proper balance of body fluids and maintain the body's acid-base balance. This is a measure of the amount of chloride in the fluid portion (serum) of the blood.

Creatinine

The creatinine blood test measures the level of creatinine in the blood. This test is done to see how well your kidneys work.

Egfr African American

Glomerular filtration rate (GFR) is a test used to check how well the kidneys are working. Specifically, it estimates how much blood passes through the glomeruli each minute. Glomeruli are the tiny filters in the kidneys that filter waste from the blood.

Egfr Non-Afr. American

Glomerular filtration rate (GFR) is a test used to check how well the kidneys are working. Specifically, it estimates how much blood passes through the glomeruli each minute. Glomeruli are the tiny filters in the kidneys that filter waste from the blood.

Glucose

A blood glucose test measures the amount of a sugar called glucose in a sample of your blood. Glucose is a major source of energy for most cells of the body, including those in the brain. The hormones insulin and glucagon help control blood glucose levels.

Phosphate (As Phosphorus)

This test is performed to see how much phosphorus in your blood. Kidney, liver, and certain bone diseases can cause abnormal phosphorus levels.

Potassium

Potassium is a mineral that the body needs to work normally. It helps nerves and muscles communicate. It also helps move nutrients into cells and waste products out of cells. A diet rich in potassium helps to offset some of sodium's harmful effects on blood pressure.

Sodium

Sodium is a substance that the body needs to work properly it is vital to normal body processes, including nerve and muscle function

Urea Nitrogen (Bun)

BUN stands for blood urea nitrogen. Urea nitrogen is what forms when protein breaks down. BUN measures the amount of urea nitrogen in the blood.
