What Do The Results Of My Kidney Function Test Mean
Kidney function test results can tell you whether your kidneys are functioning typically or not. Most function tests look for two measurements:
- GFR of less than 60 could indicate kidney disease.
- Urine albumin-to-creatinine ratio of more than 30 milligrams per gram could be a warning sign of kidney disease.
Why Would I Need This Test
- they suspect your kidneys are not working properly
- you have kidney disease and your treatment is being monitored
- your doctor is concerned about the levels of potassium or other minerals in your blood
- you are taking medication that might affect your kidneys
What To Expect After Blood Tests
Once the needle is withdrawn, youâll be asked to apply gentle pressure with a piece of gauze or bandage to the place where the needle was inserted. This helps stop bleeding. It also helps prevent swelling and bruising.
Most of the time, you can remove the pressure after a minute or two. You may want to keep a bandage on for a few hours.
Usually, you donât need to do anything else after a blood test. Results can take anywhere from a few minutes to a few weeks to come back. Your doctor should get the results. Itâs important that you follow up with your doctor to discuss your test results.

How Much Does The Test Cost
There is no universal fixed price for a renal panel test.
Different charges that can figure into the total price include office visits, fees related to the blood draw procedure, and costs of laboratory analysis. How much is billed for these charges can depend on several factors including:
- Where the blood draw is performed
- The laboratory that performs the testing
- The specific measurements included in the renal panel
- Whether you have health insurance
Many health insurance plans will cover some or all of the costs of a renal panel if the test is prescribed by your doctor, but some costs, such as for a deductible or copays, may still have to be paid out of pocket.
For more detailed information about what will be covered and your expected costs, talk directly with your doctors office and your health insurance company.
Estimated Glomerular Filtration Rate
Estimated glomerular filtration rate provides a guide to kidney function. Although the level of creatinine in the blood is a useful guide to kidney function, the eGFR is a more accurate measure. Blood creatinine can be used to estimate the eGFR using age, sex and race. This is often calculated by computer and reported with the creatinine blood test. The normal value for eGFR is 90-120 ml/min. An eGFR below 60 ml/min suggests that some kidney damage has occurred. The value becomes lower with increasing severity of kidney damage.

Why Might I Need A Kidney Function Test
Some conditions, such as diabetes or high blood pressure , affect how well the kidneys work. If you have one of these conditions, your healthcare provider may use kidney function tests to help monitor these conditions.
You may also need a kidney function test if you have symptoms that indicate possible kidney problems. These symptoms might include:
- Blood in your urine .
- Problems with starting to pee.

Testing For Kidney Disease In Your Dog Or Cat
A large number of older dogs and cats develop kidney disease or failure. With correct diagnostic testing, the problem can be caught early enough for more successful treatment.
Kidney disease and failure is one of the most common disorders I see in dogs and cats. Its extremely prevalent as animals age, especially in those eight years of age and up. While it can be fatal, kidney disease can usually be treated and even cured if caught early. Lets look at the testing that allows for the early diagnosis of this frequently-seen health problem in dogs and cats.
Ways to Test for Kidney Disease
The BUN is one of three blood tests for kidney function. It is a good screening test but not perfect, as it only elevates significantly if kidney function is destroyed by 60% to 70%. However, it is inexpensive to run and part of most blood panels. BUN is also affected by diet, exercise, and muscle mass, so results can be skewed due to non-kidney factors increased results must be interpreted in light of these factors.
Therefore, a third test called SDMA , which tests for the amino acid arginine, may be incorporated into the blood panel. SDMA levels elevate very early in the course of kidney disease, anywhere from 12 to 36 months before BUN and creatinine elevate .

How Is A Renal Panel Different From A Kidney Profile Test
The renal panel and kidney profile are designed to assess kidney health. However, there are important differences between them.
The renal panel is only a blood test, and it includes a combination of measurements that can vary based on the laboratory.
In contrast, the kidney profile is a standardized series of two different tests. It includes a blood test for the estimated glomerular filtration rate and a urine test to measure albumin and the albumin-to-creatinine ratio.
While eGFR is calculated on some renal panel tests, it is always included in the kidney profile test. The kidney profile also adds a second test component by measuring urine albumin, which can be an indicator of chronic kidney disease.
This specific two-part kidney profile test was formalized in 2018 through collaboration by professional medical organizations, advocacy groups, and laboratories to enhance the detection of kidney disease. When appropriate, the kidney profile can be ordered along with a renal panel to obtain a wider range of measurements related to kidney health.
What Are The Signs Of Kidney Cancer
Often, there are no signs or symptoms of kidney cancer, especially in its early stages.
Kidney cancer is often found during routine blood work or testing for other concerns. When symptoms are present, they can look like symptoms of less serious conditions, like bladder infections or kidney stones.
Symptoms of kidney cancer may include:

Urine Tests For Kidney Disease
Damaged or inflamed kidneys leak substances such as blood or protein into the urine. The preferred test for detecting protein in the urine is a urine albumin-to-creatinine ratio test, which shows the amount of albumin in the urine.
A urine ACR test should be done at least once a year if the person has diabetes or high blood pressure, and every two years if the person has any of the other identified risk factors for developing chronic kidney disease.
A urine ACR test is performed by sending a sample of your urine to a laboratory for analysis.
What Tests Are Most Often Used To Diagnose Kidney Cancer
Blood tests are not enough to diagnose kidney cancer. If your doctor suspects kidney cancer, youll likely have a range of other tests to confirm your diagnosis. This often includes:
- CT scan. A CT scan uses multiple X-ray images to create detailed images of your kidneys so doctors can look for tumors and other issues.
- MRI. An MRI uses magnetic imaging to create images of your kidney to check the size, shape, and location of any tumors.
- Ultrasound. An ultrasound uses sound waves to create images of your kidneys. It can help locate tumors and whether they are benign or cancerous.
- Bone scan. A bone scan can be done to see the inside of your bones. Your doctor might do this test if they suspect cancer has spread to your bones.
- Biopsy. During a biopsy, a small piece of your kidney is removed with a needle so it can be tested in a lab. Biopsy results can confirm cancer and help diagnose the stage of the tumor.
- Renal angiography.This test helps your doctor see the blood supply to your kidneys in detail. Blood supply to a tumor, if present, is also able to be seen here.
- Intravenous pyelogram. This test requires dye to be injected into a vein so the kidneys are more visible via X-ray. This is another way an obstruction or tumor can be detected.
Blood Tests For Kidney Disease
The best measure of kidney function is the glomerular filtration rate , which can be estimated from a blood test that checks the blood for creatinine .
A normal GFR result is higher than 90 mL/min/1.73 m2. If the result is persistently less than 60 mL/min/1.73 m2 for at least three months, this confirms that the person has chronic kidney disease.
Blood tests can reveal other abnormalities of kidney function, such as:
- high levels of acids
- changes to the levels of calcium and phosphate.
Taking Control Of Your Kidney Health
The only way to know whether you have any stage of kidney disease is to undertake a Kidney Health Check with a doctor. Going for checks regularly is key to early detection this empowers you to slow the progression of end-stage kidney disease if you are diagnosed. This can also make a huge difference to living your life to the fullest with kidney disease.

How Is A Cmp Done
Most blood tests take a small amount of blood from a vein. To do that, a health professional will:
- put an elastic band above the area to get the veins to swell with blood
- insert a needle into a vein
- pull the blood sample into a vial or syringe
- take off the elastic band and remove the needle from the vein
In babies, blood draws are sometimes done as a âheel stick collection.â After cleaning the area, the health professional will prick your babyâs heel with a tiny needle to collect a small sample of blood.
Collecting a sample of blood is only temporarily uncomfortable and can feel like a quick pinprick.
Why Have A Kidney Test
The government recommends that everyone at high risk has a test for kidney disease every year. This will mean that more people with kidney disease will be identified when the disease is still at an early stage. This is important because:
- Treatment of mild-to-moderate kidney disease with medicines and changes in lifestyle can slow down kidney damage and avoid or delay the need for kidney dialysis or a kidney transplant.
- Earlier diagnosis of advanced kidney disease improves the success rate of dialysis and transplant.
- Early detection and treatment of kidney disease lessens the chance of it leading to heart disease.
- Kidney disease is common and it’s affecting more and more people. The number of people receiving dialysis or a transplant for kidney failure in England is expected to rise by 50% in the next 10 years.

Why Is It Important To Check Kidney Function
When your kidneys do not work as they should, waste can build up in your blood. This can make you sick. If you have long-term kidney disease, you may not have any symptoms until your kidney function is very low.
Blood and urine tests can help show how well your kidneys are working. They can help your doctor know:
- If the disease started all of a sudden or if you have had it a long time.
- The cause of the kidney damage.
- The best type of treatment to slow the damage.
- How well treatment is working.
- When to begin dialysis or have a kidney transplant.

The Incidence Of Kidney Disease Is Rising Screen Your Kidney Function With These Simple Blood And Urine Test
Written by Shraddha Rupavate | Updated : August 27, 2014 11:10 AM IST
Kidney problems do not develop overnight. Your kidney function naturally starts declining after you cross your 30s. And whether you will develop a kidney problem later in life is largely dependent on your lifestyle habits and diet. In most cases, kidney problems are caused as a result of a primary condition like diabetes, hypertension or high cholesterol levels. Because the symptoms of kidney diseases are not evident unless the kidneys are deteriorated to a great extent , you should regularly screen your kidney function . Here are some kidney function tests that can determine whether you are at a risk of kidney disease.
1. Blood pressure: Your kidneys perform the function of filtering blood under pressure to eliminate waste products through the urine. If your blood pressure is higher than normal it will increase the load on your kidneys and may lead to kidney disease. Alternatively, a person is suffering from kidney disease is also likely to have high blood pressure. Read more about the medication for high blood pressure.
2. Blood creatinine test: Creatinine is a waste product that is produced by your muscles. It enters the bloodstream and is filtered by the kidneys to get excreted through the urine. A blood creatinine test will measure the amount of creatinine in your blood. A higher level may indicate that the kidneys are not functioning properly.

What Causes Kidney Malfunction
A major culprit of kidney problems is an acidic diet . A brand-new study sheds light on the renal problems that can be caused by a high-acid, meat-rich diet.
The study followed 1,500 people with kidney disease for a period of 14 years. Participants who ate a diet high in meat came very close to experiencing complete kidney failure, while those who ate more fruits and vegetables did not even come close to kidney failure. Researchers estimate that an acidic diet can make it three times more likely for your kidneys to fail.1
Says lead study author Dr. Tanushree Banejee,
Patients with chronic kidney disease may want to pay more attention to diet consumption of acid rich foods to reduce progression to kidney failuredialysis treatmentsmay be avoided by adopting a more healthy diet that is rich in fruits and vegetables.1
