How Do They Test For Kidney Disease

How Is A Renal Panel Different From A Comprehensive Or Basic Metabolic Panel

How can I be tested for kidney disease?

There is considerable overlap between the measurements on a renal panel, basic metabolic panel , and comprehensive metabolic panel .

The BMP has 8 components, all of which are included in the CMP, which has a total of 14 measurements. The components of the BMP and CMP are more standardized than the renal panel, which can vary between laboratories.

The BMP, CMP, and most renal panels include measurements of glucose, electrolytes, calcium, and the waste products creatinine and urea nitrogen. The CMP and many renal panels also include measurement of albumin.

An important difference for the comprehensive metabolic panel is its inclusion of tests that help assess the condition of the liver. These are tests found on a typical liver panel test.

Because it is not as standardized, a renal panel test may include measurements, such as phosphorus or the anion gap, that are not found on the BMP or CMP.

Test Results And Stages Of Ckd

Your test results can be used to determine how damaged your kidneys are, known as the stage of CKD.

This can help your doctor decide the best treatment for you and how often you should have tests to monitor your condition.

Your eGFR results is given as a stage from 1 of 5:

  • stage 1 a normal eGFR above 90ml/min, but other tests have detected signs of kidney damage
  • stage 2 a slightly reduced eGFR of 60 to 89ml/min, with other signs of kidney damage
  • stage 3a an eGFR of 45 to 59ml/min
  • stage 3b an eGFR of 30 to 44ml/min
  • stage 4 an eGFR of 15 to 29ml/min
  • stage 5 an eGFR below 15ml/min, meaning the kidneys have lost almost all of their function

Your ACR result is given as a stage from 1 to 3:

  • A1 an ACR of less than 3mg/mmol
  • A2 an ACR of 3 to 30mg/mmol
  • A3 an ACR of more than 30mg/mmol

For both eGFR and ACR, a higher stage indicates more severe kidney disease.

Stages Of Kidney Disease

Medically reviewed by

Chronic kidney disease is divided into five stages. The stages are based on the eGFR test result and how well your kidneys work to filter waste and extra fluid out of your blood. As the stages go up, kidney disease gets worse and your kidneys work less well. At each stage, it is important to take steps to slow down the damage to your kidneys.

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.

You can help lower your risk for CKD or keep it from getting worse by eating healthy, being active, and keeping your blood pressure and cholesterol levels in your target range. Make sure to take care of your kidneys if you are at risk for CKD. If you have diabetes, get tested for kidney disease once each year. Having your kidneys checked regularly gives you the best chance for finding and treating CKD early.

What Do The Stages Of Chronic Kidney Disease Refer To

The five stages of CKD refer to how well your kidneys are working. Kidney disease can get worse in time. In the early stages , your kidneys are still able to filter waste out of your blood. In the later stages , your kidneys must work harder to filter your blood and may stop working altogether.

The goal at each stage of CKD is to take steps to slow down the damage to your kidneys and keep your kidneys working as long as possible.

How Is A Renal Panel Test Different From A Creatinine Clearance Test

A creatinine clearance test includes both a blood and urine sample. The amount of creatinine is measured in each sample, and then the two figures are compared. This comparison provides a method for estimating the glomerular filtration rate and evaluating kidney function.

In contrast, a renal panel uses only a blood sample. While a standard renal panel measures creatinine in the blood, it does not include a urine collection or comparative measurement.

The renal panel also includes a more diverse set of measurements, including proteins, minerals, and electrolytes, than a creatinine clearance test.

How Much Does The Test Cost

Kidney Function Tests, Animation

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.

Can I Take The Test At Home

Very few options exist for a complete renal panel test that can be taken with an at-home test kit. Some at-home kidney tests involve taking a fingerstick blood sample at home and sending it to a lab for analysis, but these tests do not include all of the same measurements that are included in a typical renal panel test.

How Is Kidney Failure Treated

Kidney failure treatment is determined by the cause and extent of the problem. Treating your chronic medical condition can delay the progression of kidney disease. If your kidneys start losing their function gradually, your doctor may use one or more methods to track your health. By watching you closely, your doctor can help you maintain your kidneys function as long as possible.

Your doctor may gauge your kidney function with:

  • Routine blood tests
  • Blood pressure checks

Because the kidneys serve such an important purpose, people in kidney failure need treatment to keep them alive. The main treatments for kidney failure are:

  • Dialysis: This treatment helps the body filter the blood .
  • In hemodialysis, a machine regularly cleans your blood for you. People often receive this kidney failure treatment at a hospital or dialysis clinic, 3 or 4 days each week.
  • Peritoneal dialysis cleans the blood in a slightly different way using a dialysis solution and a catheter. Sometimes, people can do their treatment at home.
  • Kidney transplant: In kidney transplant surgery, doctors place a healthy kidney in your body to take over the job of your damaged organs. This healthy kidney, called a donor organ, may come from a deceased donor or a living donor, who may be a friend or family member. People can live well with one healthy kidney.

    Urine Testing For Excess Protein

    Excess protein may signal a problem. These urine tests help diagnose kidney disease:

    • Urine dipstick a sample of your urine is tested for excess protein or proteinuria. Protein in the urine can be a sign that something is wrong with the kidneys ability to filter the blood properly.
    • Urine culture to check for white blood cells, and bacteria.
    • Urine output measurements the amount of urine you excrete in a day may help your doctor determine the cause of your kidney failure.

    Risk Factors And Medical History

    Your risk of kidney disease increases as you age. Having diabetes or high blood pressure also raises your risk. So does having close relatives who’ve had kidney failure.

    Other conditions that could affect your kidneys include:

    If you have any of these risk factors, your doctor may routinely screen you for kidney disease. That lets your doctor find it as early as possible and slow down its progress.

    Will These Screening Tests Determine Exactly What The Underlying Cause Of The Kidney Disease Is

    Occasionally, specific changes in these screening tests will point to an infectious, inflammatory, or toxic cause for the kidney disease.

    However, because there are many underlying causes of kidney disease, and because the kidneys are able to compensate for damage so well, testing may not tell your veterinarian the exact reasons why the kidneys are malfunctioning. A reduction in kidney function characterized by either a decreased urinary concentrating ability, or an increase in serum BUN and creatinine, is not measurable until two thirds to three quarters of the kidney function is already lost. By this time, many kidney diseases have progressed to a chronic phase and the original cause can no longer be determined. This is one reason why the SDMA test described earlier is important, as it is able to detect subtle kidney disease much sooner.

    Nevertheless, it is still important to evaluate your pet using these tests. Not only will they allow your veterinarian to confirm that the cause of your pet’s clinical symptoms is kidney disease, but they will also allow your veterinarian to choose the most appropriate course of treatment and may indicate if further testing is required.

    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
    • high levels of potassium
    • low levels of salt
    • changes to the levels of calcium and phosphate.

    What Tests Do Doctors Use To Diagnose And Monitor Kidney Disease

    How Chronic Kidney Disease Is Diagnosed

    To check for kidney disease, health care providers use

    • a blood test that checks how well your kidneys are filtering your blood, called GFR. GFR stands for glomerular filtration rate.
    • a urine test to check for albumin. Albumin is a protein that can pass into the urine when the kidneys are damaged.

    If you have kidney disease, your health care provider will use the same two tests to help monitor your kidney disease and make sure your treatment plan is working.

    Common Tests To Help Diagnose Kidney Disease

    Lab work, urine samples, and other tests may be completed as you undergo diagnosis and treatment for renal failure. The test results will be used to assist the healthcare team in evaluating your kidney function and determining the best care plan for you.Remember, you are in control and you are your own best healthcare advocate, so it is essential for you to understand what these tests mean. Note that there can be some differences in these values from one lab to another, so make sure you learn the normal values for your lab. Lets get started.

    Biopsy For Kidney Disease

    A biopsy means that a small piece of tissue is taken for testing in a laboratory. Biopsies used in the investigation of kidney disease may include:

    • kidney biopsy the doctor inserts a special needle into the back, under local anaesthesia, to obtain a small sample of kidney tissue. A kidney biopsy can confirm a diagnosis of chronic kidney disease.
    • bladder biopsy the doctor inserts a thin tube into the bladder via the urethra. This allows the doctor to view the inside of the bladder and check for abnormalities. This procedure is called a cystoscopy. The doctor may take a biopsy of bladder tissue for examination in a laboratory.

    Your doctor may arrange other tests, depending on the suspected cause of your kidney disorder.
