What Do The Results Of My Kidney Function Test Mean

Renal Function Blood Test – What does it mean?

Interpreting blood test results can be difficult. Your doctor or nurse will contact you if there is anything that needs discussing or further action is needed. Increased creatinine levels in your blood suggest diseases that affect kidney function such as:

  • diabetic kidney disease
  • pyelonephritis
  • urinary tract obstruction, or reduced blood flow to your kidneys due to shock, dehydration, congestive heart failure, atherosclerosis or complications of diabetes.

High urea levels suggest impaired kidney function. This may be due to acute or chronic kidney disease. However, there are many things besides kidney disease that can affect urea levels, such as dehydration, decreased blood flow to your kidneys as in congestive heart failure, shock, stress, recent heart attack or severe burns, bleeding from your gastrointestinal tract, conditions that cause obstruction of urine flow.

How To Calculate Your Gfr

Explaining Your Kidney Test Results: A Tear

Estimating GFR begins with a simple serum creatinine blood test. If youre using our GFR calculator, your eGFR is calculated using the results of your blood test, along with your age, ethnicity, and gender. When your eGFR is calculated by your doctor, weight and body size may also be factored into your eGFR.

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.

Questions For Your Doctor About Test Results

When your test results are ready, you can learn more about their significance by discussing them with your doctor. Some questions that you can ask include:

  • Were there any abnormal findings on my renal panel test? If so, what were they?
  • For any abnormal findings, can you explain what might be the cause?
  • Are there any follow-up tests that are warranted based on my renal panel test?
  • Should I take this test again? If so, when?

What Does The Test Measure

A renal panel includes multiple measurements. However, not all renal panel tests are exactly the same. The components can depend on the laboratory or the measurements requested by the doctor prescribing the test.

The most common components tested in most renal panels include:

Other measurements that may also included in a renal panel include:

  • Anion gap: The anion gap is a comparison of different electrolytes. Specific electrolytes can be positively or negatively charged, and this test assesses the balance between the two types. This measurement helps determine if you have too much or too little acid in your blood.
  • Estimated glomerular filtration rate : The eGFR is an evaluation of kidney function. Glomeruli are tiny filters in the kidneys, and the eGFR is a calculation of how much blood they are filtering every minute. There are different ways to calculate eGFR, but most tests use a special formula based on your creatinine level.
  • Total protein: There are several kinds of proteins that can be found in the blood, and total protein is a count of all of them. These proteins include albumin and multiple types of globulins, which are made by the immune system.
  • BUN-to-creatinine ratio: In some cases, comparing the amounts of the waste products BUN and creatinine can provide information about whether abnormal levels are being caused by problems in the kidneys or another part of the body..

Understanding Your Lab Values

Liver Function (LFT) Blood Test – What does it mean?

People who develop chronic kidney disease may have some or all of the following tests and measurements. If you have kidney disease ask your doctor which tests you will have and how often they will be done. Speak to your doctor about your results. If your numbers are not in the normal range, ask how to improve them.

Serum Creatinine: Creatinine is a waste product in your blood that comes from muscle activity. It is normally removed from your blood by your kidneys, but when kidney function slows down, the creatinine level rises. Your doctor should use the results of your serum creatinine test to calculate your GFR.

Glomerular Filtration Rate : Your GFR tells how much kidney function you have. It may be estimated from your blood level of creatinine. If your GFR falls below 30 you will need to see a kidney disease specialist . A GFR below 15 indicates that you need to start a treatment for kidney failure. Your kidney disease specialist will speak to you about treatments for kidney failure, such as dialysis or kidney transplant.

Blood Urea Nitrogen : Urea nitrogen is a normal waste product in your blood that comes from the breakdown of protein from the foods you eat and from your body metabolism. It is normally removed from your blood by your kidneys, but when kidney function slows down, the BUN level rises. BUN can also rise if you eat more protein, and it can fall if you eat less protein.

Why Creatinine Tests Are Done

Doctors use creatinine and creatinine clearance tests to check how well your kidneys work. This is called renal function. Testing the rate of creatinine clearance shows the kidneys’ ability to filter the blood. As renal function gets worse, creatinine clearance also goes down. Your doctor may also order a creatinine test if you have symptoms of kidney disease, including:

  • Nausea

  • Changes in how much you pee

  • Swollen feet and ankles

Why Kidney Function Tests Are Performed

Kidney function tests are performed for a variety of reasons, including something as simple as a yearly checkup, or a urinary tract infection is suspected. They may also be performed if an individual is ill and a diagnosis has not been made, as a screening test for a patient planning or recovering from surgery, or as a way to track kidney disease. Urinary tract infections are common after surgery, and some patients experience kidney dysfunction after a procedure, so these tests are frequently performed on patients recovering from surgery.

Kidney function tests are a reliable way of testing the kidneys, but it is important to remember that they can also change dramatically with illness or dehydration. Many individuals can have an acute problem with the kidneys that resolves after receiving fluids or other treatment.

Preventing Poor Kidney Function Or Kidney Damage

There are many things we can do to avoid harm to our kidneys.

  • Never do self-medication. Even when taking medicines, it is best to follow the doses that are prescribed. Taking doses that are too high can cause irreversible damage to the kidneys.
  • Avoid unnecessary exposure to household chemicals. Pesticides, floor cleaners etc. must be used only if necessary.
  • Kidney and urinary tract infections can lead to kidney failure if left untreated. Follow the doctors orders and maintain a healthy lifestyle.
  • Are All Renal Panel Tests The Same

    Kidney function test

    It is common for there to be some variation in the individual components of a renal panel based on the specific laboratory that performs your test. However, some test elements, such as the electrolytes, glucose, calcium, phosphorus, and albumin are found on the most common renal panel tests offered by major laboratories.

    In addition, your doctor can request that other specific measurements be included with your renal panel. You will see a line item for each component when you review your test report, and your doctor can explain the significance of each component and the results in the context of your health situation.

    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.

    What Is A Creatinine Test

    A creatinine test, also called a serum creatinine test, is a way for doctors to measure how well your kidneys are working. Creatinine is a waste product from the normal breakdown of muscle tissue. As your body makes it, it’s filtered through your kidneys and expelled in urine. Your kidneys‘ ability to handle creatinine is called the creatinine clearance rate, and this helps estimate how fast blood is moving through your kidneys, called the glomerular filtration rate .

    Why Do I Need A Gfr Test

    Early stage kidney disease doesnt usually cause symptoms. But you may need a GFR test if you are at higher risk of getting kidney disease. Risk factors include:

    Later stage kidney disease does cause symptoms. So you may need a GFR test if you have any of the following symptoms:

    • Urinating more or less often than usual
    • Loss of appetite

    Who Has A Blood Test Of Kidney Function

    What is BUN and Creatinine – Kidney Function Test

    Routine kidney function is one of the most commonly performed blood tests. It may be done:

    • As part of a general health assessment.
    • If you have suspected low body water content , when the urea level increases.
    • If you have suspected kidney failure. The higher the blood levels of urea and creatinine, the less well the kidneys are working. The level of creatinine is usually used as a marker as to the severity of kidney failure. Creatinine in itself is not harmful but a high level indicates that the kidneys are not working properly. So, many other waste products will not be cleared out of the bloodstream. You normally need treatment with dialysis if the level of creatinine goes higher than a certain value.
    • Before and after starting treatment with certain medicines. Some medicines occasionally cause kidney damage as a side-effect. Therefore, kidney function is often checked before and after starting treatment with certain medicines.

    Nutrition And Low Kidney Function

    Food is what our bodies use for growth, homeostasis, and healing. This is why its important for you to consult with a dietician who is knowledgeable about kidney disease. Youll need to find and maintain a balance between the levels of electrolytes, minerals, and fluid in your body.

    A modified diet for chronic kidney disease may include adjustments to your intake of the following food items:

    What To Do With Gfr 51

    What to do with GFR 51? To understand well about its answer, it is necessary to firstly learn about what GFR is and what GFR 51 mean.

    What is GFR?

    GFR is the abbreviation of Glomerular Filtration Rate which is the volume of fluid filtered by the kidneys within a certain period of time, so GFR is aways measured to know how well the kidney function.

    What does GFR 51 mean?

    Normally, GFR ranges from 90-120 mL/min/1.73m2 and also there is no evidence of kidney damages. GFR 51 is clearly lower than the normal range, which always indicate kidney problem. Kidneys help us discharge waste products produced in our body through filtering blood. Low GFR mean kidneys can not filter blood successfully and this may cause buildup of wastes in the blood. Under such a condition, a series of measures are needed to improve kidney condition.

    What to do with GFR 51?

    For people with GFR 51, they generally need to improve their kidney condition through the following several aspects:

    1. Well-planed diet

    Diet is an essential part of the treatment for kidney disease. There is no such a food list that is suitable for all the patients due to the difference of illness condition, but kidney disease patients usually need to reduce protein intake, result salt intake, result fluid intake if there is swelling as well as reduce potassium intake and phosphorus intake if lab tests show high levels of potassium and phosphorus level in blood.

    2. Tight control of blood pressure and blood sugar

    About Normal Ranges And Interpreting The Numbers

    When you look at a printout of your lab results, youll find the normal ranges for each blood test next to your personal results. For example, if your routine blood work includes a test for calcium in the blood, your lab may list the normal range for calcium as 8.3 to 9.9 milligrams per deciliter . If your result is a 9.1 mg/dL, right in the middle, you can feel confident that your calcium level is normal.

    But what if a blood test result is at the very low or high end of normal, or even slightly outside the normal range? Is that a red flag? Dont jump to conclusions, warns Dr. Salamon. Blood test results can vary a little bit, depending on the lab. And many people are consistently on one side or the other of the normal range, and for them, thats healthy, says Dr. Salamon.

    Take, for example, a routine measure of blood urea nitrogen , a waste product created as your body breaks down the protein in your diet. Excess urea is removed from the blood by the kidneys, so high levels of BUN in the blood can indicate that kidney function is declining. So, what does it mean if your BUN level is at the very high end of the normal range? If I see that its borderline high, I might ignore it, says Dr. Salamon. Its common for BUN to go up if you dont drink enough, and that can happen when someone is fasting before having blood drawn.

    Minor fluctuations in test results may also reflect

    • recent infections
    • age
    • inaccurate lab procedures.
