Kidney Health Test

$ 99.0

Your kidneys may be small, but this kidney function test provides a big picture of your health.

Your kidneys work hard, keeping your body healthy and removing waste products from your blood. Without the kidneys, these toxins would build up in the body and cause damage. People with Chronic Kidney Disease (CKD) may not feel ill or notice any symptoms until CKD is advanced. This blood test checks for the level of creatinine, a waste product produced by muscles, to see how well the kidneys work. This kidney test includes markers that measure overall kidney function indicating possible kidney disease or damage.

What's Tested
  • Creatinine 

    A muscle-produced waste product filtered out by the kidneys.

  • Albumin (Urine)

    The main protein that circulates in the blood, which provides tissue nourishment, carries substances (such as hormones and drugs) in the blood and helps keep fluids within the blood vessels.

  • Albumin-Creatinine Ratio

    A calculation that divides the amount of albumin measured in the urine by the urine creatinine level to correct for urine concentration.

  • Estimated Glomerular Filtration Rate (eGFR)

    A calculation (factored from your serum creatinine level, age, and gender) used to determine your level of kidney function; the higher your eGFR number, the better your kidneys are working; low results may be a sign of kidney disease.

  • A normal estimated glomerular filtration rate (eGFR) range may vary depending on an individual’s age and sex. An eGFR number greater than 90 is usually considered within the normal range, while 60-89 may indicate early-stage kidney disease. Numbers lower than 60 may indicate kidney disease or failure. However, in senior adults (i.e., those aged 60 or older), lower eGFR numbers, such as 85, are more common.3  

  • According to the National Kidney Foundation, the top signs of kidney disease include4:

    • Fatigue
    • Difficulty sleeping
    • Dry, itchy skin
    • Blood in urine
    • Change in urination
    • Puffiness around the eyes
    • Swelling in the feet and ankles
    • Decreased appetite
    • Muscle cramps


    If you have symptoms consistent with kidney disease, be sure to talk to your primary healthcare provider to see if a kidney health test is right for you.    

  • CKD often begins without causing any obvious symptoms. If detected and treated early, you can help slow or even stop CKD from getting worse.


    People with certain risk factors have a higher risk of developing CKD and should consider testing their kidney health with our kidney function test.2


    According to the National Kidney Foundation, the most common CKD risk factors are:

    • Diabetes
    • High blood pressure
    • Heart disease and/or heart failure
    • Obesity (having a body mass index or BMI of 30 or more)
    • Over the age of 60
    • Family history of CKD or kidney failure
    • Personal history of acute kidney injury (AKI)
    • Smoking and/or use of tobacco products
  • Your testing will be performed in a CLIA-certified clinical laboratory. Labcorp provides leading-edge medical laboratory tests and services through a national network of primary clinical laboratories and specialty testing laboratories. Our labs perform regular quality assurance testing to ensure our results are accurate.

  • Your results will be provided to you through our secure online portal to view or print. Results are also provided to PWNHealth, which provides professional healthcare provider services for OnDemand tests. If you are accessing your results through your Labcorp Patient account, all users linked to the account will have access to all OnDemand test results. Results may also be provided to a local, state, or federal health authority, but only when legally required. For example, many states require the testing laboratory and healthcare provider to report test results for certain communicable diseases, such as sexually transmitted diseases or COVID-19, to local or state health departments.
