Did you know an estimated 37 million Americans have kidney disease—and a little less than half don't even know it? Kidney disease is a leading cause of death in the United States, with diabetes and high blood pressure leading to 3 out of 4 new cases of chronic kidney disease (CKD). Many of these cases go undiagnosed until kidney disease is advanced because the signs can be so subtle.

While being tested in a laboratory through your doctor is the gold standard, a lack of access to health care and insurance coverage can make testing at the hospital or through a traditional doctor’s office difficult and expensive for some people. The number of companies offering at-home lab testing is on the rise, reducing red tape and the cost of testing. We put together a list of some of the best at-home kidney function tests to use, so you can get speedy, confidential results in your home and take the appropriate next steps if required.

Many of the tests used by Walk-In-Lab’s home kidney testing kits use either a blood or urine sample collected at home. Your collection kit will include the supplies you need and instructions for collection. Blood spot tests require only a fingerstick with a lancet. Urine samples will be placed in a supplied collection device.

If your kit requires a blood draw, you have a few options: you can use the lab finder tool on Walk-In-Lab’s website to find a lab near you, or you can even call to schedule a visit from a mobile phlebotomist at your home. If you need to visit a lab or schedule a mobile lab visit for a blood draw, the lab will submit your sample. All other samples can be mailed back to Walk-In-Lab with a prepaid shipping envelope.

Testing options range from a $22 urine dipstick to detect the presence of protein in the urine to the Kidney #3 Extreme Blood and Urine Test Panel, which costs $308. The labs that process your results are fully accredited and are the same labs that process tests for hospitals. Results are available in 24 to 48 hours on a secure, HIPAA-compliant server.

While the Kidney #3 Extreme Blood and Urine Test Panel costs $308, it also includes a complete blood count (CBC), comprehensive blood panel (CMP), urinalysis with microscopic examination plus parathyroid hormone, vitamin D testing, protein, and creatinine testing, and more. This test includes a variety of sample types, so be sure to read the collection instructions included in your kit carefully.

While Walk-In-Lab does not accept insurance, Medicare, or Medicaid, you can request a receipt to submit to your insurance company on your own for reimbursement.

Best Tool for Doctors : 

Key Specs
  • Pricing: Depends on the healthcare provider
  • Test results: Within minutes (results automatically sent to physician)
  • Sample type: Urine sample
Why We Chose It’s CKD Early Detection Test provides testing from the comfort of your own home and sends clinical-grade results automatically and securely to your healthcare provider. 

Pros & Cons
  • Simple for users

  • Cost-saving for health systems as a tool to prevent costly disease progression

  • Opportunity to catch kidney disease early and halt progression

  • Only available through your doctor


High blood pressure is a risk factor for kidney disease, and an early indication that hypertension is leading to kidney disease is the presence of proteins in your urine. The CKD Early Detection Service uses an at-home urine test to screen the urine of high-risk people for the presence of these proteins.

The Geisinger Health System in rural Pennsylvania conducted a trial funded by the National Kidney Foundation to evaluate the effectiveness of a home testing kit combined with a smartphone app to screen for protein in the urine of patients with high blood pressure, but not kidney disease. The study found that the use of an at-home urine test combined with a smartphone app and telephone contact improved urine protein screening rates by about 11% when compared with mailed reminders alone.

While you can’t buy this kit directly from the company as a patient, your doctor can request it for you to make screening easier to do at home. The test has earned FDA approval as a home test for chronic kidney disease, but the company has not offered any information on insurance coverage.

The At-Home Kidney Test from combines at-home urine testing with data sharing over a smartphone app. Here’s how the home test works: first you download a smartphone application, then you are mailed a dipstick, a specially designed collection cup, and a color-coded board to help analyze the samples in various home lighting environments. When collecting a sample, you simply open the app and follow the on-screen instructions, collecting urine, and placing it in the provided container.

Next, you place the dipstick in the collection cup, then place the dipstick on the color board and scan both the dipstick and the color board with your phone, using the app. Results are sent to a HIPAA-compliant portal to be analyzed. You receive confirmation that testing is done and are alerted to an abnormal test. Your doctor is notified of any abnormal results and follow-up testing needs.

Best for Price, Convenience : Labcorp OnDemand

Key Specs
  • Pricing: $89
  • Test results: Depends on the test
  • Sample type: Blood and urine sample
Why We Chose It

Labcorp OnDemand's Kidney Health Test Package measures overall kidney function and indicates possible kidney damage with an easy-to-use kit that offers quick, online access to results.

Pros & Cons
  • Online support and results on HIPAA-compliant portal

  • Easy access to physicians to review orders and test results

  • Complaints in online reviews about customer services

  • Limited testing options


Labcorp OnDemand’s Kidney Health Test Package allows you to get kidney function test results at home. The kidney test includes all the measurements that will give a snapshot of your kidney’s overall health—creatinine, estimated glomerular filtration rates, albumin, and the albumin-creatinine ratio—for the price of one or two tests from competitors.

Other tests can give you much more detailed information about your kidneys, but this $89 test kit will provide you with enough information to show any red flags or concerns. You may also find cheaper tests, but they may not include as many measurements within your lab results.

Labcorp requires a doctor's order for all tests, but the company contracts with physicians to provide the order for you. You don’t make appointments with these physicians, but they are available to review your orders and results, and the cost of these services is included in your testing kit price. Your test results will be reviewed by physicians with this service, and you will be contacted directly by phone if your results are urgent.

Urine tests can be mailed, but blood draws must be collected in one of Labcorp’s many 36 primary lab locations across the U.S.—the labs are certified and perform testing for hospitals and clinics as well.

Labcorp doesn’t bill insurance, Medicare, or Medicaid, but you can use Health Savings Accounts (HSA) and Flexible Savings Accounts (FSA) to purchase these kits.

Labcorp also offers the more basic albumin-creatinine ratio test alone for $69. This test uses just a urine sample to detect proteins in your urine.

We did find complaints in online reviews about Labcorp’s lack of responsiveness to customer service issues. The company offers details about its different services online, as well as a help section and a blog, but online support is not available.


Blood glucose self-testing equipment and supplies are covered for all people with Medicare Part B who have kidney disease. This includes those who use insulin and those who do not use insulin.

Frequently Asked Questions

What Is Kidney Disease?

The kidneys filter all the blood in your body every 30 minutes, and kidney disease impacts the ability of your body to filter out excess fluids. Kidney failure happens when these filters don't do their job and fluids and other substances—electrolytes and minerals like potassium and other waste products—build up to dangerous levels in the body. An imbalance in fluids can cause swelling, blood pressure problems, irregular heart rhythms, confusion, and more.

What Are the Types And Causes of Kidney Disease?

Kidney disease occurs for a number of reasons. You may have a genetic or autoimmune disease that compromises your kidney function, or your kidney function could be impaired by having diabetes (high blood sugar), hypertension (high blood pressure), or other diseases like cancer.

What Is the Most Accurate Test for Kidney Function?

Comparing testing for kidney disease is difficult because there are many different methods of collecting and analyzing samples that test kidney function. The most basic criterion for diagnosing kidney disease is a decreased glomerular filtration rate (GFR) value. Glomeruli are tiny filters in the kidneys, and GFR is a measurement that can tell you how well these filters are working.

Is Kidney Disease the Same as a Kidney Infection?

Kidney disease is not the same as a kidney infection. Kidney disease happens when you have a genetic or congenital issue—one you were born with—that causes damage to your kidneys, or when you acquire a disease or your lifestyle choices limit your kidney function. A kidney infection occurs when bacteria, most commonly Escherichia coli, travels from the urethra up through the bladder and ureter into one or both of your kidneys. You can also have a kidney injury—often caused by sudden illness or certain medications—that can resolve in time with little permanent damage.

How Much Do At-Home Kidney Tests Cost?

At-home kidney tests range in cost from about $20 to several hundred dollars. More affordable tests typically have limited results and use a fingerstick or urine sample. The renal system is complicated, so the more accurate tests require larger blood samples, and you may have to supplement a urine sample with a trip to a lab. These tests are usually more expensive, but you can still have them done without seeing your doctor and still have your tests interpreted by a clinician and receive comprehensive information about your kidney function.


The testing kits in this list were evaluated based on the tests included in the package, how samples were collected, what online and phone support was offered, ease of ordering and testing, support and guidance on collecting samples, and cost.

A Word From Verywell

At-home kidney disease tests are considered unreliable by medical professionals. We recommend you consult a doctor for interpretation of test results, confirmation of results, and advice regarding the best ways to manage kidney disease.
