Get tested and diagnosed

Learn about the urine test, called a UACR, eGFR kidney function test, what your test results mean, and the importance of catching CKD early so you can do more to protect your kidneys.

UACR urine test

The earliest way to find out if you are at risk for chronic kidney disease (CKD) is by taking a UACR (urine albumin-to-creatinine ratio) test once a year. A UACR test can detect how much small protein, called albumin, is in your urine. This is the earliest indicator of kidney damage. A damaged kidney can’t filter as well as it should and lets some protein pass into the urine. A healthy kidney doesn’t let any protein pass into the urine.

 

A UACR test is usually the earliest indicator of kidney damage, but isn’t always part of a routine health screening and is different from usual urinalysis tests that are commonly used at doctor’s appointments, so be sure to ask your healthcare provider specifically for a UACR test.

A normal UACR result may be 30 mg or less, and an abnormal result may be above 30 mg

Kidney function test (eGFR)

An eGFR (estimated glomerular filtration rate) test is a blood test that measures how well your kidneys filter waste from your blood and how well your kidneys are functioning. Your eGFR is a number based on how much creatinine is in your blood. Creatinine is a waste product and healthy kidneys remove it from your blood. As kidney disease gets worse, less creatinine is removed by the kidneys, leading to higher levels in the blood.

 

An eGFR test is used to measure how well kidneys are functioning, but it is not as accurate as a UACR test to show if you are beginning to develop CKD. This is because in early stages of CKD, you can still have close to normal kidney function even if your kidneys have mild damage. Once your kidney function begins to decline, as measured by an eGFR test, the damage cannot be reversed, but there are steps you can take to slow the progression of CKD.

A normal eGFR result may be 60 or higher, and an abnormal result may be less than 60

Importance of chronic kidney disease testing and prevention

When it comes to your kidney health, it’s important to talk to your healthcare provider about getting screened for chronic kidney disease with a urine test, called a UACR, once a year. The sooner you catch CKD, the more you can do to slow its progression and prevent future kidney damage.
