About This Test
About This Test
Who should be tested?
1 in 7, or 37 million Americans, are estimated to have chronic kidney disease (CKD).* But 40% of those with severely reduced kidney function are unaware that they are at risk.* The sooner you know more about your kidney health, the sooner you can take steps with your provider to protect them. Because early CKD has no signs or symptoms, getting tested regularly can help prevent or manage CKD and lower the risk of kidney failure. Testing can start conversations with your healthcare provider about managing your kidney health. In particular, people with risk factors for kidney disease should stay on top of their kidney testing.
You should consider testing if you have the following risk factors for CKD**
You have diabetes
You have high blood pressure (hypertension)
You have heart disease and/or heart failure
You are obese
You are over the age of 60
You have a family history of CKD or kidney failure
You have a personal history of acute kidney injury (AKI)
You smoke and/or use of tobacco products

Symptoms
Your kidneys are responsible for filtering your blood and removing waste products through your urine. If the kidneys become damaged over time, this is called chronic kidney disease, or CKD.
During the early stages of CKD, you may not experience any symptoms at all. The only way to find out for sure if you have CKD is through testing. The earlier treatment starts, the better. In the later stages of CKD, symptoms can include:
Swelling in the legs, ankles, feet, and hands
Pain in your lower back
Feeling weak and tired for long periods of time
Urinating more or less than usual or producing less urine
Itchy or dry skin
Muscle cramps or seizures
This testing option is not an alternative to a consultation with a healthcare provider, who you should talk to about any concerns or symptoms. They may recommend additional tests to check the health of your kidneys, such as a urine test.
When to test
You should collect your sample Monday-Friday and return the sample on the same day. Consuming large amounts of protein, including red meat, protein shakes, and supplements, before collecting your sample may impact your creatinine result by temporarily elevating it. . .
What's measured
Urea
Urea is waste produced by the liver when it breaks down protein. It is passed from the liver to the kidneys through the bloodstream. Once filtered through the kidneys, urea leaves the body as urine.
Creatinine
Creatinine is another waste product formed when muscles contract. Creatinine travels through the bloodstream from muscles to the kidneys, where it is filtered out and leaves the body in urine. If you have kidney disease, the kidneys can have trouble removing creatinine from your blood, and the level of creatinine in your blood can increase.
eGFR (Estimated Glomerular Filtration Rate)
Your kidneys filter all the blood in your body every 30 minutes for your entire life. They remove wastes, toxins, and excess fluid from your blood. The estimated glomerular filtration rate (eGFR) is an estimate of how well your kidneys remove waste products from the blood. It is calculated using your creatinine level, age, and sex.
