The formula includes some or all of the following: Age Blood creatinine measurement Ethnicity Sex Height Weight The creatinine clearance test , which involves a hour urine collection, can also provide an estimate of kidney function.
How to Prepare for the Test. Tell your doctor if you are pregnant or think you might be. GFR is affected by pregnancy. How the Test will Feel.
Why the Test is Performed. CKD risk factors include:. Later stage CKD does cause symptoms. So you may need an eGFR test if you have any of the following symptoms:. There is very little risk to having a blood test. You may have slight pain or bruising at the spot where the needle was put in, but most symptoms go away quickly. You may need to fast not eat or drink or avoid certain foods for several hours before the test.
Your health care provider will let you know if there are any special instructions to follow. A health care professional will take a blood sample from a vein in your arm, using a small needle. This information does not replace the advice of a doctor.
