It’s important to know the basics of creatinine clearance. This test is used to measure how well your kidneys are functioning, and it can help diagnose kidney disease or determine if you’re at risk for developing one. But what should a nurse do before starting this test?
We’ll go over that here! Creatinine is a waste product of creatine and creatinine clearance measures the level in your blood, which indicates kidney function. There are different types of tests that can be used to measure this: Serum creatinine (blood), 24-hour urine collection, or timed collections for up to 14 days. Each has its advantages and disadvantages depending on the person’s condition.
A nurse may start by reviewing the lab orders with you so they know what type of specimen will need to be collected; then we’ll go over how long it needs to wait from when it was taken before being sent off for testing.
Finally, we’ll discuss how often you should collect them.
