Description
Urine, NA, Fasting or Non Fasting: As suggested by doctor
Sample Required:
For the creatinine clearance test using a 24-hour urine collection, you will need a clean, dry container to collect all urine produced over a 24-hour period.
Test Time:
The creatinine clearance test requires a 24-hour urine collection, and the results are typically available within a day or two after completing the collection.
Test Normal Range:
The normal range for creatinine clearance can vary depending on factors such as age, sex, and muscle mass. Your healthcare provider will provide specific reference values based on your individual characteristics.
What is the Test?
The creatinine clearance test measures how efficiently your kidneys filter waste products, particularly creatinine, from your blood. Creatinine is a waste product produced by muscle metabolism and is normally excreted by the kidneys. This test helps assess kidney function.
Test Procedure:
The creatinine clearance test is conducted over a 24-hour period and involves the following steps:
Start of Collection: Begin with an empty bladder and note the exact start time. This is typically in the morning.
Urine Collection: Collect all urine produced over the next 24 hours in the provided container. Ensure that each voided urine is collected in the container.
Storage: Keep the container in a cool place or refrigerator during the collection period.
End of Collection: Finish the collection at the same time the next day, even if you need to empty your bladder before that time.
Return to Laboratory: Return the urine container to the laboratory or healthcare provider for analysis.
When to Take the Test:
The creatinine clearance test is commonly used to evaluate kidney function, especially in individuals with known or suspected kidney problems, high blood pressure, or diabetes. It can also be a part of routine health assessments.
Who Should Take This Test:
Individuals with kidney disease or those at risk for kidney issues. People with high blood pressure or diabetes. Those taking medications that may affect kidney function. Patients undergoing treatments that can impact kidney health, such as chemotherapy.
Precautions for Exceptional Cases (Pregnancy, etc.):
The creatinine clearance test is generally safe during pregnancy, but reference values may differ for pregnant individuals. Always inform your healthcare provider if you are pregnant or breastfeeding, as they may consider this when interpreting results.
