Description
Creatinine Clearance
Sample Type:Serum+Urine
Sample Required:
Blood sample
Test Time:
Results typically available within a few days.
What is the test?
This test measures the level of creatinine in the blood. Creatinine is a waste product produced by muscle metabolism and is filtered by the kidneys.
Test Procedure:
Blood is drawn, and the level of creatinine is measured in the laboratory.
When to take the test:
Routinely for kidney function assessment or in cases of suspected kidney disease or impaired kidney function.
Who should take the test:
Individuals with kidney disease, hypertension, diabetes, or other conditions affecting kidney function might undergo this test for monitoring.
Precautions for exceptional cases (pregnancy, etc.):
Pregnancy can affect creatinine levels; adjustments might be needed in interpretation.
Frequently Asked Questions (FAQs) for Creatinine Test:
Q1: What do elevated creatinine levels indicate?
A: Elevated creatinine levels can indicate reduced kidney function or kidney disease.
Q2: Can creatinine levels fluctuate?
A: Yes, creatinine levels might vary based on factors like muscle mass, diet, and hydration status.
Q3: Are there medications that can affect creatinine levels?
A: Yes, certain medications, especially those affecting kidney function, can impact creatinine levels.
Q4: How is creatinine clearance different from creatinine levels?
A: Creatinine clearance involves collecting urine to measure the rate at which creatinine is cleared from the blood by the kidneys, providing a more direct assessment of kidney function.
Q5: Is a single creatinine test sufficient to diagnose kidney disease?
A: Additional tests and evaluation, such as eGFR and urine tests, are often needed for a comprehensive assessment of kidney function and disease.
