Creatinine Clearance
CRCL
Description
"Creatinine Clearance" test evaluates how efficiently your kidneys clear creatinine from your bloodstream by combining blood and 24-hour urine measurements. It’s used to assess kidney performance and track conditions like diabetes or high blood pressure. Abnormal clearance rates may signal impaired filtration, dehydration, or early-stage kidney disease. Doctors rely on this test to uncover subtle changes in kidney health and refine care strategies. Regular testing provides a detailed picture of kidney function over time.

Results That Differ From The Norm (Direct and Indirect Causes)
Increased levels may indicate:
Pregnancy
Decreased levels may indicate:
Dehydration
Glomerular disease (damage to the kidney's filtering units)
Heart failure (inability of the heart to pump blood effectively)
Kidney damage
Kidney failure
Lower urinary tract obstruction (blockage in the urinary tract)
Renal artery stenosis (narrowing of the renal arteries)
Key Reasons For Testing
Kidney Function: Measures how effectively the kidneys filter creatinine to assess overall function.
GFR Estimation: Provides a key indicator of kidney health for diagnosing and staging disease.
Chronic Kidney Disease (CKD): Monitors CKD progression and evaluates treatment effectiveness.
Acute Kidney Injury (AKI): Detects early signs of AKI to guide timely interventions.
Drug Dosage Adjustment: Helps tailor dosages for medications cleared through the kidneys.
Renal Blood Flow: Offers insights into kidney perfusion and hemodynamics.

Important Note
Any medical procedure yielding results outside the norm may be directly or indirectly linked to the conditions outlined on this page. Various factors, including genetics, medication and supplement usage, recent illnesses, pregnancy, pre-test eating, smoking, and stress, can impact the test's outcome. Additionally, factors like false positives, false negatives, inaccurate analyses, and others can influence results.
Reference ranges, which help healthcare professionals interpret medical tests, may vary depending on age, gender, and other factors. They may also differ between laboratories due to variations in instruments and methods used. Optimal ranges are designed for preventive purposes, aiming to identify trends and potential risks early, while normal ranges reflect conventional laboratory values indicating no current disease or pathology. Your healthcare practitioner may have specific reasons for testing that deviate from the usual or may interpret results differently based on individual circumstances. Proper interpretation typically involves considering clinical findings and other diagnostic tests. Hence, it is crucial to provide your healthcare professionals with a comprehensive medical history, consult with them for result interpretation, and follow their guidance for potential re-testing or additional diagnostics.
