Creatinine
CR
Description
"Creatinine" test measures the amount of this waste product in your blood to evaluate kidney filtration and metabolic function. Changes in creatinine levels often show up before kidney disease symptoms fully develop. Elevated readings may indicate reduced kidney performance or blockage, while lower levels can be tied to muscle loss or malnutrition. This test offers critical insight into kidney efficiency. Tracking creatinine over time supports early intervention and helps shape long-term care plans for renal health.

Key Reasons For Testing
Kidney Function: Identifies kidney impairment or dysfunction by measuring elevated creatinine levels.
Kidney Disorders: Monitors chronic kidney disease, acute kidney injury, or progression of renal issues.
Glomerular Filtration Rate (GFR): Estimates kidney function to assess overall renal health.
Dehydration Detection: Highlights elevated creatinine levels caused by dehydration or fluid imbalance.
Treatment Monitoring: Tracks creatinine changes to evaluate therapy outcomes or effectiveness.
Drug Toxicity: Detects potential kidney damage caused by medications, guiding safe usage.

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.
