    • Individuals with conditions that affect muscle mass or muscle breakdown, as creatinine levels are influenced by muscle activity.

    Commonly used for diagnosis of

    This test is commonly used to diagnose and monitor a variety of kidney-related conditions, including:

    • Chronic Kidney Disease (CKD): Early detection of impaired kidney function, allowing for timely intervention and management to slow disease progression.
    • Acute Kidney Injury (AKI): Rapid assessment of sudden kidney damage caused by factors such as severe infection, dehydration, or certain medications.
    • Diabetes and Hypertension: Monitoring kidney health in individuals with these conditions, as they are leading causes of kidney disease.
    • Glomerulonephritis and Nephrotic Syndrome: Evaluating inflammation and damage to the kidney's filtering units.
    • Urinary Tract Obstruction: Assessing kidney function when there's a blockage in the urine flow.
    • Medication Monitoring: Tracking kidney function in patients taking drugs that can be nephrotoxic (harmful to kidneys).
    • Pre-Surgical Assessment: Ensuring healthy kidney function before administering anesthesia or undergoing procedures that might affect the kidneys.

    Caution

    Important caution

    It is crucial to discuss your test results with a healthcare provider. Abnormal creatinine or eGFR levels can indicate a range of underlying conditions, and your doctor can help interpret the results in the context of your overall health, medical history, and other test findings. Do not attempt to self-diagnose or self-treat based solely on these results.
