Can creatinine tests detect early-stage kidney disease?

Yes, elevated creatinine levels can be an early indicator of kidney dysfunction or damage. However, a single elevated creatinine test may not always confirm kidney disease. Doctors often combine creatinine testing with other measures, such as the glomerular filtration rate (GFR), to detect early-stage kidney disease. Early diagnosis is critical for preventing further kidney damage and managing conditions like chronic kidney disease (CKD). Regular testing and monitoring help catch kidney problems early, allowing for timely intervention.
