The Creatinine Test measures the level of creatinine, a waste product produced by muscle metabolism, in your blood or urine. Creatinine is usually filtered and removed by the kidneys, so elevated blood creatinine indicates impaired kidney function or kidney disease. This test helps diagnose and monitor kidney health in conditions like diabetes, hypertension, or kidney injury. A blood sample is commonly used, occasionally alongside a 24-hour urine collection. It’s often combined with other tests, such as blood urea nitrogen (BUN), to assess kidney function more accurately. Patients may need to fast or avoid meat before testing and should inform their doctor of any medications they are taking. This test is crucial for early detection of kidney problems and for guiding treatment and medication adjustments. Redcliffe Labs offers convenient home sample collection with timely, reliable reports for kidney health monitoring.
