Easy: Calculate Creatinine Clearance from GFR (eGFR)

Estimating kidney function is crucial in clinical practice. Glomerular filtration rate (GFR) is a primary indicator of renal function. Creatinine clearance, a related measurement, assesses the rate at which creatinine, a waste product, is filtered from the blood by the kidneys. While GFR is often directly measured or estimated using equations incorporating serum creatinine, age, sex, and race, it’s important to understand the relationship between GFR and creatinine clearance. Typically, these values are similar, but discrepancies can arise due to tubular secretion of creatinine, which can lead to creatinine clearance overestimating GFR. Adjustments may be necessary when comparing or interpreting these values.

The assessment of kidney function through GFR and creatinine clearance plays a vital role in the diagnosis and management of kidney disease, medication dosing, and monitoring overall health. Historically, creatinine clearance was a widely used marker of kidney function, often measured directly from a 24-hour urine collection.
