renal clearance

Renal clearance is a measure of how effectively the kidneys remove a substance from the blood and excrete it into urine. It reflects the volume of blood cleared of that substance per minute. For example, if a substance has high renal clearance, the kidneys are very efficient at removing it. This helps doctors assess kidney function and determine how well the kidneys are working. Renal clearance depends on factors like blood flow, filtration at the kidney's filters, and how the substance is processed or reabsorbed in the kidneys.
