The 24-hour urine collection is the most commonly performed interval. Urine is collected for a fixed period ranging from 6, 12, to 24 hours. As in extrinsic clearance tests, the plasma levels of creatinine or urea are determined. Very little creatinine is secreted by the tubular cells therefore, the concentration of creatinine in urine is an excellent assessment of the tubular excretion function and the GFR. Creatinine is a waste product of muscle metabolism and is produced at a constant rate and proportional to muscle mass. Because approximately 40% of urea is reabsorbed into the tubules, the urea clearance test does not provide a full clearance assessment. The urea clearance test was one of the first clearance tests performed. Intrinsic clearance tests measure chemicals that are intrinsic to the body, such as creatinine and urea. After the time interval, which may be 6, 12, or 24 hours, the urine and plasma are analyzed for the chemical concentration. All urine is collected during the clearance procedure and the volume measured. After the chemical is injected, the plasma concentration is measured. The chemical is injected into the patient intravenously. These chemicals include inulin and p-aminohippurate, among others. Measurements of chemicals that are foreign to the body and completely cleared are known as extrinsic clearance tests. The clearance tests differ from one another by the chemical to be cleared by the kidney and analyzed. This is the rate at which chemicals are filtered or “cleared” from the kidney. In this manner, the glomerular filtration rate (GFR) can be determined. All of them measure three parameters: the plasma (or serum) concentration of the chemical to be cleared, the urine concentration of that same chemical, and the time interval of the clearance procedure. There are many variations on the clearance test. By measuring the concentration per unit of time in urine of a chemical that will be removed or “cleared” by the kidney tubules, the physiologic function of the tubules can be determined. The kidney’s main function is to excrete waste products while reabsorbing water and dissolved chemicals from the ultrafiltrate. This test provides information on the glomerular and tubular function of the kidneys. One of the most common renal function tests is the clearance test.
