Important quantitative tests of renal function include those of glomerular filtration rate, renal clearance, and renal blood flow. Tests are also made to estimate maximal tubular activity, tubular mass, and tubular function. Radiological and other imaging methods are useful noninvasive diagnostic techniques, and renal biopsy is valuable in detecting pathological changes that affect the kidneys. In both clinical and experimental studies one of the most fundamental measures of renal function is that of the glomerular filtration rate (GFR). The GFR is calculated by measuring the specific clearance from the body of a substance believed to be excreted solely by glomerular ...(100 of 14829 words)
