Examples of fractional contributions on a typical curve for the kidney for a (fc0-24) the extrapolated portion of the curve from time = 0 to the measurement at day 1, b (fc168-∞) the portion of the curve after the day 7 measurement (to infinity), c (fc0-24 + 168-∞) the sum of fc0-24 and fc168-∞, d (fc96-∞) the portion of the curve after the day 4 measurement (to infinity), e (fc0-24 + 96-∞) the sum of fc0-24 and fc96-∞, and (fc0-8) the fractional contribution of the first 8 h
