title: An examination of the xenon clearance method.
abstract: A definition of cortical and juxta-medullary regions is suggested based on a grouping of nephrons of common flow characteristics. A possible error is suggested in the xenon clearance method of measuring the regional flows. Experiments to test the source of error and its magnitude are described. It is concluded that while the error is present its effect on conventional component analysis is small.
