[Determinations of MAG3 clearance according to the whole-body principle and to related methods].
To answer the question for the most effective use of all usually available information, the MAG3 clearance was determined by different methods: firstly in an optimated whole-body technique for reference, further for comparison by means of a camera background-curve and a dedicated evaluating procedure, and in addition according to the compartmental principle (Sapirstein), by the latter method also simultaneously together with the hippurate clearance. Two simplified methods were applied as well, a non-invasive one and a single-sample method. The results revealed the relatively unpretentious camera technique to be nearly equivalent to more expensive procedures, but qualitatively superior to those methods, which are unnecessarily oversimplified.
