DETERMINATIONS OF THE MAG(3) CLEARANCE AC CORDING TO THE WHOLE-BODY PRINCIPLE AND TO RELATED METHODS

To answer the question Cor the most effective use of all usually avail able information, the MAG(3) clearance was determined by different met hods: firstly in an optimated whole-body technique for reference, furt her for comparison by means of a camera background-curve and a dedicat ed evaluating procedure, and in addition according to the compartmenta l principle (Sapirstein), by the latter method also simultaneously tog ether with the hippurate clearance. Two simplified methods were applie d as well, a non-invasive one and a single-sample method. The results revealed the relatively unpretentious camera technique to be nearly eq uivalent to more expensive procedures, but qualitatively superior to t hese methods, which are unnecessarily oversimplified.
