[Determination of renal clearance with only a single access for injection and blood extraction]. / Bestimmung der renalen Clearance mit nur einem Zugang für Injektion und Blutentnahme.

ABSTRACT

An injection technique was developed to administer radioactivity to children and adults and to withdraw plasma samples through the same venous line. The error in clearance estimation due to "contamination" was smaller than that caused by the timing of blood sampling or the type of algorithm used for clearance calculation.
