title: [Proceedings: Evaluation of the plasma-phenolred test as a simple kidney function test].
abstract: The phenolsulphthalein 60/60 plasma test (PSP 60/60) was evaluated in 30 control subjects (mean value 51 micrograms/100 ml +/- 49 micrograms/100 ml) and 60 patients with chronic renal disease with varying degrees of renal insufficiency. PSP 60/60 proved to be superior to determination of serum creatinine and urea nitrogen. PSP 60/60 correlated well with endogenous creatinine clearance and 131I-iodohippurate clearance in over 80% of cases. Of various exogenous and endogenous factors interfering with the test, drugs influencing renal excretory mechanisms are most important. Due to its technical simplicity, PSP 60/60 is a useful screening test for evaluation of renal function, especially as an office procedure.
