a marked decrease in the elimination of the phenolsulphonephthalein occurs synchronously , as a rule , with the onset of the symptoms of intoxication ( vomiting ) , and therefore the phenolsulphonephthalein test would seem to be a better indicator of the ability of the kidney to eliminate the toxic substance responsible for the symptoms of renal insufficiency than are either the anatomic changes or the elimination of total nitrogen or of chlorides .
