Although phenol red, introduced by Rowntree and Geraghty (6) in 1912, has been widely used in man as an empirical renal function test, the excretion of this substance relative to its concentration in the plasma has been examined in only one instance. MacKay (1930) injected one gram intravenously and calculated the Addis excretory ratio in three successive periods when the plasma level was 5.80,...

The study of a variety of experimental renal lesions in the dog demonstrates that the phenolsulphonephthalein test of Rowntree and Geraghty is one of the most satisfactory and at the same time most delicate methods of estimating the functional activity of the kidney. The elimination of the test dye is decreased in so-called spontaneous nephritis and in experimental nephritis due to potassium ch...
