This idea of the fundamental importance of the patency of the organ underlies the many attempts to discover means of assaying the functional capacity of the affected organ. The kidney, on whose integrity an individual's welfare depends to a large extent, has been the object of the greatest number of functional tests. The tests most in vogue in clinical medicine fall into several groups depending on the particular task which each purports to present to the kidney. One of the most commonly employed tests is concerned with the ability of the kidney to rid the body of a foreign body, such as the dye phenolsulphonephthalein.1 Others attempt to place the kidney under an increased strain in performing its excretory function, by increasing very greatly the amount of sodium SN - 0730-188X M3 - doi: 10.1001/archinte.1923.00110130119011 UR - http://dx.doi.org/10.1001/archinte.1923.00110130119011 ER -
