AN EVALUATION OF SOME COMMERCIAL TEST PAPERS AND TABLETS FOR THE DETERMINATION OF GLUCOSE IN URINE.
The commercial test papers, Tes-Tape, Clinistix, Uristix and Combistix, and the tablet preparation, Clinitest, were evaluated as indicators of glucose in urine by means of a quantitative automated glucose oxidase procedure for glucose determination. The semiquantitative Tes-Tape yielded very low values on urine specimens when compared with the quantitative method. More reliable results could be obtained with this product if the urine specimens were first treated with a mixed bed resin to remove inhibitors of the glucose oxidase peroxidase system. The qualitative test papers, Clinistix, Uristix and Combistix, yielded responses in closer agreement with the automated data, the best performance being obtained with Clinistix. The semiquantitative Clinitest tablets generally yielded more accurate results on a direct urine test than did Tes-Tape, although the Clinitest tablet is designed to measure total reducing substances rather than glucose alone.
