Benedict's test for dextrose in the urine can be simplified for practical bedside purposes by using the solution dried on a wad of asbestos and applied to the end of a wooden applicator.

Asbestos paper soaked in Benedict's solution is molded onto the end of a wooden applicator, again thoroughly moistened with the solution and then allowed to dry in air. The test is then carried out by dipping the end of the applicator into the urine or by merely allowing two drops of urine to fall on the end of the asbestos and then gently heating the urine-moistened asbestos over a noncharring flame (Bunsen, stove range, alcohol lamp). A yellow color develops, the intensity of which depends on the concentration of dextrose in the specimen.

A rapid method using asbestos paper and bismuth salts and requiring heat for completion has been devised by Mr. Harold Wright1 of Forest
