Testing for sugar of urine specimens is the first step in the mass screening for diabetes. Therefore, the method for collection of the urine specimens must be carefully selected. However it is one of the troubles in the mass screening to arrange so many glass vessels for the collection of urine specimens. Although the urine specimen at 2 hour after the breakfast is suitable for testing urine sugar, sometimes it becomes very difficult to collect such specimen by the usual glass vessel method.
The Wetpak method has been deviced by us for the collection of suitable urine specimens in mass screening for diabetes. The procedures are as follows:(1) A piece of clean filter paper treated with 0.2% solution of benzoic acid is soaked with the urine specimen, (2) the piece of the filter paper soaked with urine is put into a small polyethylene bag to be kept wet, (3) the bag is sent to the laboratories, (4) Tes-tape is used for testing urine sugar in the filter paper sent to the laboratories, a strip of Tes-tape must be strongly touched with the wet filter paper.
As the preliminary experiment the urine specimen which contained 0.04% glucose was used for the evaluation of the Wetpak. At the starting of the experiment Tes-tape showed one positive reaction with the urine specimen, 0.04% glycosuria, both directly and in the Wetpak method. Although the urine specimens kept in room temperature (22-28°C) for 30 hours or in a incubator (37°C) for 24 hours failed to show any reaction of glucose with Tes-tape, the piece of the filter paper in Wetpak kept in the same conditions as above showed one positive reaction of glucose with Tes-tape.
It seems to us that the Wetpak method is useful to collect the most suitable urine specimens for glucose test and to send to the laboratories with the minimum degradation of glucose in the specimens.
