The SALIGaE® test is used to determine the possible presences of trace levels of saliva. In this procedure, a small amount of sample is added to test vials that contain a colorless solution. If saliva is present in the specimen, the colorless solution will turn yellow. If saliva is not present in the sample or too dilute to detect, the solution will remain colorless. No reagent preparation required, ready to use 10-minute test Requires as little as 10μl of extract.
