Rapid Dissolve Blue Dye Tablets

Rapid Blue Dissolve Bluing Tablets are placed directly in the toilet at your collection site to ensure sample integrity. 

Blue dye is a coloring agent that is used to detect whether a urine specimen donor has tampered with the specimen provided. 

One tablet of Rapid Blue in a toilet bowl or toilet tank will turn the water blue. If a donor attempts to dilute their own specimen or substitute the entire specimen with the water from either of these sources, the collector will be able to easily detect it.
