Hello Courtney.
Blue dye tablets only color the toilet water so an individual will not attempt to water down their urine specimen.

Our current UA use cups, if dipped in food colored water will dye the strip. However if then urine is then poured in the cup, it turns the strips white again. Does/ would this happen with these pills?
