STAT-BLUE Instant Bluing Powder
STAT-BLUE Instant Bluing Powder or other bluing agents are mandated by the federal government in collecting urine samples for drug testing. This product turns the toilet bowl water blue to prevent donor tampering and sample adulteration. The powder dissolves on contact with water and leaves no mess on the collector’s hands—you just point and shoot from the container. Cost per collection is lower than with bluing tablets.
