What steps must operators of collection sites take to ensure the integrity and security of the urine collections?
A bluing agent must be placed in all toilets used for specimen collection, ensure that no soap, disinfectants, cleaning agents, or other possible adulterants are present, inspect site to ensure no other foreign or unauthorized substances are present. You must also tape or secure shut any movable toilet tank top and secure areas and items (trash receptacles, paper towel holders, under sink area, ledges) that appear suitable for concealing contaminants.
