This clinically proven staining agent, Toluidine Blue O, is used during exams of sexual assault victims to reveal and visualize any lesions caused during an assault that are not visible without an enhancement agent. Unlike single-use popules products, our dye has 15 applications per bottle, and thus enables multiple locations to be tested for abrasions without stopping to open single-test packaging for each test area. It speeds up the exam for the victim, which reduces their stress. And a multi-use product is more cost effective.
Toluidine Blue O Solution is a convenient pre-mixed solution sold in a 1 ounce (30 ml) bottle. We typically recommend that you purchase several bottles at once so that you always have the product on hand.
