Abstract
A chromogenic composition for detecting spilled blood includes a mixture of an acidified aqueous solution containing reduced FD&C Blue #1 and hydrogen peroxide. The chromogenic composition has a relatively long shelf life and will produce a bright blue visible color when contacting blood, thereby being useful for detecting spilled blood and blood trails from wounded game.
