FOBT--how it works: If you're using the old hemoccult slide, you'll notice its two-sided. You place your specimen on one side, and close the lid. The doctor or lab, when developing your specimen, turns the card over, opens the back (its clean on that side), and applies the developer solution which soaks thru to your specimen. If a color change, the doctor or lab knows your specimen contains invisible blood.
