Abstract
A multiple layer test card includes a waste channel to receive biological waste from an area of the test card utilized for testing biological samples. Multiple compartments in a waste layer of the card are separated from each other by a rib in the waste layer. A first compartment is positioned to receive biological waste from the waste channel. A pass is coupled between each adjacent set of compartments to pass biological waste and air between compartments. A vent in a last compartment provides an air exit from the card.
