ABSTRACT:
A diagnostic device is provided comprising a housing including a chamber having one portion open to the exterior of the housing and another portion which is closed to the exterior of the housing with a porous structure such as a hydrophilic membrane disposed across the open portion of the chamber and hermetically sealed to the housing such that after the wettable layer is wetted, the pressure in the closed portion of the chamber of the device can be reduced so that fluid is drawn through the porous structure into the closed portion or interior of the chamber.
