Abstract
A sample test device is provided that includes a body having an insertion surface spaced apart from a distal end portion and a fluid manipulating assembly disposed in the distal end portion. A mixing receptacle is defined in the fluid manipulating assembly and provides a volume to mix a test mixture. A plunger is disposed in the body and creates a positive air pressure in the mixing receptacle when inserted into the body. A test die is disposed in the fluid manipulation assembly and a fluid path extends from the mixing receptacle to the test die. Activation of the plunger creates a positive pressure in the mixing receptacle to force the test mixture to flow from the mixing receptacle to the test die.
