ABSTRACT:
A specimen cup system for sample testing includes a cup defining sealable first and second regions. A receptacle is formed at a bottom of the first region and extends vertically therein. The receptacle has a first opening defined at the bottom of the first region, a second opening in a radial wall of the receptacle for fluid communication with the first region, and a third opening in the radial wall of the receptacle for fluid communication with the second region. A base having a hollow post is inserted in the first opening of the receptacle. The hollow post has a radial opening formed therein that, when aligned with the second opening, defines a pre-test condition. The hollow post forms a fluid tight seal with the receptacle about the radial opening. The base is coupled to the bottom of the cup in a rotatable fashion such that the hollow post can be rotated to align the radial opening thereof with the third opening in the receptacle to define a test condition. At this point, the base is locked to the cup to prevent further relative rotation therebetween.
