A collection and testing cup for fluid characterization is disclosed. The cup has a lid assembly with a tamper evident closure; a cylinder that extends into the fluid in the collection cup, also with a tamper evident closure; a piston with a conduit and one-way valve through which a portion of the fluid can be forced into an isolation chamber separate from the main collection cup for testing. The lid assembly cylinder is configured with an aperture or passage near the bottom of the cylinder to allow a small portion of fluid to enter the lower portion of the cylinder from the collection cup chamber and a piston with a central conduit and valve initially positioned near the top of the cylinder adjacent to the lid. The piston, when pushed down the cylinder, closes the aperture communicating with collection cup chamber and forces a predetermined volume of fluid from the lower portion of the cylinder through the conduit and valve to the upper portion of the cylinder, isolating a portion of the fluid sample from the fluid in the collection cup chamber. The valve prevents the fluid from returning to the lower portion of the cylinder and to the collection cup chamber. A testing device may be inserted into the fluid sample at the upper portion of the piston for characterization of one or more analytes in the fluid sample.
