Abstract
A fluid specimen collecting and testing device has two chambers each sealable by a lid. A first chamber has a portion of the specimen volume for carrying out a field test. A second chamber preserves an untainted portion of the fluid for more rigorous laboratory testing. A volume of fluid is temporarily allowed to pass from one chamber to the other through a sealable passageway. One lid carries one or more chromatic graphic reaction testing strips.
