Abstract

A liquid specimen collecting and testing device has two chambers, a first for collecting a liquid specimen and a second for exposing a measured volume preliminary screening aliquot of the specimen to preliminary screening test strips. The first chamber has a catch basin of defined volume which is less than the sample volume. The basin is simultaneously sealed from the rest of the first chamber, thus separating and apportioning the measured volume preliminary screening aliquot from the collected volume. Simultaneously, an opening made leading from the basin to the second chamber initiating the preliminary screening test. Thus intermingling of a preliminary screening aliquot and a remainder aliquot is avoided.
