Abstract
Abstract An assaying device is provided for both collecting and analyzing a sample which includes a container and an opening for collecting the sample in a chamber for storing the sample. A cap is provided for sealing the container opening and at least one assay system is attached to the container for chemically analyzing the sample. A channel is provided for enabling a portion of the sample to enter the assay system upon a change of orientation of the container. A tamper-proof device is provided through the use of a releasable seal which permits the sample to enter the assay system only when desired.
