Abstract

A collection system for collecting, testing and transporting liquid biological specimens that limits exposure of a tester to the liquid sample and keeps the collected samples pristine even after exposing some of the sample to test strips. The system includes a collection body for receiving and holding a liquid sample, a lid that is coupled to the body, and a test strip housing. The lid includes a transfer conduit while the test strip housing includes an opening defined within the test strip housing. The transfer conduit and the opening are aligned when the test strip housing is coupled to the lid. When the system is moved or tilted, some of the liquid sample moves through the transfer conduit and the opening into the test strip housing.
