A container for collecting a urine specimen has an outer wall, an inner shell and a lid structured to be removeably attached to an upper rim of the container for covering an open top. The inner shell extends down from the upper rim in spaced relation to the outer wall and terminates above a bottom of the container to form a pocket between the inner shell and the outer wall. The pocket traps and captures a suitable testing volume of the specimen within the container in the event the lid is not adequately secured to the container and a portion of the specimen leaks from the container during transport to a testing facility.
