Abstract
An assaying system for determining the presence of particular illicit substances in human physiological fluid, consisting of a collection cup, a collection cup lid, and a test card with assaying means, quality control means and adulteration detection means which is secured to the collection cup lid. The assaying means contemplate the addition of control positives such that a pre-determined number of assaying systems would be configured so that a false positive indication would be given by the assaying means in addition to any true positive results which may be present. Accordingly, it would initially be impossible to distinguish true test-positives from control positives, and thus the anonymity of a true test-positive donor individual would be protected. All donor individuals testing negative would be immediately discernible.
