Abstract
Test device for detection and visual indication of a specific analyte in a liquid sample such as a body fluid. The device includes a biodegradable housing, a test strip and a lid. The device is configured for placement in concentrate or dilute test liquid that is for example contained in a vessel. One end of the test strip wicks the liquid being tested into the housing and across a control site and test site which provide visual indication that the device is working correctly and whether the analyte being tested is present in the test liquid. An antibody specific to the antigen being tested may be provided on the test strip. The test device for example detects specific antigens in dilute urine, such that the device may be placed in a toilet bowl after urination.
