Abstract: An assaying device composed of a test cartridge/cassette and cap/cover. When attached, the cap/cover seals the top of a sample well/opening on the cartridge/cassette in a fluid tight manner, to protect from contact with and contamination of the tested sample (for example, urine for drug testing), provide easier, cleaner handling of the test cartridge/cassette and prevent intermixing of another sample.
