摘要
Substitution of specimens (such as urine specimens) may be detected and even prevented by adding randomization to the collection and routing of specimens. A test taker is required to ingest an ingestible entity the nature of which is concealed from the test taker and others participating in the collection of the sample. The test-taker and unauthorized personnel collecting and routing the specimen are uninformed about fluorescence behavior (or lack of fluorescence) expected for an unsubstituted specimen. The nature of the ingestible entity that a test-taker must take is randomized, and the nature of the ingestible entity is closely held, such as by using bar coding or by using a marker undetectable by the naked eye.
