Abstract: A urine collection apparatus includes a tamper-proof, one way valve to make sure that freshly voided samples of urine are not tampered with. A chemical type thermometer is located in the reservoir to make sure that the urine sample is fresh when collected. An enzyme poison detector station helps to insure that bleach or other chemicals haven't been added to the urine to adulterate the specimen. The one way valve preferably comprises a trap door that closes as the urine sample fills up the reservoir. The presence of an adhesive substance around the edge of the trap door keeps the trap door shut after the urine sample has been collected.
