Common use of Test Use Clause in Contracts

Test Use. Any urine specimens collected may only be used to test for controlled substances designated or approved for testing and will not be used to conduct any other analysis or test unless otherwise specifically authorized by FHWA regulations. The accompanying Chain of Custody will reflect the nature of the test required. 1. Split Samples. The specimen collected must consist of not less than 45 milliliters of urine, 30 of which is poured into a container for initial testing. The remainder is then poured into a second container for storage. The testing laboratory will retain this sample for at least 60 days from receipt of both specimens by the lab. 2. The split sample confirms contested test results if the primary sample shows a positive test result. 3. Further, the program does not prohibit procedures incidental to an analysis of the specimen for controlled substances. The laboratories are authorized to conduct specific tests to determine if, in fact, the sample has been adulterated, diluted or tampered with. Such tests are approved and consist of tests to determine the specific gravity or to measure the creatine present in the sample.
