Once the sample or samples have been collected, we will carry out thorough, rapid analysis and provide you with the results. In most cases, the results of your test are available instantly, though we do recommend additional testing for any non-negative drug or alcohol tests. We take extensive care to preserve test accuracy by ensuring a secure chain of command, proper sample isolation, and taking measures to reduce the risk of contamination or tampering. This means that you can fully rely on the results of your test.
