How do I know the testing results are accurate?

Integrity Sampling uses Dräger drug and alcohol testing equipment for all its workplace testing. This equipment is extremely precise and reliable. In the case of our drug testing equipment, it’s been independently evaluated to be greater than 99% accurate. For alcohol testing, the breathalysers we use have been proven worldwide over millions of tests. It’s also important to note that any non-negative result must be confirmed, in the case of drug tests by independent laboratory analysis. See this post for more details.
