The Department of Transportation (DOT) and the Drug and Alcohol Testing Industry Association (DATIA) are the two main centers for standards and regulations. Unfortunately, these organizations do not keep a registry or list of individuals that are qualified, credentialed, or certified urine/blood/specimen collectors.
Organizations cannot be certified, rather it is the collector that holds the certification.
If you are a Certified Professional Collector (CPC) or Certified Professional Collector Trainer® (CPCT), register today. The registry is managed by Phlebotek.
