What does a Probable Cause testing code signify?

A Probable Cause testing code signifies that testing is initiated due to suspicious behavior. This type of testing is typically triggered when there is reasonable belief or evidence suggesting that an individual may have engaged in substance misuse. Such a scenario might arise from observed behavior, credible information, or previously recorded instances that raise concerns about an individual's potential alcohol or drug use. In the context of military protocols, this ensures that service members are held accountable for their actions and that any substance abuse issues are addressed promptly to maintain unit readiness and safety.

While routine testing based on random selection is a common practice to maintain a drug-free environment, it doesn't involve specific behavioral indicators. Similarly, testing for Soldiers returning from deployment and annual health assessments are proactive measures focusing on health and wellness rather than addressing immediate concerns related to substance use. Probable Cause testing is a reactive measure specifically targeting behavior that warrants further investigation and action.
