Ensuring accuracy of result interpretations    

Evaluations to detect masking agents

Effective monitoring of pain management therapy and assessment for risk of misuse requires correct interpretation of test results. Because adulterated specimens can generate inaccurate results, having potentially damaging effects on treatment decisions, specimen validity testing is important to assess sample quality prior to testing and result interpretation. Our controlled substance monitoring profiles begin with an adulterant survey to assess for common masking agents and ensure specimen quality. When adulterated specimens are identified, the test order is canceled and reported as invalid, free of charge to the client.
