Appropriate interpretation of results is key to the overall value of drug testing.
Drug testing is an essential part of the overall patient care plan and provides objective information that may be useful in assessing adherence, protecting the patient, promoting accountability, initiating important conversations, and preventing diversion. The science of drug testing is complex, and understanding concepts such as testing methodology, period of detection, drug metabolism and specimen type differences are important to appropriate interpretation.
Developed by Aegis toxicology experts, the Clinical Reference Guide delivers practical, evidence-based information on drug testing methodology, detection windows, drug metabolism, and specimen-specific considerations. Designed for busy healthcare professionals, this comprehensive resource provides the clinical context and scientific support needed to confidently interpret results and maximize the value of drug testing in patient care.
