Test Code UMTD or LAB2277 Methadone Screen, Urine

Important Note

Drug screens performed at Bronson Laboratory are for medical purposes only. No chain of custody or specimen adulteration testing is performed. All positive results are presumptive. A presumptive positive means that this screening method is positive. A more specific alternative method must be used to obtain a confirmed analytical result. Confirmatory testing is available on request through our reference lab, Mayo. Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly with presumptive positive results.

If employment/legal drug screening is required, contact ProHealth Management Services at 26-341-7547.
