Immunoassay

This assay detects Fentanyl at 1 ng/ml and higher. Butyryl and Acetyl Fentanyl analogues are also detectable. The norfentanyl metabolite is not detected.

Note: External studies have shown that labetalol and trazadone may cause false positives with this test.

 

Note:

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