For medical purposes only; not valid for forensic use. 
  
Drugs covered: codeine, morphine, 6-acetylmorphine, hydrocodone, 
hydromorphone, oxycodone and oxymorphone. All drugs covered are the non-
glucuronidated (free) form. 

Positive cutoff: 2 ng/mL

The absence of expected drug(s) and/or drug metabolite(s) may indicate 
non-compliance, inappropriate timing of specimen collection relative to 
drug administration, poor drug absorption, or limitations of testing. 
The concentration value must be greater than or equal to the cutoff to 
be reported as positive. A very small amount of an unexpected drug 
analyte in the presence of a large amount of an expected drug analyte 
may reflect pharmaceutical impurity. Interpretive questions should be 
directed to the laboratory.
