Special Info
This test is a reflex from Drug Screen 9 Panel, Serum or Plasma (DRGSC9). This test is New York DOH approved.
Clinical Info
Positive Cutoff: 1 ng/mL. The presence of metabolites(s) without parent drug may indicate use of parent drug during the prior week. The absence of expected drug(s) and/or metabolite(s) may indicate noncompliance, 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.
Clinical Limitation
For medical purposes only; not valid for forensic use.
