| Interpretive Data: |
This is a screening test only. Positive results are not automatically reflexed to a confirmatory test (GC/MS, GC/FID, and/or LC-MS/MS) unless requested separately. Confirmatory testing for drugs and/or drug classes detected by this screening test is recommended.
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, diluted/adulterated urine, or limitations of testing. The concentration at which the screening test can detect a drug or metabolite varies within a drug class. The concentration value must be greater than or equal to the cutoff to be reported as positive. Interpretive questions should be directed to the laboratory.
For medical purposes only; not valid for forensic use.
