Clinical Info:

The assay results distinguish between positive and negative specimens:
- positive indicating specimens contain detectable methadone metabolites;
- negative indicating specimens do not contain methadone metabolites, or the methadone metabolites are present in concentrations below the cutoff level for this assay.
-The cut-off level of detection for this assay is 300 ng/mL.

Additional Information:

Detect the presence of methadone metabolites in urine. This is a screening test and will reflex to confirmatory testing where indicated.

Sample Collection:

Clean catch or catheterized urine in a clean and sterile container with no preservatives.

Test Limitations:

1. The assay is designed for use only with human urine.

4. Interpretation of results must take into account that urine concentrations can vary extensively with fluid intake and other biological variables.
5. Immunoassays that produce a single result in the presence of a drug and its metabolites cannot fully quantitative the concentration of individual components.

Specimen Handling Instructions:

The urine should be collected in a clean, dry container. Urine collected at any time of day may be used. Urine specimens containing visible particles should be centrifuged, filtered, or allowed to settle to obtain a clear specimen for testing.
