This test is not intended for use in employment-related testing.

 

This test is not intended for therapeutic compliance testing. The assay's limits of detection have been established for drugs at overdose levels, which are generally much higher than therapeutic concentrations.

 

This test is not useful for drugs of abuse or illicit drug testing, including benzodiazepines, opioids, barbiturates, cocaine, and amphetamine type stimulants.

 

Chain of custody is required whenever the results of testing could be used in a court of law. Its purpose is to protect the rights of the individual contributing the specimen by demonstrating that it was always under the control of personnel involved with testing the specimen; this control implies that the opportunity for specimen tampering would be limited.
