Cocaine and Metabolite Confirmation, Chain of Custody, Random, Urine
Use
The test is useful for detecting and confirming drug abuse involving cocaine. It provides confirmatory analysis to ensure the validity of positive results and safeguards the integrity of the specimen by following a strict chain of custody, which is essential when results may be used in legal situations. The presence of cocaine or its major metabolite, benzoylecgonine, indicates cocaine use within the past 4 days.
Special Instructions
The test is not intended for use in employment-related testing. Chain of custody is required whenever results could be used in a court of law to protect individual rights and ensure specimen integrity.
Limitations
Positive results indicate cocaine use but do not correlate with pharmacologic or toxic effects. No significant cautionary statements are associated with the test. Laboratory results are increasingly disputed, emphasizing the importance of confirmatory testing.
