Drug Metabolism

The tables below show some of the more common metabolic pathways for opiates and benzodiazepines. If you have specific questions about a patients test results, our laboratory staff members are at your disposal.

Simplified Reports

Metabolism is quite complex, our 2-page report summarizes our findings into three easy to interpret categories:

  • Consistent – You prescribed it, we found it
  • Inconsistent Negative – You prescribed it, but it wasn't there
  • Inconsistent Positive – It wasn't prescribed and shouldn't be there
