Toxicology confirmation testing is performed to positively identify specific compounds or substances within an individual’s system in a more detailed way than what’s normally done with routine testing. It’s done by matching substances to a commercially prepared reference.
WHY TOXICOLOGY CONFIRMATION IS DONE
Toxicology confirmation may be done simply to verify results of the first test that was performed. It can also be done if a patient tested positive for a certain class of drugs on their initial test to identify the specific drug within that class. For instance, a patient can test positive for opiates on an initial tox screen and a toxicology confirmation may reveal that the opiates involved are fentanyl and oxycodone. Additional reasons for requesting toxicology confirmation may include:
- Verification that a patient is taking their medication(s) as prescribed
- Identification of illicit drugs or medications not prescribed to a patient
- Showing possible correlations between medication usage and patient behaviors
- Confirmation of specific medications an individual indicated they were taking for valid medical reasons prior to drug testing
