Why didn’t you look for drug X, Y, or Z?
We may have looked for the drug but we listed it by a different name. Please first check the generic name vs. brand name of the drug, as these most often will differ. Our results will be reported as the generic name of the drug. For example if you requested testing for ‘Ambien’, the result would be listed as ‘Zolpidem’.
If the drug was not specifically requested and it is not a drug we routinely look for, the testing may not have been added. Please contact us to request additional specific testing. Screening for a specific drug may not be included in the selected testing. Please review your requested panel or test code to insure the screening for the drug of interest was included.
If you need additional help or have any other circumstance, please contact us so that we may resolve your testing questions or concerns.
What if I need a test that ChemaTox does not list or provide?
