Split Specimen DOT Drug Testing

You are here:

Optional Split Specimen Testing added for non-DOT Orders

All DOT urine panels for Quest and LabCorp are automatically ordered as split specimen, and this has now been added as an optional setting for non-DOT screens as well. Split specimen testing lets the vendor know that they should split the applicant’s urine specimen into two containers. One sample is used for the initial test, and if it comes back positive, the second sample is used for a confirmation test. This allows the applicant/employee to request a second substance abuse screening be done at a different lab as well and helps ensure proper procedures are being followed. In some cases, the applicant will be contacted by the physician reviewing the results to make sure there are no medical or other reasons for the result.
