Completion of a DOT drug test requires the following steps:
- Driver shows up at the clinic when a Chain of Custody is signed by the driver
- Sample is taken from the driver and mailed to the lab
- Lab completes drug test and posts on their portal for IPS to report
If everything proceeds normally, Drug Test results come out within 2 days or sooner. However, Drug Test Results could be delayed due to the following reasons:
- Shipment delay due to weather or other reason
- Paperwork mistakes which require Affidavit documents to be sent to the lab
- Sample is lost in the process
- Driver’s test result does not come out as NEGATIVE during the first run requiring reconfirmation tests
