-DOT "Consortium Pool"
Consists of multiple DOT mandated employers working together to achieve the DOT testing rates of 50% for controlled substances and 10% for alcohol throughout the calendar year. As of September 2011, the Consortium pool size consists of 105 employers, with a grand total of 858 drivers. Selections take place on a quarterly basis. Participating members each have an equal chance of being selected 1-4 times per year, or might never be selected.

Consortium pool includes only drivers who operate a Commercial Motor Vehicle, as defined in CFR 382.107; a) drives a vehicle that weighs 26,001 lbs or more, b) drives a vehicle designed to transport 16 or more passengers , or; c) drives a vehicle of any size that is used in the transportation of Hazardous Materials and requires placards.

-DOT "Individual Pool"
Consists of an employer performing selections to include only their own CDL drivers (as defined in CFR 382.107). Employer may choose to select anytime throughout the calendar year (weekly, monthly, bi-monthly or on a quarterly basis).

- Non-DOT (Non-mandated)
Non-DOT stands for Non Department of Transportation testing. This type of testing is not regulated by any federal agency. Based on the employers' company policy, the employer may choose to include office, warehouse, factory, sales, and any other Non-DOT positions into this program. It is prohibited by DOT federal guidelines to combine DOT and Non-DOT testing. Based on company policy, the employer may choose to make selections anytime throughout the calendar year on a weekly, bi-monthly or quarterly basis, and at rates choice.


When choosing participants for a random test, the computer uses a basic and complete method to ensure unbiased selections. It is a double-blind selection method-one in which neither the administrators nor the participants can predict or affect the outcome. Sometimes participants challenge a particular random selection or even the entire process. This drug testing compliance software utilizes an exclusive system called RandSelâ„¢ Tracking that records actions that could affect the outcome of any random selection. The RandSelâ„¢ Tracking system has proven itself in every challenge to date. -DrugPak


Prior to a selection, the employer will be required to update their random eligibility list. The Designated Employer Representative (DER) will receive via fax a list of employees who were previously participating in the random program. The list of names must be verified and signed, noting that the list is correct and/or noting corrections, additions, or deletions, and returned to our office by either fax or email within 5 days of receipt.


After a random selection takes place, the DER is provided with individual sealed notification form(s) for each employee selected. Notification forms must be given out to the employees only on the day that he/she is to be tested. In the event that the DER himself is selected, he/she must report immediately for testing once the notification form is received. Employees selected for Alcohol testing must report for testing right before, during, or right after performing safety sensitive functions (driving). Selected participants must comply with testing within the specified selection period.


Selected participants are to report to previously designated medical clinic(s) for the collection and/or testing process. Medical facilities used for testing must have certified personnel and equipment to perform drug screen collections and/or alcohol testing as per DOT guidelines. Based on the number of participants selected, the employer may choose to perform "on-site" collection; service may not be available in all areas.


Employer may choose to receive the initial test results via secure fax, verbal (voicemail), or via secure e-mail. Initial reports are followed with written confirmation via US mail.

Results to include, positive, substituted and adulterated are reported directly from the laboratory to the certified Medical Review Officer (MRO). The MRO will review the results, interview the donor, and determine validity of the test result. Once a final determination has been made, the DER will be contacted with the MRO findings, followed by written confirmation in the mail.

Negative results can be expected within 24-48 hours from the time the sample is received at the laboratory; positive results may take up to 72 hours.


All information pertaining to the drug and alcohol-testing program is maintained, in a secure location with controlled access, according to DOT guidelines. Negative Results are stored for 1 year, and positive findings are stored for 5 years.


Statistical reports are routinely provided to each consortium member on a quarterly basis and at the end of each calendar year. Employers may request customized reports anytime through the year.
