The costly consequences of errors in DOT drug screening
When a drug test comes back as canceled, a carrier must still pay the clinic, lab, and medical review officer for their services. There are also the administrative costs of arranging the test and the driver’s wages to pay.
The canceled test may create other issues also, depending on the test type. Consider the following:
- Pre-employment, return-to-duty, and follow-up drug tests demand a result, so the driver must be sent for another test at the carrier’s expense.
- A canceled random, post-accident, or reasonable drug test is a missed opportunity to learn of an impaired driver. Retesting is not permitted.
- A canceled random drug test cannot be used toward the annual drug-testing rate. A carrier might have to select at a higher rate before the end of the year to compensate for the missed test.
With the potential headache that a canceled drug test brings, is there anything a carrier can do to prevent it? Some situations are correctable, while others always result in a canceled test.

The death of a test: Fatal flaws
The medical review officer (MRO) is required to cancel a test if the lab reports a “fatal flaw” that was observed when processing an incoming specimen.
Fatal-flaw scenarios include:
- The specimen has no chain of custody form (CCF) accompanying it.
- No specimen was submitted with the CCF, in cases where a specimen has been collected.
- The CCF is missing the collector’s printed name and signature.
- Two separate collections were performed using one CCF.
- The specimen ID numbers on the specimen bottle and the CCF do not match.
- A split specimen cannot be redesignated when the primary specimen bottle:
- Has a broken seal,
- Shows evidence of tampering, or
- Has an insufficient sample for analysis due to leakage.
Specific to oral-fluid collections, a fatal flaw occurs when the collector:
- Used an expired device at the time of collection.
- Failed to enter the expiration date on the CCF and the lab confirmed that the device was expired.
A chance to fix the error: Correctable flaws
When a lab discovers a “correctable flaw” when processing incoming specimens, it will attempt to fix the mistake.
The lab must attempt to correct the omission of the collector’s signature on the certification statement on the CCF.
If the MRO’s review of the MRO reveals one of the following, the test is canceled unless remedied:
- Omission of the employee’s signature from the certification statement (unless the employee’s failure or refusal to sign is noted on the “Remarks” line of the CCF).
- Omission of the certifying scientist’s signature on Copy 1 of the CCF for a positive, adulterated, substituted, or invalid test result.
- The collector’s use of a non-federal form or an expired CCF for the test.
In most instances, the problem can be corrected by a written statement by the party (employer, lab, collector, etc.) who is responsible for providing the omitted information.
If the problem is the use of a non-federal form or an expired federal form, the signed statement must:
- Confirm the form and testing complied with Part 40 procedures,
- Indicate the form was used inadvertently or as the only means of conducting the test, and
- Address steps so the error does not happen again.
The written statement for correctable flaws must be transmitted by fax or courier to the MRO on the same business day that the individual learns of the problem.
When the problem is the clinic
Since employers are responsible for the actions of the clinics, it is vital to follow up to ensure collector’s error correction training is performed when required.
If a canceled test was due to mistakes made by the collector, the collector must undergo the training within 30 days of the test. The training covers only the subject matter area that caused the canceled test.
Employers may ask to verify that training occurred. The clinic must provide this documentation according to 40.33(g).
If problems persist with a specific collection site, even if the errors are corrected and the test is saved, the carrier might consider finding another facility for its DOT testing.

Key to remember: A canceled test can cost a carrier money and leave an impaired driver on the road. If the error can be corrected, work with your MRO to correct the mistake. If the error was due to mistakes at the collection site, make sure concerns are communicated to the facility.
