When can the MRO notify an employer of a positive drug test result?
The MRO may not notify the employer of a positive test until he/she has verified the test as positive. Verification requires that the MRO review the chain of custody documentation, contact the employee, review any documentation of a legitimate medical explanation for a positive test, and determine that the positive resulted from unauthorized use of a controlled substance. The MRO is not required to delay verification pending the outcome of the reanalysis or the split analysis. Only upon verification shall the MRO notify the employer of the positive result, and the employer shall then remove the empln. Once having received notice of a verified positive result from the MRO, the employer shall not delay removal of the employee from safety sensitive duties pending the outcome of the reanalysis or the split analysis.
