A testing facility shall report single-use test results that meet the standard to be sent to the laboratory for confirmation testing to an employer's review officer, or a designee of the employer's review officer, as soon as the results for the single-use test become available or the next working day. The final conclusion of the testing, which shall include the results of the single-use tests, confirmatory tests, or quality control data, shall be reviewed and the test certified as an accurate report by the responsible individual. The report shall identify the drugs and metabolites tested for, whether positive or negative, and the cutoff for each, the specimen number assigned by the employer, and the testing facility specimen identification number.

D. The drug screen testing facility may transmit results to the review officer by electronic means, including teleprinters, facsimile, or computer, in a manner designed to ensure confidentiality of the information. Results shall not be provided verbally by telephone. The drug screen testing facility shall ensure the security of the data transmission and limit access to any data transmission, storage, and retrieval system.

E. The certified laboratory shall send to the review officer the positive drug test results, which shall be signed by the individual responsible for the day-to-day management of the certified laboratory or the individual responsible for attesting to the validity of the test reports.
