What does the MRO do when a negative or positive test result is also dilute?

(a)When the laboratory reports that a specimen is dilute, you must, as the MRO, report to the DER that the specimen, in addition to being negative or positive, is dilute.#

(b)You must check the “dilute” box (Step 6) on Copy 2 of the CCF.#

(c)When you report a dilute specimen to the DER, you must explain to the DER the employer's obligations and choices under § 40.197, to include the requirement for an immediate recollection under direct observation if the creatinine concentration of a negative-dilute specimen was greater than or equal to 2mg/dL but less than or equal to 5mg/dL.#

(d)If the employee's recollection under direct observation, in paragraph (c) of this section, results in another negative-dilute, as the MRO, you must:#

(1)Review the CCF to ensure that there is documentation that the recollection was directly observed.#

(2)If the CCF documentation shows that the recollection was directly observed as required, report this result to the DER as a negative-dilute result.#

(3)If CCF documentation indicates that the recollection was not directly observed as required, do not report a result but again explain to the DER that there must be an immediate recollection under direct observation.#
