signs of contamination. The urine is then split into two separate specimen containers (A, or <br />"primary," and B, or "split") with identifying labels and security seals affixed to both. The <br />collection facility will be responsible for maintaining a proper chain of custody for delivery of <br />the sample to a DHHS-certified laboratory for analysis. The laboratory will retain a sufficient <br />portion of any positive sample for testing and store that portion in a scientifically -acceptable <br />manner for a minimum 365-day period. <br />If an employee fails to provide a sufficient amount of urine to permit a controlled substance test <br />(45 milliliters of urine), the collector will discard the insufficient specimen, unless there is <br />evidence of tampering with that specimen. The collector will urge the driver to drink up to 40 <br />ounces of fluid, distributed reasonably over a period of up to three hours, or until the driver has <br />provided a sufficient urine specimen, whichever occurs first. If the driver has not provided a <br />sufficient specimen within three hours of the first unsuccessful attempt, the collector will cease <br />efforts to attempt to obtain a specimen. The driver must then obtain, within five calendar days, <br />an evaluation from a licensed physician, acceptable to the MRO, who has expertise in the <br />medical issues raised by the employee's failure to provide a sufficient specimen. If the licensed <br />physician concludes the driver has a medical condition, or with a high degree of probability <br />could have, precluded the driver from providing a sufficient amount of urine, the City will <br />consider the test to have been canceled. If a licensed physician cannot make such a <br />determination, the City will consider the driver to have engaged in a refusal to test, and will take <br />appropriate disciplinary action under this policy. <br />The primary specimen is used for the first test. If the test is negative, it is reported to the MRO <br />who then reports the result, following a review of the CCF Form for compliance, to the City. If <br />the initial result is positive or non -negative, a "confirmatory retest" will be conducted on the <br />primary specimen. If the confirmatory re -test is also positive, the result will be sent to the MRO. <br />The MRO will contact the driver to verify the positive result. If the MRO is unable to reach the <br />driver directly, the MRO must contact the City who will direct the driver to contact the MRO. <br />Review of Test Results <br />The MRO is a licensed physician with knowledge and clinical experience in substance abuse <br />disorders, and is responsible for receiving and reviewing laboratory results of the controlled <br />substances test as well as evaluating medical explanations for certain drug test results. Prior to <br />making a final decision to verify a positive test result, the MRO will give the driver or the job <br />applicant an opportunity to discuss the test result, typically through a phone call. The MRO, or a <br />staff person under the MRO's supervision, will contact the individual directly, on a confidential <br />basis, to determine whether the individual wishes to discuss the test result. If the employee or job <br />applicant wishes to discuss the test result: <br />• The individual may be required to speak and/or meet with the MRO, who will review the <br />individual's medical history, including any medical records provided. <br />• The individual will be afforded the opportunity to discuss the test results and to offer any <br />additional or clarifying information which may explain the positive test result. If the <br />employee or job applicant, believes a mistake was made at the collection site, at the labor, on <br />a chain -of -custody form, or that the drug test results are caused by lawful substance use, the <br />employee should tell the MRO. <br />56 <br />
