Subchapter 5 - Drug Screen Testing Facilities
Section 310:638-5-3 - Security and chain of custody

(a) Drug screen testing facilities shall be secure at all times. They shall have in place sufficient security measures to control access to the premises and to ensure that no unauthorized personnel handle specimens or gain access to testing facility processes or to areas where records are stored. Access to these secured areas shall be limited to specifically authorized individuals whose authorization is documented. With the exception of personnel authorized to conduct inspections on behalf of federal or state agencies, all authorized visitors and maintenance and service personnel shall be escorted at all times. Documentation of individuals accessing these areas, dates, time of entry, and purpose of entry shall be maintained.

(b) Drug screen testing facilities shall use internal chain of custody procedures to maintain control and accountability of specimens from receipt through completion of screening, reporting of results, during storage, and continuing until final disposition of specimens. The date and purpose shall be documented on an appropriate chain of custody form each time a specimen is handled or transferred, and every individual in the chain shall be identified. Authorized drug screen testing facility personnel shall be responsible for each specimen or aliquot in their possession and shall sign and complete chain of custody forms for those specimens or aliquots as they are received.

(c) When specimens are received, drug screen testing facility personnel shall inspect each package for evidence of possible tampering and compare information on specimen bottles and containers within each package to the information on the accompanying chain of custody forms. Any direct evidence of tampering or discrepancies in the information on specimen bottles and containers and the agency's chain of custody forms shall be immediately reported to the employer and shall be noted on the drug screen testing facility's chain of custody form which shall accompany the specimens while they are in the drug screen testing facility's possession.

(d) Specimen bottles shall normally be retained within the drug screen testing facility's accession area until all analyses have been completed. Aliquots and the drug screen testing facility's chain of custody forms shall be used by drug screen testing facility personnel for conducting initial screening tests.

(e) Urine specimens shall be tested for adulteration.

(f) Testing facilities shall perform integrity checks on saliva specimens as required by facility policy.
