HAR §11-113-18. §11-113-18 Laboratory procedures for urine specimens

(a) When a shipment of specimens is received, laboratory personnel shall inspect each package for evidence of possible tampering and compare information on specimen bottles 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 the chain of custody forms attached to the shipment shall be immediately reported to the third party and shall be noted on the chain of custody form which shall accompany the specimens while they are in the laboratory's possession. (b) Specimen bottles or containers will normally be retained within the laboratory's accession area until all analyses have been completed. Aliquots and the laboratory's chain of custody forms shall be used by laboratory personnel for conducting tests. (c) Specimens that do not receive a test within seven days of arrival at the laboratory shall be placed in secure refrigeration units at temperatures not exceeding ten degrees Centigrade. Emergency power equipment shall be available in case of prolonged power failure. (d) When conducting either screening or confirmatory tests, each batch of specimens shall contain an appropriate number of standards for calibrating the instrumentation and a minimum of ten per cent of controls. (e) Except for additional testing to determine the validity of the specimen, no laboratory shall test for any substance which is not included in a written statement from the third party specifying the substances to be tested for. Such additional tests may include the following: (1) Creatinine and specific gravity: the specimen is considered "diluted" if the creatinine concentration is greater than or equal to 2 mg/dl but less than 20 mg/dl and the specific gravity is greater than 1.001 but less than 1.003. The specimen is considered "substituted" (i.e., the specimen does not exhibit the clinical signs or characteristics associated with normal human urine) if the creatinine concentration is less than 2 mg/dl and the specific gravity 113-19 2783
