Specimen Processing. Laboratory personnel will normally process urine specimens (sample A) by grouping them into batches. When conducting the screening test, every batch shall contain an appropriate number of standards for calibrating the instrumentation and a minimum of 10 percent controls. Current /SAMHSA standards in affect at the time of collection, and, for those drugs without a /SAMHSA standard, Attachment "C" shall be used for the immunoassay screening test which will be used to eliminate "negative" urine samples from further consideration. Detailed screening and quality assurance procedures are discussed in the Laboratory Procedural Manual. Written documentation shall be maintained by the laboratory showing details of all the screening tests done under this program. These data may be reviewed by consultants to the Union. All samples that initially screen positive shall be stored in the locked employee Drug Testing freezer in the Toxicology Section until conformation tests are complete.
