(a) Methods of determining the presence of a drug or other impairing substance are by collection and analysis of urine sample. The employee must provide a urine specimen into a collection container. The collection site personnel, in the presence of the employee, puts the specimen into two bottles. Thirty (30) milliliters (ml) must be poured into one bottle, to be used as a primary sample (bottle A). At least 15 ml must be poured into the other bottle (bottle B), to be used as the split sample. Bottle B is stored at the testing laboratory rather than at the collection site. Both specimens are labeled with the same identification information and specimen ID (bar code) number. After a specimen is provided, the bottles do not leave the employee's sight until they are completely and correctly labeled and sealed in a tamper-proof bag for delivery to the laboratory.

(b) Once the urine specimen has been collected, and still in view of the employee, the collector will legibly label the urine specimen entering all the information to identify the specimen on the bottle, to include, and not limited to date, collector's initials, test type requested, a specimen number, identifier of person providing urine, i.e., medical record number, or other individualized number (driver's license, social security number, employee position number), employee's birthdate on specimen label, employee's signature, with employee signed date and time on specimen label.

(c) Unless there is reason to suspect tampering during the test, the test occurs in a rest room, stall, or enclosure ensure privacy. When there is reasonable suspicion the individual may tamper with the specimen, CALPIA may specify that an observed collection is required.
