When collecting a urine sample for forensic alcohol analysis, use the urine collection kit supplied by Scientific Services Bureau. Title 17, California Code of Regulations, mandates that the subject void his/her bladder prior to collection. Do not collect this void for forensic alcohol analysis. Wait at least 20 minutes after the first void to collect a second void. Submit the second void for forensic alcohol analysis. Mix the contents thoroughly after collection. Seal the urine jar with an evidence seal over the top of the lid. Fill out the yellow label and affix that label to the side of the jar over the evidence seal. Place initials across the seal onto the yellow label.
When toxicological tests other than forensic alcohol analysis are requested, the subject is not required to void his bladder and wait twenty minutes. In these circumstances, a urine sample may be collected immediately.
Offering a urine test is not required for subjects suspected of being under the influence of alcohol only. Refer to the California Implied Consent for Chemical Testing laws for which sample collection techniques may be offered to the subject.
