ASCERTAIN FORENSCIS AT REDWOOD TOXICOLOGY LABORATORY, INC.

Exhibit A SCOPE OF WORK Ascertain Forensics at Redwood Toxicology Laboratory, Inc. (Ascertain Forensics at RTL) proposes to provide the following services to the City of Pleasanton. 1. Ascertain Forensics at RTL is currently accredited by American Board of Forensics Toxicology and approved by the California Department of Public Health in compliance with California Administrative Code Title 17 to perform Forensic Alcohol Analysis. Ascertain Forensics at RTL’s toxicology staff currently has six (6) forensic alcohol analysts. 2. Ascertain Forensics at RTL will provide kits for the collection of blood or urine samples for the purpose of analysis for alcohol and/or drugs. a) Ascertain Forensics at RTL will routinely provide the City of Pleasanton with supplies necessary to collect and ensure proper chain-of-custody for samples. These supplies include collection tubes (vacutainer type) for blood that have a FAS seal from vial to stopper allowing for identification of the proper approved collection vial, non-alcoholic disinfectant wipes and tamper-proof transfer bags. A representative number of tubes from each lot supplied have undergone testing for any contamination from the manufacturer to ensure accurate analytical results for alcohol analyses. These same tubes are used for blood draws and for drug analyses. Two-ounce urine collection containers without preservative and tamper proof transfer bags are supplied for urine drug screens. Both blood vacutainer tubes as well as urine containers are provided with tape-seals that the officer can complete at the time of collection indicating the subject's name, the date and time of collection, the officer's name, and the name of either the urine collection witness or the person drawing the blood sample. These labels are designed to go over the cap or stopper from the sides of the tube or container, as directed by the Uniform Standards for Withdrawal, Handling and Preservation of Blood Samples for Ascertain Forensics at RTL. b) Chain of custody forms, security seals and boxes or envelopes for specimen shipment are provided by Ascertain Forensics at RTL. The chain of custody forms include space for the suspect's name, arresting agency,arresting officer,violation,date and timeof sample collection, and other demographic information. Specimens for each case will be placed in a cardboard box or evidence envelope and sealed with the provided security seal. The box/envelope and corresponding chain of custody form will be placed into a double pouch specimen baggie and sealed. Then placed in a large recloseable bag, that bag will be placed into a bubble sealable pouch and then placed in an opaque, FedEx lab pack and sealed. The FedEx shipping label will be placed onto the lab pack, and a tracking number sticker from the label should be retained by staff. The FedEx bag can be delivered to a FedEx hub or a drop off location – to minimize additional ‘touches’ of the specimen/lab pack. The lab packs are then scanned by FedEx and shipped overnight to Ascertain Forensics at RTL. Supplies will be provided by Ascertain Forensics at RTL.
