Forensic Toxicology Sections
|
For effective casework management, the Forensic
Toxicology Sections are split into Analytical Toxicology,
Urinalysis, and Drink-Driving Units, each with its distinctive
functions.
The Analytical toxicology Unit examines
biological materials (mostly ante- or post-mortem specimens
of human origin) such as blood, urine and liver, as well as
related materials found at scenes for drugs or poisons. The
findings assist the Coroners, Forensic Pathologists of the
Department of Health, Clinical pathologists of the Hospital
Authority and the Police Force in the investigation of criminal
offences and suspicious deaths where drugs or poisons are
implicated.
|
The Urinalysis Unit analyses urine samples
submitted by methadone clinics of the Department of Health from
drug addicts registered in the Methadone Maintenance Programme.
It is also responsible for the analysis of opiate and non-opiate
drugs of abuse in urine samples submitted by the Social Welfare
Department, the Correctional Services Department, the Police Force
and other drug rehabilitation centres, taken from young offenders
placed under their monitoring programmes.
The Drink Driving Unit was set up in December
1995 as a result of changes to the Road Traffic Ordinance enacted
at that time to make it an offence to drive with alcohol in breath,
blood or urine exceeding the corresponding statutory limits. Effective
from 1st October 1999, the Road Traffic Ordinance has been revised
and tightened to make it an offence to drive with greater than 22
microgrammes (ug) of alcohol per 100 mL of breath, 50 milligrammes
of alcohol per 100 mL of blood, or 67 milligrammes of alcohol per
100 mL of urine. Drivers found to have 22-37 ug/100 mL of breath
alcohol as tested by police using approved breathalyser have the
option of having their blood or urine samples analysed by the Unit
for alcohol content instead of just accepting the breathalyser results.
The three units also provide expert advice to clients
and courts on an as-need basis on issues of pharmacology and toxicology
of drugs and alcohol.

From 2010 onwards, the previous target of "judicial confirmation" under "drug urinalysis" has been re-named to "judicial confirmation (routine)" to exclude cases under the pilot scheme for enhanced probation as mentioned in the second bullet point of paragraph 16, which are subject to a separate target of "judicial-confirmation (enhanced probation)". |
