What is Forensic Toxicology?

Forensic toxicology is defined as the application of toxicology for the purposes of the law. The field consists of three major subgroups:
1) postmortem toxicology
2) forensic drug testing
3) human performance toxicology

Forensic toxicology utilises disciplines such as analytical chemistry, pharmacology and clinical chemistry to aid medical or legal investigation of death, poisoning and drug use.

Toxicology analysis can be undertaken on a wide range of samples.

What is the best sample to analyse?

Blood samples are the most frequently collected and analysed samples; they are the sample of choice for determining an individual's blood-alcohol concentration in relation to drink-driving offences. Analysis of blood provides the forensic toxicologist with a profile or 'biological photograph' which can then be used to offer an interpretation specific to the case in question.

A typical blood sample collected by a forensic medical examiner, nurse or general practitioner would be approximately 3-5 millilitres (3 -5mls) in volume. This is usually sufficient for alcohol and drug screening analysis.

It is important to keep samples refrigerated (or frozen) and securely packaged in the original, un-opened (often tamper-proof) containers prior to submission.
