Forensic Toxicology
Our work is carried out within an accredited laboratory environment, with robust quality systems in place to ensure accuracy, reliability and consistency. We support clients who require scientifically sound results and clear interpretation to assist with informed decision making.
Analytical Services International (ASI) provides forensic toxicology services that support professionals involved in criminal, civil and coronial casework. Our scientists apply advanced analytical techniques to help determine whether alcohol, drugs or other toxic substances may be relevant to the circumstances of a case.

Toxicology Analysis
Our toxicology service includes the analysis of a wide range of compounds that may be encountered in forensic casework. This includes alcohol, prescription medicines and other substances of interest. All analysis is performed using validated techniques and is supported by quality assurance processes.
Our reports are designed to be clear and accessible, providing the information required to understand the significance of the findings within the context of each case.
Specialist Insulin and Modern Diabetes Drug Testing
ASI provides specialist analytical support for cases where hypoglycaemia, metabolic disturbance or the use of diabetes related treatments may be a consideration. Using sensitive LC-MS/MS methodology, we can quantify:
Insulin
Insulin analogues
C peptide
GLP 1 agonists such as semaglutide and tirzepatide
These assays support enquiries where understanding the presence or absence of these compounds may assist with case interpretation.
Drug Material Testing
As an extension of our toxicology capability, ASI offers drug material testing for the identification of certain substances submitted as part of an investigation. This service assists clients who require reliable confirmation of material composition to support decision making or reporting requirements.
Results are provided in a clear and concise format, with interpretation where appropriate.
Toxicology Interpretation
Our scientists provide expert interpretation to help clients understand the potential relevance of analytical findings. This may include discussion of pharmacology, drug interactions, concentration ranges, timing considerations and other factors that can influence the interpretation of toxicology results.
Each report is tailored to the specific questions raised and reflects current scientific understanding and literature.

FAQs: All You Need to Know
Do you provide toxicology testing for insulin, including medicines such as Humulin, Actrapid or Lantus?
Yes. We offer specialist LC-MS/MS analysis for human insulin and insulin analogues that may be relevant in forensic or coronial investigations.
Can you detect rapid acting insulin analogues like Humalog, NovoRapid or Apidra in forensic samples?
Yes. Our methods can detect and quantify commonly used rapid acting insulins when required for investigative or coronial purposes.
Do you offer testing for GLP-1 agonists, including semaglutide (Ozempic, Wegovy, Rybelsus) and tirzepatide (Mounjaro, Zepbound)?
Yes. We offer analysis of GLP-1 agonists and related compounds in cases where the presence or absence of these medicines may be relevant to interpretation.
Can you measure C-peptide alongside insulin to assist with forensic interpretation?
Yes. C-peptide can be included where interpretation may benefit from distinguishing endogenous insulin from administered insulin or insulin analogues.
What types of investigations require testing for insulin or GLP-1 agonists?
These assays may be relevant in coronial investigations, unexplained hypoglycaemia, suspected administration, medication-related concerns or cases where metabolic disturbance may require clarification.
