Dr Simon Elliott, Founder & DirectorToxicology UK responds with a specialised forensic toxicology model. It combines accredited analytical testing, specialist interpretation and casework expertise into one integrated process that helps Coroners, pathologists and investigator move from unexplained deaths and inconclusive findings to clear, scientifically defensible conclusions.
"Families need answers, and Coroners need confidence. Our role is to ensure the science provides both," Dr Simon Elliott, founder & director.
Specialists at Every Step
Toxicology UK undertakes its analytical testing at NMS Labs in Philadelphia, an internationally recognised forensic laboratory capable of detecting many hundreds of substances, including prescription medicines, drugs of abuse, alcohol and many Novel Psychoactive Substances. Continuous internal quality controls, external proficiency testing and internationally recognised laboratory ISO standards ensure that every analytical result is accurate, traceable and legally defensible.
Toxicology UK's team of experienced forensic toxicologists then interprets those findings alongside the deceased's medical records, prescription history, known drug use, pathology findings and the circumstances surrounding the death. Contextual assessment transforms analytical data into scientifically defensible conclusions that directly support the Coroner's investigation.
Advances in logistics and tracking have made this model practical. Samples can now be transported safely and securely around the world while maintaining their integrity.
It also has particular relevance in jurisdictions where analytical laboratory capacity is limited. Toxicology UK demonstrates how organisations can access internationally accredited analytical testing and retain expert interpretation within their own legal and medical framework.
Communicating Science With Greater Clarity
Its licensed Toxicological Significance Score (TSS) complements the model, making reports easier for Coroners, pathologists and families to interpret.
Originally developed by Dr Elliott while working with the European Union to assess designer drugs, the framework provides a structured and consistent way of evaluating each detected substance. It helps communicate the likely contribution of detected substances within the overall circumstances of the case. Factors such as the drug’s pharmacological properties, the concentration detected, the deceased's medical and prescription history and potential interactions between multiple substances are considered.

The results are then presented using a low, medium or high significance rating, supported by the detailed scientific interpretation. Coroners and pathologists can quickly identify the substances most relevant to determining the cause of death while making it easier for families to understand the findings without specialist medical knowledge.
Since introducing it, Toxicology UK has received positive feedback from Coroners, pathologists and families. Dr Elliott also recognises the potential to make the framework available to other forensic organisations through licensing agreements internationally.
Looking Beyond Initial Assumptions
Clear interpretation is only possible when the underlying investigation is equally comprehensive.
The early stages of a death investigation are often guided by incomplete information, based on police enquiries and information gathered from family and friends about possible drug use. As the investigation progresses, new information regarding undisclosed medications, recreational drug use or digital evidence indicating an interest in a particular substance may emerge.
When a substance that was not initially suspected becomes relevant later in the investigation, investigators need to know whether it has already been tested for and excluded. Toxicology UK therefore recommends broad toxicological screening at the beginning of every investigation. Testing for a wide range of substances without preconceived expectations helps investigators confirm what was present and what can be excluded. This minimises the risk of bias, reduces the need for repeat testing when new evidence comes to light and gives Coroners greater confidence that the investigation has considered every reasonable possibility.
While broad toxicology screening provides a strong starting point, it cannot answer every question. Some substances have unique chemical properties that require targeted analytical methods and will not appear in a routine screening. Based on many years of experience, knowing when to pursue additional lines of enquiry distinguishes Toxicology UK's investigative approach.
In one investigation, an individual was found dead at home with no obvious injuries or underlying medical condition that could explain the death. A comprehensive toxicology screen identified only prescribed medications and a small amount of alcohol, both at levels consistent with normal therapeutic or social use. Conventional testing had effectively ruled out the most common causes, yet it failed to find the cause of death.
The absence of a clear toxicological explanation prompted Toxicology UK's scientists to revisit the wider circumstances of the case. During discussions with investigators, they learned that a bowl of custard had been found beside the deceased, which prompted a different line of enquiry. They recommended targeted testing for an industrial chemical commonly used as a food preservative that has increasingly been associated with fatal poisonings and can be taken by mixing in with food. Because the substance requires specific analysis, it would not appear in a general toxicology screen. Subsequent testing confirmed its presence at fatal concentrations, ultimately establishing the cause of death and providing the Coroner and the family with the clarity they had been seeking.
"The laboratory provides the data. Experience determines whether you've asked all the right questions. If you don’t look, you don’t find," says Dr Elliott.
Every postmortem investigation represents a person whose death deserves to be understood and a family waiting for answers. Toxicology UK helps Coroners have confidence that every reasonable question has been asked, every appropriate avenue has been explored and every conclusion is grounded in sound science. Its ability to deliver defensible answers and meaningful closure supports its recognition as Top Post-Mortem Toxicology Testing Solutions in UK 2026.
Selecting Post-Mortem Toxicology Testing that Can Stand Up to Uncertainty
An unexplained death investigation often starts with very little to go on. There may be no clear medical cause, limited information from the scene, no reliable witness account and no obvious physical explanation. That can leave the coroner or pathologist with a difficult question: did a substance play a role, or can toxicology help rule it out? Choosing a laboratory service therefore involves more than selecting a testing panel. The service needs to work effectively when important details are missing, without allowing that uncertainty to result in delays or inconclusive interpretation.
Drug-related deaths are also becoming more difficult to investigate. Routine screening remains important, but post-mortem testing increasingly has to deal with unfamiliar compounds, very low concentrations, prescription histories and combinations that fall outside established testing assumptions. Novel psychoactive substances make this particularly challenging because some can be highly potent at concentrations that are difficult to detect. Laboratories need broad screening capability and sufficiently sensitive detection methods, along with the expertise to recognize unusual chemistry and identify when targeted testing is necessary. Without that combination, a report may be technically accurate but still fail to answer the main question behind the investigation.

Turnaround time has consequences well beyond laboratory administration. Delays can postpone an inquest, extend uncertainty for families, complicate police decisions and slow the identification of emerging public health patterns that might otherwise be preventable. Speed alone, however, is not enough. Reporting that a substance is present without explaining what the finding means can leave the pathologist with another question to resolve. When assessing a provider, buyers should look at testing capacity alongside the scientific expertise available to interpret the results. A toxicology report is most useful when it arrives in time to narrow the possible explanations for a death.
Accreditation provides an essential foundation, but it does not tell the whole story. ISO credentials and established quality systems matter because toxicology evidence may face scrutiny long after the original analysis. What matters in practice is how those standards are applied through internal controls, external quality schemes, method validation and corrective action processes. Reporting requires the same care. The final report needs enough scientific reasoning to withstand expert review while explaining the findings in terms that coroners can use and understand outside the laboratory.
Interpretation is often the more difficult part of the work. Detecting and measuring a substance does not, by itself, establish its significance. The concentration has to be considered alongside the case history, possible tolerance, pathology findings and any other substances present. Post-mortem redistribution and gaps in the available background information can make that judgment more complicated. Adding more detail to a report does not necessarily make the answer clearer. What decision-makers need is a provider that can explain the significance of each finding without losing the uncertainty and context surrounding it, rather than leaving them to draw conclusions from concentration values alone.

Toxicology UK brings post-mortem toxicology testing and interpretation together within the same service model. Accredited analytical work is provided through NMS Labs, while UK-based toxicologists support case strategy, reporting, interpretation and HM Coroner inquests. This approach is suited to investigations where broad screening may need to be followed by targeted testing before the findings can be clearly explained. Its Toxicological Significance Score gives coroners a structured way to assess the likely relevance of each drug finding. The result is a service designed to provide more than an analytical result, giving coroners information they can use to understand what the toxicology findings mean within the context of the case.
