Forensic Biology Services
At Forensic Access, we provide specialist forensic biology services tailored to the needs of criminal defence solicitors and barristers. Forensic biology is commonly utilised across a wide range of case types from allegations of murder or sexual assault to possession of firearms or illegal substances. Our experienced forensic biologists support fair justice by offering clear and objective insights to inform the defence team’s decision making.
We go beyond analysis. We work with you to thoroughly test the prosecution’s evidence, evaluate the findings given the alternative explanations, and ensure every forensic opportunity is properly explored.
Our Forensic Biology Services:
All our scientists are highly experienced court going experts working within prosecution forensic service providers and delivering forensic services to the defence over many years. Forensic Access has the benefit of ISO/IEC 17025:2017 accredited laboratories where examinations can take place. Our forensic biologists offer a wide range of services, including:
Body Fluid Identification and Interpretation: Screen and test for a range of commonly encountered body fluids such as blood, saliva and semen. Assess the nature and distribution of any body fluids present to assist in evaluating how they may have been deposited.
Blood Pattern Analysis (BPA): Expert analysis of blood patterns on clothing, weapons or at scenes to aid in the overall evaluation of an incident.
DNA Recovery: Examine items and sampling for DNA profiling within our accredited laboratories.
DNA Interpretation & Review: Independent interpretation of DNA results – either following our own examinations, or a review into the work conducted by other laboratories. We assess the strength, context, and reliability of the findings.
Textile Damage Assessment: Evaluating damage features on clothing and other textiles to determine how they were generated and aid in the overall evaluation of the case.
Hair Analysis: Microscopic examination can identify the origin, show whether the hair was shed or forcibly removed, and determine suitability for DNA profiling.
Crime Scene Re-Examination: Full crime scene examination and re-examination, to conduct an independent evaluation and identify new opportunities. This can be conducted in situ or, where no longer possible, from scene images and videos.
Historic, Post-Conviction & Cold Case Reviews: Thorough review of forensic work previously conducted. Whether for current cases or historic investigations, our experts uncover issues, gaps, or potential new lines of enquiry.
Joint Expert Examinations: We offer a multidisciplinary approach by working closely with in-house experts in fingerprints, firearms, digital forensics and more. This collaboration ensures no opportunities are overlooked and all applicable tests are considered.
