4N6 and its laboratory partners provide international forensic laboratory services over several analytical fields. All our business units are accredited to international forensic standards from which our scientists produce high quality investigative findings for our partners. Our aim is to provide a cost effective, fast and valued service which can be tailor made to fit individual needs. We operate as a world leader in our field and have partners in all parts of the world. For further information on all our services please contact our business development team.
Service areas include:

DNA Profiling
We can process DNA samples and generate confirmatory results using most internationally used forensic marker systems and analysis methods including; UK (SGM+ STR kit), USA (CODIS STR marker), Germany (DAD STR marker). Our laboratory handles extended STR marker sets in paternity cases and also has vast experience in LCN analyses. Other expertise areas include various Y-STR marker systems and mitochondrial DNA.

Forensic Toxicology
4N6 provides toxicology services in association with our partners covering both ante-mortem and post mortem investigations. Using a variety of analytical techniques including gas chromatography - mass spectrometry (GS - MC) we can provide investigative solutions on a bespoke basis to fit the needs of individual cases. Our testing services can facilitate a large array of sample types including body fluids, hairs and other substances including nails to confirm the presence of compounds such as:

• Therapeutic drugs
• Drugs of abuse
• Alcohol
• Solvents
• Poisons
• Carbon monoxide (required for fire related deaths).

Isotope testing - Isotrace
Continuous Flow Isotope Ratio Mass Spectrometry (CF-IRMS) is a powerful forensic technique using signals recorded by living organisms such as human beings or plants. As a result, we have been assisting several UK law enforcement agencies by providing valuable intelligence based on stable isotope fingerprinting of human tissue on geographic origin and life history of murder victims and unidentified persons. Our lab team also uses Isotrace within toxicology for the identification of unknown substances such as illicit drugs. For more information contact our business development team.
