What Lextox does

Lextox is a Cardiff-headquartered, ISO 17025 UKAS-accredited laboratory (No. 7516) providing drug, alcohol, and DNA testing services to the UK family law sector. Founded in 2011 and wholly owned by the SYNLAB Group (part of Eurofins) since August 2017, the company serves over 17,000 solicitors, social workers, and local authorities involved in child care proceedings, custody disputes, and child protection cases. The core testing portfolio spans hair strand analysis (drugs, EtPa/EtG alcohol markers, month-by-month segmental reads up to 12+ months), blood alcohol biomarkers (PEth, LFT, CDT), nail testing, DrugPatch sweat monitoring, Breath Test with AFI facial recognition, SCRAM Continuous Alcohol Monitoring ankle bracelets, and a full suite of court-admissible DNA relationship tests (paternity, maternity, prenatal, sibling, grandparentage, avuncular, immigration). A reporting team with 150+ combined years of forensic toxicology experience issues expert reports and provides court witness testimony.

Underlying technology is grounded in accredited laboratory methods rather than software platforms: LC-MS/MS (Liquid Chromatography-Tandem Mass Spectrometry) for drug and metabolite quantification, cut-offs aligned with the Society of Hair Testing (SoHT), strict chain-of-custody procedures, and physical monitoring hardware (SCRAM bracelets, DrugPatch sweat patches, AFI facial-recognition breath devices). Lextox operates a nationwide UK collection network enabling sample collection within 24–48 hours and delivers analysis results with an average turnaround of four working days.

The business model is professional/managed services, fee-for-service, with bespoke per-case quotations issued by dedicated regional client managers rather than published price lists. Revenue streams include one-off toxicology and DNA testing, structured 30/60/90-day abstinence monitoring programmes (DrugPatch, Breath Test, SCRAM), expert reports bundled into case quotes, and complimentary CPD seminars used as demand generation into the legal professional community. The primary go-to-market is enterprise field sales through regionally-assigned client managers covering all UK jurisdictions, supported by CPD seminars, a Knowledge Hub of educational content, LinkedIn presence, and YouTube/webinar channels. Legal aid funding is accepted, and distribution for international immigration DNA testing is provided via sister laboratory Cellmark's 50+ country collection network.

Revenue model

1. Drug and Alcohol Testing Services: Lextox generates revenue primarily through fee-for-service testing across its range of toxicology services. Services are priced per test/case, with pricing provided via bespoke quotes from client managers. The company handles the full process from collection to analysis to final report delivery as a managed service. Testing types include hair drug and alcohol testing, blood alcohol testing (PEth, LFT, CDT), nail drug and alcohol testing, SCRAM continuous alcohol monitoring, DrugPatch monitoring, and breath alcohol monitoring. DNA testing is delivered through an accredited partner laboratory with pricing included in quotes.
2. Expert Reports and Court Witness Services: Lextox issues expert reports as part of the testing service, providing interpretation of analysis results for court proceedings. For child protection cases, expert reports are included as standard as results are more complex and require full interpretation. Court attendance for oral evidence is available upon request. Pricing for expert reports is incorporated into the overall case quotation rather than charged separately.
3. Abstinence Monitoring Programmes: Ongoing abstinence monitoring programmes using DrugPatch, Breath Test, or SCRAM bracelets are offered as managed service programmes, typically structured over 30, 60, or 90-day periods. Pricing covers the full programme including devices, regular sample collections/analysis, reporting, and dedicated client manager oversight throughout the programme.
4. CPD Seminars and Training: Lextox delivers complimentary CPD (Continuing Professional Development) seminars to legal professionals on 'Determining Parental Substance Use', covering hair drug and alcohol testing science, detection periods, sample collections, and reporting. While seminars are complimentary, they serve as a GTM and relationship-building tool that generates new client instructions and drives testing volume.
