Alcohol Testing
Hair Strand Alcohol Testing for Court-Directed & Legal Proceedings
Hair strand alcohol testing forms part of Forensic Testing Service’s (FTS) court-directed alcohol testing services, supporting legal and safeguarding proceedings where understanding alcohol consumption over time is essential. It is commonly instructed by solicitors and local authorities in matters including family law and childcare cases, where decisions must be based on reliable, proportionate evidence.
Scalp hair strand testing for alcohol provides insight into alcohol use across an extended period and can assist the court in assessing patterns of consumption rather than isolated events. However, hair testing alone is not relied upon to reach conclusions. At FTS, alcohol assessment is approached as a forensic investigation combining multiple testing methods, not a screening exercise.
Results from all testing methods are interpreted together, alongside contextual information provided on each individual case, supporting decision-making based on a balance of probabilities. Throughout the process, FTS conducts an investigative, multi-method approach, placing a strong emphasis on accuracy and defensible interpretation.
What Is Hair Strand Alcohol Testing?
Hair strand alcohol testing involves the analysis of hair samples to detect specific alcohol biomarkers that become incorporated into hair as it grows. Rather than detecting alcohol itself, testing focuses on biomarkers associated with alcohol consumption within a specified period.
This method can provide insight into alcohol use across several months, depending on hair length and suitability. Hair alcohol testing is particularly useful where the court requires an overview of longer-term consumption patterns rather than evidence of a single episode of drinking.
Hair strand testing is therefore used as one component of a broader alcohol assessment and is not designed to assess immediate or very recent alcohol use.
How FTS Supports Your Case
Dedicated Case Management and Legal Support
Each alcohol testing case is supported by a dedicated FTS case manager who acts as a consistent point of contact throughout the process. Case managers provide procedural guidance on appropriate testing profiles and help ensure testing remains proportionate to the issues under consideration.
Costs are aligned with Legal Aid Agency codified rates. Support is also available for practical matters such as example Part 25 applications and court order wording. This support is procedural in nature and does not constitute legal advice.
Comprehensive Client Questionnaire
Every alcohol case undertaken by FTS includes a detailed client questionnaire. This forms a critical part of the forensic assessment and supports accurate interpretation of numerical results.
The questionnaire covers alcohol use over the previous 12 months and includes all known factors that could influence test results. It is one of the most detailed questionnaires in the industry and is essential for ensuring balanced, evidence-led conclusions.
This process helps guard against over-simplification of results and supports fairness in cases where the interpretations carry significant legal weight.
Instruction and Sample Collection
Alcohol testing can be instructed via an online form, PDF instruction or by contacting the FTS customer service team directly. Sample collection is arranged by FTS and carried out by trained professionals.
A mobile collection service is available where required, with an emphasis on discretion, safety and robust chain of custody. This ensures continuity and evidential integrity from collection through to reporting.
Case Study Reference
FTS alcohol testing has supported a wide range of court-directed proceedings. Relevant alcohol testing case studies demonstrate how forensic interpretation has clarified complex alcohol use and assisted the court in reaching informed decisions. Full case studies are available separately.
The FTS Model of Best Practice
FTS does not rely on “positive” or “negative” results alone. Alcohol testing is approached as a forensic investigation designed to answer the specific questions being asked by the court.
Results are interpreted alongside contextual information, disclosure and case history. This approach is designed to meet the evidential standards required in legal proceedings and to support robust, defensible conclusions rather than over-simplified outcomes.
By applying alcohol testing within a structured forensic framework, FTS helps to ensure that evidence is explained thoroughly so that it may be used fairly and appropriately when making safeguarding decisions.
Why Hair Testing Alone Is Not Sufficient
Decisions with safeguarding implications should not rely on a single test. While hair alcohol testing can provide valuable information, it does not capture the full complexity of alcohol consumption on its own.
Strict reliance on hair testing or cut-off levels alone can lead to ambiguous interpretation or inaccurate conclusions, particularly where individual circumstances vary. Without context, results may be misunderstood or given inappropriate weight.
For this reason, contextual forensic analysis is essential where alcohol testing will inform court decisions. Hair testing must be considered alongside other evidence and testing methods to ensure balanced and proportionate outcomes.
FTS’s testing strategies are tailored to the questions being asked by the court, ensuring proportionality and responsible use of public funds.
A Multi-Method Testing Profile for Greater Accuracy
Wherever practically possible, FTS’s alcohol assessments include a combination of testing methods to address different evidential timeframes. Standard practise would include:
- Hair strand testing for alcohol biomarkers (EtG and EtPa) which are indicative of units consumed (covers months)
- Blood testing for PEth which are indicative of units consumed (covers weeks)
- Blood testing for relevant liver function markers (MCV, CDT, GGT-CDTr and LFT) (covers weeks)
- Nail testing can also be instructed alongside, or instead of hair strand testing.
Using a single testing method alone cannot usually provide the level of clarity required in legal proceedings. A combined approach allows differentiation between excessive consumption, reduced use and other explanations that may affect results.

News & Insights
What Our Customers Say
FAQ
Is hair alcohol testing court-approved?
Yes. Hair alcohol testing is widely accepted in court-directed and legal proceedings when conducted and interpreted appropriately.
Can hair strand testing for a single compound determine alcohol misuse?
No. Single-compound hair testing should not be relied upon in isolation and forms part of a wider forensic assessment.
Why does FTS use multiple alcohol testing methods?
Because no single test can provide a complete picture of alcohol use over time. Combined testing improves clarity and reduces ambiguity.
How far back can hair strand alcohol testing assess consumption?
This depends on hair length and suitability, but hair testing can provide insight into alcohol use over several months, depending on individual variance and hygiene routines.
Who typically instructs FTS for alcohol testing?
FTS is instructed by solicitors and local authorities supporting a wide range of court-directed and legal proceedings.
