Offering comprehensive hair follicle testing, Accredited Drug Testing stands ready to meet your requirements in Montreal, Missouri. Our proficiency in hair drug and alcohol tests is matched by our extensive network of testing centers nationwide. Typically, at least 1.5 to 2 inches of hair is needed, whether from the scalp or body, to conduct precise drug, alcohol/ETG, or custom hair analyses.
Recently, hair follicle tests have gained traction as a standard method in drug testing. Employers, judicial systems, and Substance Abuse professionals prefer hair drug tests over urine tests. Employers with strict anti-drug policies, courts, and probation services greatly benefit from hair tests due to their 90-day detection window. Though unbeatable for long-term usage insights, urine tests still best capture recent drug use within five days.

Hair analysis has evolved into a significant method for identifying drug and alcohol consumption. Hair serves as an extensive archive of alcohol and drugs by embedding biomarkers within the fibers of the developing hair shaft. When sourced near the scalp, hair can reveal up to a nearly three-month period of detectability for alcohol and drugs. Hair collection is straightforward, relatively tamper-resistant, and easy for transportation.
A 1.5-inch segment of roughly 200 hair strands (comparable to a #2 pencil in thickness) near the scalp will yield 100mg of hair, which is the optimal sample for both screening and validation. For EtG assessments, additional tests, or screenings surpassing 10 panels, 150mg of the specimen is advisable. We suggest measuring the specimen using a jeweler’s scale. If scalp hair is inaccessible, a comparable amount of body hair can be utilized. The term head hair specifically denotes scalp hair, while body hair encompasses all other varieties (facial, axillary, etc.).
Procedure Summary
The key stages in laboratory analysis for a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary handling of a sample within a laboratory's infrastructure. This process includes confirming proper seal and shipment of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data entry absent from an electronic chain of custody system.
Screening executes an initial rapid assessment for drug substances. While a cost-effective strategy to exclude drug presence in most samples, a positive screen must be confirmed for court admissibility. Any samples with a presumptive positive in Screening necessitate additional confirmation.
Should a sample show presumptive positivity during Screening, extra hair from the initial sample is extracted and set for further Extraction. Here, drugs are isolated from hair in notably lower concentrations than other techniques (e.g., urine or oral fluid), highlighting why hair drug testing is a challenging process.
Confirmation of any positive screening is administered using GC/MS, GC/MS/MS, or LC/MS/MS methods. All presumptive positive samples undergo washing before confirmation as required. The comprehensive lab procedure, from Accessioning to Confirmation, is evaluated according to both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Note: Although commonly called "hair follicle tests", the test evaluates the hair strand and not the follicle beneath the scalp.

Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols. Manuscripts in this section present advancements in forensic toxicology, and have explored the challenges posed by emerging designer drugs and strategies to combat their proliferation. The pitfalls encountered when the exogenous/endogenous nature of a substance is questioned were presented and discussed. The special issue presents also manuscripts that delve into the ethical implications of drug testing in drug facilitated sexual assaults.
Clinical Applications of hair testing are witnessed by the insight on environmental tobacco smoke exposure, assessed by hair analysis in a population of students and the study of in utero-exposure to drugs of abuse through neonatal hair analysis. Exposure to drugs was also important in cases of child abuse/neglect, when the clinical purpose of hair testing merge with its forensic applications.
The legal framework surrounding hair testing and the achievement of guidelines to ensure fairness, accuracy, and confidentiality in drug testing practices have also been discussed,and the SoHT consensus on general hair testing and testing for drugs of abuse was presented at the meeting and published as a Letter to the Editor.
In conclusion, the special issue of Drug Testing and Analysis, featuring manuscripts from the SoHT–GTFI meeting in Verona 2022, reflects the remarkable advancements achieved in this field. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations.
