For those needing a hair-based drug or alcohol analysis, we at Accredited Drug Testing are experts in this testing method, with facilities across all cities Nationwide ready to conduct the test. Typically, hair from the crown or body, approximately 1.5 to 2 inches long, is required.Hair assessments can evaluate for drugs, alcohol/ETG, or diverse testing customizations.
Hair follicle drug testing has been increasingly used in recent years as a method for drug analysis, commonly replacing the standard urine test by employers, judicial systems, and substance abuse experts. This testing method is recommended for organizations with no drug tolerance, courts, and probationary individuals. Its key benefit lies in its extensive detection timeframe, spanning up to 90 days, done through a monitored process, making tampering nearly impossible. Nevertheless, urine tests remain the most precise for recent drug use within a five-day range.

Hair analysis has increasingly gained recognition as an effective method for identifying drug and alcohol use. Hair can offer a comprehensive history of substance use by capturing biomarkers within the strands as they grow. When samples are taken near the scalp, hair can present a detection reach of up to about three months for alcohol and drugs. Collecting hair is straightforward, relatively hard to tamper with, and uncomplicated to transport.
A 1.5-inch selection of roughly 200 hair strands (similar to the thickness of a #2 pencil) from the scalp will yield 100mg of hair, the optimal amount for both screening and confirmation. For EtG, extended panels, or tests exceeding 10 panels, 150mg of the sample is suggested. It's advisable to weigh the sample using a jeweler’s scale. In cases where scalp hair is absent, an equivalent portion of body hair can be collected. By head hair, we mean only scalp hair, whereas body hair covers all other hair types (e.g., facial, axillary).
Process Overview
The four primary phases in the lab handling of a drug test are Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial intake of a sample into a lab’s system. This step involves ensuring the sample is properly sealed and shipped, assigning it a random LAN (Laboratory Accessioning Number), and completing any missing data entry not handled by an electronic chain of custody system.
Screening entails a preliminary check for drug presence. While it serves as a cost-effective method to identify drug use in most samples, a positive screening result necessitates confirmation to be permissible in legal settings. Samples showing presumptive positivity in Screening require a follow-up confirmation.
In cases of presumptive positive results during Screening, additional hair is extracted from the initial sample for Extraction. In this phase, drugs are extracted from hair at considerably lower concentrations compared to alternative methods (e.g., urine or saliva), highlighting why hair testing is among the most complex methodologies.
Confirmations of positive screening outcomes are performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed before confirmation as necessary. The entire laboratory sequence from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair designation and is accredited to ISO / IEC 17025 standards.

Limitations:
Note: Though often termed as "hair follicle tests", the examinations target the hair strand, not the follicle beneath the scalp.

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.
