In Karns, Tennessee, Accredited Drug Testing offers comprehensive hair follicle drug testing services. If a hair drug or alcohol test is needed, Accredited Drug Testing is a specialist in this field, with numerous testing centers nationwide capable of conducting such tests. Usually, 1.5 to 2 inches of hair from the crown of the head or the body is required. Hair tests can be customized to detect drugs, alcohol/ETG, or other substances.
Recently, hair follicle drug tests have become more common in drug testing protocols. Many employers, legal authorities, and substance abuse specialists now prefer hair testing over the standard urine test. This is particularly true for employers with strict drug-free policies, courts, and individuals on probation. The significant advantage of hair follicle tests is their extended detection time for drug use—up to 90 days—alongside the secure collection process, making it nearly impossible to cheat. However, urine tests remain more accurate for identifying recent drug use within the last five days.

Hair analysis has emerged as a significant method for detecting substance and alcohol ingestion. Hair offers a prolonged timeline of alcohol and substance exposure by encapsulating biomarkers within the strands of hair as they grow. When procured near the scalp, hair can reveal an estimated 3-month timeframe for identifying alcohol and drug usage. Hair is straightforward to gather, relatively resistant to tampering, and simple to transport.
A 1.5-inch section comprising roughly 200 hair strands (about the width of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal sample for evaluation and validation. For EtG, additional examinations, and/or analyses exceeding 10 panels, 150mg of the specimen is advisable. Utilizing a jeweler’s scale for weighing the sample is suggested. If scalp hair is not an option, a comparable quantity of body hair can be collected. When mentioning head hair, it specifically denotes scalp hair only. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory approach to processing a drug test result encapsulates four critical phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the introductory handling of a sample into the laboratory’s system. This step includes verifying that the sample was correctly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent in an electronic chain of custody system.
Screening comprises an initial rapid assessment for illicit substances. Although Screening provides a cost-efficient method for dismissing substance use in the majority of samples, a positive screening needs confirmation to be legally valid. Any samples presumptively positive in Screening require a confirmatory analysis.
If a specimen is detected as positive during the Screening phase, additional hair is collected from the initial sample and prepared for Extraction. During this phase, substances are extracted from hair at much lower concentrations than other testing methods (e.g., urine or oral fluid), which makes hair drug testing a challenging process.
Confirmation of any positive screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive specimens are cleaned before confirmation as required. The comprehensive laboratory operation from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

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.
