Accredited Drug Testing offers comprehensive hair follicle drug testing services in Portland, Tennessee. For those needing a hair drug or alcohol test, we specialize in hair testing at numerous centers across the United States. Typically, 1.5 to 2 inches of hair from the crown or another body part is required. Hair samples can be examined for drugs, alcohol/ETG, or tailored testing criteria.
In recent years, drug testing methods increasingly include hair follicle tests. Employers, courts, and Substance Abuse professionals often prefer hair tests over traditional urine tests. Hair tests are chosen by employers with zero-tolerance policies, legal systems, and probation individuals. The main advantage is hair testing's extended detection window of up to 90 days, through an observed and tamper-resistant process, though urine tests remain the best for uncovering recent drug use within five days.

Hair testing has evolved into a significant method for detecting drug and alcohol consumption. Hair offers a prolonged history of substance use by capturing biomarkers within the fibers of the hair as it grows. Gathering hair near the scalp enables an approximate 3-month detection period for alcohol and drugs. Hair is straightforward to collect, somewhat challenging to adulterate, and convenient to transport.
A 1.5-inch sample consisting of around 200 hair strands (resembling the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample size for screening and validation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advised. It is suggested to measure the specimen using a jeweler’s scale. Should scalp hair be unavailable, an equivalent quantity of body hair can be sampled. When referencing head hair, it pertains strictly to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The lab processing of a drug test result entails four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the introductory phase of processing a sample within a lab’s system. This phase incorporates confirming that the sample was properly sealed and delivered, allocating a random LAN (Laboratory Accessioning Number), and concluding any supplementary data entry absent in an electronic chain of custody system.
Screening constitutes an initial rapid assessment for drug use. Though cost-effective for ruling out drug usage across most samples, a positive screening necessitates validation for court admissibility. Any samples flagged as potentially positive during Screening demand further confirmation.
Should a sample indicate potential positivity during Screening, additional hair is extracted from the initial sample for the Extraction stage. Here, drugs are extracted from hair at considerably lower concentrations than other methods (e.g., urine or oral fluid), underscoring the challenge of hair drug screening.
Confirmation for any positive screening outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as required. The comprehensive lab process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.

Limitations:
Note: Although often called "hair follicle tests", the analysis is conducted on the hair strand, not the follicle beneath the scalp.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.
It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. 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.
