Accredited Drug Testing offers comprehensive hair follicle drug testing services in Victoria, Tennessee. For those in need of a hair drug or alcohol test, our specialism in hair testing is available through our centers located in all cities nationwide. Typically, 1.5 to 2 inches of hair from the scalp or body can be used. Our hair tests can identify drugs, alcohol/ETG, or other tailored testing solutions.
Over recent years, drug testing procedures increasingly incorporate hair follicle testing. Employers, judicial systems, and Substance Abuse experts often prefer hair tests over conventional urine ones. Hair follicle tests are favored by employers with strict anti-drug policies, courts, and probationers alike. The principal advantage is the extended detection period, often up to 90 days, obtained through an observed process, making it highly tamper-proof. Nevertheless, for detecting recent drug use within five days, urine testing remains superior.

Hair analysis is recognized as an effective means for identifying drug and alcohol consumption. Hair serves as a prolonged historical record by encapsulating biomarkers within its growing fibers. Samples obtained near the scalp can offer a detection period for alcohol and other drugs of roughly three months. Hair collection is straightforward, relatively resistant to tampering, and convenient to transport.
A sample size of 1.5 inches containing about 200 hair strands (comparable to the thickness of a #2 pencil) from near the scalp provides 100mg of hair, which is the optimal amount for testing. For the EtG test, additional panels, or tests exceeding 10-panel screening, a 150mg sample is advisable. It is suggested to weigh the sample using a jeweler's scale. In the absence of scalp hair, body hair may be utilized in equivalent amounts. The term head hair specifically refers to scalp hair alone. Body hair encompasses other types such as facial and axillary hair.
Process Overview
The key phases in laboratory processing for drug testing entail Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to inserting a sample into the laboratory's system. This step ensures the sample's proper sealing and shipment, assigns a random Laboratory Accessioning Number (LAN), and completes any necessary data entry not covered by an electronic chain of custody.
Screening provides an initial assessment for drug presence. This cost-effective approach can exclude drug use in most samples; however, any positive result requires confirmation for legal admissibility. Presumptive positives during Screening need further confirmation.
When Screening identifies a presumptive positive, additional hair is extracted from the primary sample for the Extraction phase. Drugs are retrieved from hair at lower concentrations than in other methods (e.g., urine or saliva), making hair drug testing particularly challenging.
Positive Screening results are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives undergo washing before Confirmation if necessary. The process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although called "hair follicle tests", the analysis actually examines 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.
