Accredited Drug Testing provides thorough hair follicle drug assessments in Loudon, Tennessee. For those requiring a hair alcohol or drug evaluation, our expertise lies in these specialized tests, with centers across all cities nationwide capable of conducting hair analysis. Usually, a 1.5 to 2-inch segment from the crown or body is required. These tests can screen for drugs, alcohol/ETG, or other tailored testing options.
Recently, the preference for hair follicle drug checks has been on the rise. Increasingly, employers, courts, and substance abuse experts mandate these over standard urine checks. They are favored by institutions with zero-tolerance policies and for individuals on probation. The chief advantage is their extended detection time, up to 90 days, collected under supervision, making cheating nearly impossible. However, for recent use within five days, urine remains supreme.

Hair analysis has evolved into a robust method for identifying drug and alcohol consumption. The hair stores a lengthy record of substances by encapsulating biomarkers within the strands as they grow. When collected near the scalp, it offers roughly a 90-day period for detecting drugs and alcohol usage. Collecting hair is straightforward, relatively resistant to tampering, and simple to transport.
A segment of hair measuring 1.5 inches, comprising approximately 200 strands (comparable to a #2 pencil), is collected nearest the scalp to yield 100mg—the preferred quantity for screening and confirmatory analysis. For EtG, additional testing, and/or panel tests exceeding ten, a 150mg sample of hair is advised. It is recommended that the sample be weighed on a jeweler’s scale. In the absence of scalp hair, an equivalent measure of body hair may be used. Mention of head hair pertains specifically to scalp hair, while body hair encompasses all other forms (e.g., facial, axillary).
Procedure Summary
The laboratory process for analyzing a drug test sample traditionally includes four stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning signifies the initial inclusion of a sample into the laboratory framework. Steps include verifying proper sealing and shipping of the sample, issuing an arbitrary LAN (Laboratory Accessioning Number), and completing any extra data inputs not provided through a digital chain of custody system.
Screening entails an early appraisal for drugs of misuse. While Screening serves as an economical means for excluding drug use in most cases, a positive result mandates verification to be legally valid. Presumptive positives from Screening must undergo additional confirmation.
Should a sample test presumptively positive during Screening, further hair is extracted from the specimen for preparation in the Extraction phase. Here, drugs are isolated from hair at concentrations lower than other methods (e.g., urine or oral fluid), thus highlighting the complexity of hair drug testing.
Any positive screens receive Confirmation through GC/MS, GC/MS/MS or LC/MS/MS. Preceding Confirmation, all presumptive positive samples undergo washing as required. The entire lab sequence, from Accessioning to Confirmation, adheres to the CAP (College of American Pathologists) Hair guidelines, alongside ISO / IEC 17025 standards.

Challenges:
Note: While commonly termed "hair follicle tests", the procedure examines the hair strand itself, 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.
