In Clarksville, Tennessee, Accredited Drug Testing offers comprehensive hair follicle drug screening. Their expertise encompasses hair tests for both drug and alcohol detection, with centers accessible nationwide. Generally, having 1.5 to 2 inches of hair on the head or body suffices. Hair analysis can detect drugs, alcohol/ETG, and support various specialized testing options.
The trend of employing hair follicle drug testing has risen among employers, courts, and Substance Abuse professionals. This method, preferred over standard urine tests, appeals to employers enforcing zero-tolerance policies, probation systems, and judicial entities. Hair tests provide the advantage of a lengthy, near 90-day detection timeframe, executed under direct observation, and remain highly tamper-proof. However, urine tests retain accuracy for recent, within five-day drug use detection.

Hair analysis is now recognized as an influential method for monitoring drug and alcohol consumption. Hair captures a lasting record of alcohol and various drugs by embedding biomarkers within the strands of hair as it grows. Obtaining hair specimens near the scalp allows for identifying alcohol and drug use within a roughly 3-month period. Hair collection is uncomplicated, challenging to tamper with, and simple to transport.
A sample measuring 1.5 inches, comprising approximately 200 strands (about the dimension of a standard #2 pencil) closest to the scalp, provides 100mg of hair, which is the preferred amount for testing. For EtG additions or tests exceeding 10 panels, it's advised to use 150mg. Using a jeweler’s scale for weighing the hair specimen is suggested. If scalp hair isn't accessible, a similar amount of body hair can be gathered. When discussing head hair, it references only scalp hair, while body hair refers to all other types (facial, underarm, etc.).
Process Overview
The lab handling of drug test outcomes involves four crucial phases: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is entered into the laboratory’s system. This step includes ensuring proper sealing and shipping of the sample, assigning it a unique LAN (Laboratory Accessioning Number), and completing any missing data from an electronic chain of custody system.
Screening is a preliminary examination for signs of drug use. Although screening is an economical approach for ruling out drug usage in most cases, any positive results must be verified to be legally acceptable. Samples yielding a presumptive positive in screening demand further validation.
Should a sample indicate positivity in the Screening phase, additional hair is utilized from the initial batch for Extraction. In this process, drugs are retrieved from hair at lower concentrations than in other practices (e.g., urine or oral fluid), contributing to hair drug testing's complexity.
Any positive screening outcomes are validated through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo washing before confirmation as required. The comprehensive lab procedure from Accessioning to Confirmation is audited following both the CAP (College of American Pathologists) Hair certification and ISO / IEC 17025 accreditation.

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.
