Specializing in hair drug and alcohol testing, we have centers in cities nationwide, ready to conduct hair tests. Generally, 1.5 to 2 inches of hair from the crown or body is utilized. Hair tests detect drugs, alcohol/ETG, or offer customized options.
Recently, hair follicle tests have been increasingly used for drug testing. Employers, courts, and substance abuse experts often prefer hair tests to urine tests, due to zero-tolerance policies, legal requirements, or probation. Hair follicle testing offers an extended 90-day detection window, includes observed collection, and is hard to cheat. However, for drug screening within 5 days, urine tests remain most accurate.

Hair testing is now recognized as an effective means for identifying drug and alcohol usage. By capturing biomarkers within the fibers of the growing hair strand, hair offers a comprehensive history of alcohol and other drugs. When collected near the scalp, it can provide a detection period of up to roughly 3 months for alcohol and other drugs. Hair collection is straightforward, hard to tamper with, and simple to ship.
A sample measuring 1.5 inches with roughly 200 hair strands (about the diameter of a #2 pencil) nearest to the scalp yields 100mg, which is the optimal amount for both screening and confirmation. For EtG, additional tests, and/or those exceeding 10 panels, 150mg of the sample is advisable. Assessing the specimen's weight using a jeweler’s scale is suggested. If scalp hair is unavailable, an equivalent amount of body hair may be utilized. In reference to head hair, it pertains exclusively to scalp hair. Body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
The procedure for processing a drug test at the lab consists of four essential stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab’s system. It involves confirming proper sealing and dispatch of the sample, allocating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.
Screening initiates a preliminary swift examination for drugs of abuse. While Screening is an economical approach to exclude drug usage in the majority of samples, a positive result necessitates confirmation for legal acceptance. Samples indicating presumptive positivity in Screening require further confirmation.
If Screening suggests a presumptive positive, additional hair is drawn from the original sample and readied for Extraction. At this phase, drugs are extracted from hair at a considerably lesser concentration than other methods (ex. urine or oral fluid), highlighting why hair drug screening is among the most challenging methodologies.
Confirming any positive Screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples are cleansed as required. From Accessioning to Confirmation, the complete process is vetted under both CAP (College of American Pathologists) Hair standards and the 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.
