In Saint Mary, Missouri, Accredited Drug Testing offers thorough hair follicle drug testing services. For those requiring a hair drug or alcohol test, our specialty centers nationwide are equipped to conduct these tests. Typically, 1.5 to 2 inches of hair from the head or body are needed. Hair tests can screen for drugs, alcohol/ETG, and other testing needs.
The use of hair follicle drug testing has surged in recent years. More employers, courts, and substance abuse experts now prefer it over urine tests. This test is favored by workplaces enforcing zero-tolerance policies, judicial systems, and probationary monitoring. One key advantage is its extended detection period of up to 90 days, observed in collection, making it nearly foolproof. However, urine tests remain optimal for detecting recent use within the last 5 days.

Hair testing is recognized as a potent method for identifying drug and alcohol usage. Hair retains a prolonged record of alcohol and drugs by capturing biomarkers within the structure of the growing hair strand. When obtained near the scalp, hair can deliver roughly a 3-month detection span for alcohol and drugs. The collection of hair is straightforward, comparatively tough to tamper with, and easy for transportation.
A 1.5-inch section comprising about 200 strands of hair (approximately the width of a #2 pencil) near the scalp provides 100mg of hair, which is the perfect sample quantity for screening and validation. For EtG, additional criteria, and/or analyses beyond 10 panels, a 150mg sample is advisable. It's suggested to use a jeweler’s scale for weighing the specimen. Should scalp hair be inaccessible, an equivalent sum of body hair can be collected. By head hair, we mean strictly scalp hair. The term body hair includes all other hair varieties (facial, axillary, etc.).
Process Overview
Four primary stages are implicated in the lab procedure of processing a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial handling of a specimen within a lab’s framework. This phase involves ensuring that the sample is sealed and dispatched correctly, allocating a random LAN (Laboratory Accessioning Number), and completing any remaining data entry absent in an electronic chain of custody framework.
Screening represents a preliminary fast review for illicit substances. Though Screening is an economical method for clearing drug usage for the majority of specimens, a positive outcome necessitates confirmation to stand up in legal settings. Samples showing presumptive positivity in Screening demand additional validation.
If a specimen exhibits presumptive positivity in the Screening phase, more hair is sourced from the original sample and set up for Extraction. In Extraction, substances are drawn from hair at markedly lower concentrations than in alternative approaches (e.g., urine or oral fluid), making hair drug screening a notably challenging procedure.
Affirmation of any positive screening result occurs through GC/MS, GC/MS/MS, or LC/MS/MS. Before validation, all presumptive positive samples undergo cleaning. The entire lab process from Accessioning to Confirmation is evaluated per both the CAP (College of American Pathologists) Hair distinction and the standards of accreditation to ISO / IEC 17025.

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.
