Located in Bellville, Texas, Accredited Drug Testing offers comprehensive hair follicle drug analyses. If a hair or alcohol screening is necessary, Accredited Drug Testing specializes in these procedures and provides testing facilities across all Nationwide cities. A minimum of 1.5 to 2 inches of head or body hair is generally required. Tests can identify drug, alcohol/ETG, and other tailored options available upon request.
In the past few years, hair follicle drug tests have become a more common choice for drug screening. They are often requested by employers, legal systems, and substance abuse professionals over the standard urine tests. Hair follicle tests are preferred due to their extended detection period of up to 90 days, almost impossible to bypass, and conducted under direct supervision. Nevertheless, for drug use within the last 5 days, urine tests remain the most precise.

Hair analysis is now recognized as an effective means to uncover drug and alcohol consumption. Hair offers an extended history of alcohol and drug usage by capturing biomarkers within the strands' fibers. When taken near the scalp, it presents nearly a 90-day detection window for drugs and alcohol. The collection process is straightforward, manipulation is challenging, and transportation is effortless.
A sample measuring 1.5 inches, with roughly 200 hair strands (comparable to the girth of a #2 pencil), located closest to the scalp, supplies 100mg of hair—ideal for screening and validation. For enhanced tests like EtG or panels exceeding 10, a 150mg sample is better suited. Using a jeweler’s scale is advised for measuring the sample. In cases where scalp hair isn't available, an equivalent amount of body hair can be obtained. When mentioning head hair, it pertains solely to scalp hair, whereas body hair pertains to all alternative hair types (such as facial and axillary).
Process Overview
The four principal stages in processing a lab drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary processing of a specimen into a laboratory's framework, entailing verification of proper sealing and shipping, assignment of a random LAN (Laboratory Accessioning Number), and completing any extra data entry not covered through an electronic custody chain system.
Screening is an initial quick assessment for substances of abuse. Though cost-effective for eliminating drug use in most samples, positive findings require confirmation for court admissibility. Presumptive positives in Screening need a follow-up confirmation.
If Screening suggests a positive outcome, additional hair is extracted from the primary specimen and prepped for Extraction. Here, drugs are extricated from hair at significantly reduced concentrations compared to other methods like urine or oral fluids, highlighting the complexity of hair drug evaluation procedures.
Confirmation of positive screenings follows through GC/MS, GC/MS/MS, or LC/MS/MS. Samples with preliminary positive results undergo washing before confirmation if necessary. The complete lab process from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Note: Commonly dubbed as "hair follicle tests", the assessment examines the hair strand instead of the under-scalp follicle.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.
It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. 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.
In conclusion, the special issue of Drug Testing and Analysis, featuring manuscripts from the SoHT–GTFI meeting in Verona 2022, reflects the remarkable advancements achieved in this field. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations.
