Accredited Drug Testing provides extensive hair follicle drug assessments in Johnson City, Texas. Whether you need a hair drug or alcohol evaluation, we specialize in hair testing and have facilities in all cities nationwide to facilitate your test. Typically, a length of 1.5 to 2 inches of hair from the crown or body suffices. These tests check for drugs, alcohol/ETG, or offer tailored testing solutions.
Over the years, drug testing methods have increasingly leaned towards hair follicle drug tests. Employers, judicial systems, and Substance Abuse professionals now favor hair over urine tests. Used by organizations with strict no-drug policies, courts, and probation services, hair follicle tests identify drug use over extended periods, up to 90 days. However, for detecting recent drug use, within 5 days, urine tests remain the most precise option.

The detection of drug and alcohol ingestion through hair testing is increasingly regarded as an effective approach. Hair records a comprehensive history of substance use, capturing biomarkers within the strands of developing hair. When collected near the scalp, hair provides an extended detection period of up to three months for alcohol and drugs. It's straightforward to collect, resistant to tampering, and convenient to transport.
Gathering a segment of hair approximately 1.5 inches in length, containing around 200 strands (similar in size to a #2 pencil), yields 100mg of hair, which is the optimal quantity for analysis and verification. For EtG, supplementary tests, and/or tests exceeding 10 panels, 150mg of the sample is suggested. It’s advised to measure the sample on a jeweler’s scale. If head hair is not accessible, an equivalent amount of body hair may be used. 'Head hair' refers solely to scalp hair, whereas 'body hair' encompasses all other types of hair (including facial, axillary, etc.).
Process Overview
The laboratory analysis of a drug test encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary integration of a sample into a laboratory’s framework. This step includes verifying the integrity and proper shipment of the sample, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry absent from an electronic chain of custody system.
Screening is a preliminary assessment to identify potential drug usage. Though Screening efficiently rules out drug use in most cases, a positive result requires confirmation to be valid in a legal context. Samples that are tentatively positive in Screening necessitate additional confirmation.
For samples tentatively positive in the Screening stage, extra hair is extracted from the initial sample for the Extraction phase. During this phase, drugs are isolated from hair at concentrations significantly lower than those in other sample types (e.g., urine or oral fluid), making hair drug screening the most challenging to execute.
Positive Screening results undergo confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleaned before confirmation if necessary. The comprehensive laboratory procedure, from Accessioning to Confirmation, is evaluated based on the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.

Note: The term "hair follicle tests" is frequently used, but the assessment targets the hair strand, not the hair follicle beneath the scalp

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.
