Accredited Drug Testing provides comprehensive hair follicle drug testing services in Encinal, Texas. For those needing hair drug or alcohol tests, Accredited Drug Testing is a leader in this field, offering testing centers across the nation capable of conducting hair tests. Typically, 1.5 to 2 inches of hair from the crown or body is required. Hair tests can be customized to screen for drugs, alcohol/ETG, and more.
There's been a shift towards using hair follicle drug tests in recent years. Increasingly, employers, courts, and Substance Abuse experts prefer hair testing over traditional urine tests. This method is favored by employers with strict no-drug use policies, legal systems, and probation services. A major advantage of hair follicle tests is their extended detection period for drugs, reaching up to 90 days, and the fact that they are collected under observation, making them difficult to tamper with. However, for detecting recent drug use within the last 5 days, urine tests remain the most precise.

Hair analysis has emerged as an effective means of detecting drug and alcohol consumption. By capturing biomarkers within the fibers of the growing hair shaft, hair offers a comprehensive track record of alcohol and drug use. When gathered near the scalp, hair can reveal a detection span of up to roughly three months for alcohol and drugs. Hair collection is straightforward, relatively hard to tamper with, and convenient to transport.
A hair sample of 1.5 inches, comprising around 200 strands (comparable to the circumference of a #2 pencil) nearest to the scalp, yields 100mg, ideal for analysis and verification. For EtG enhancements and/or tests involving more than 10 panels, a 150mg sample is suggested. It is advisable to measure the sample using a jeweler’s scale. If scalp hair is inaccessible, an equivalent volume of body hair can be used. References to head hair solely imply scalp hair. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The laboratory handling of a drug test result encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary integration of a sample into the laboratory’s framework. It involves confirming that the sample was correctly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent in an electronic chain of custody system.
Screening provides an expedient preliminary assessment for drug presence. While Screening offers an economical method to exclude drug usage across most samples, a positive result requires validation to be considered legal evidence. Samples appearing presumptively positive during Screening necessitate further confirmation.
In cases where a sample is presumptively positive during Screening, additional hair is extracted from the main sample for Extraction. Here, drugs are isolated from hair at significantly lower concentrations than in other methods (e.g. urine or oral fluid), underscoring the complexity of hair drug screening methodologies.
Confirmation of positive screenings is conducted through GC/MS, GC/MS/MS, or LC/MS/MS, with all presumptive positive samples undergoing washing before confirmation if necessary. The laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

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.

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.
