Accredited Drug Testing provides comprehensive hair follicle drug testing in Sherman, Texas. For hair drug or alcohol tests, we focus on hair testing and maintain testing centers in cities nationwide capable of performing such tests. Generally, 1.5 to 2 inches of hair on the head or body are required for analysis. Hair tests can detect drugs, alcohol/ETG, or be customized for specific testing needs.
Recently, drug testing approaches have increasingly incorporated hair follicle drug tests. Numerous employers, judicial systems, and substance abuse professionals prefer hair tests over traditional urine tests. These tests are employed by drug-free employers, courts, and probation officers due to their extended detection period of up to 90 days, monitored collection process, and difficulty in manipulation. However, for identifying recent drug use within five days, urine tests remain most accurate.

Hair testing has gained recognition as a robust method for identifying alcohol and drug use. Hair retains a prolonged record of substance consumption by encapsulating biomarkers within the growing hair fiber. When sourced near the scalp, it can offer a detection span of up to roughly three months for alcohol and substances. The collection of hair is straightforward, relatively resistant to tampering, and convenient for transportation.
A hair sample measuring 1.5 inches, consisting of approximately 200 strands (comparable to a #2 pencil), will yield 100mg, which is optimal for testing and validation. For EtG, additional analyses, and/or panels exceeding ten, a 150mg sample is advisable. Using a jeweler’s scale for specimen measurement is suggested. If scalp hair is not available, a comparable quantity of body hair is suitable. "Head hair" refers exclusively to scalp hair, whereas "body hair" encompasses all other types (such as facial or axillary).
Process Overview
The principal stages in laboratory drug test processing include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where the sample is introduced into the laboratory's records. This process verifies the sample's sealing and proper shipping, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry not handled by an electronic chain of custody system.
Screening offers a preliminary evaluation for drug presence. Despite its cost-efficiency for eliminating drug use in most samples, a positive screen must be confirmed for legal acceptability. Samples testing presumptively positive in Screening necessitate further confirmation.
Upon a presumptively positive Screening outcome, more hair is extracted from the original sample for Extraction. During Extraction, drugs are retrieved from hair at notably lower concentrations compared to alternatives (like urine or saliva), underscoring the complexity of hair drug testing.
Any positive screening result undergoes Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Prior to confirmation, presumptive positive samples are cleansed as required. The comprehensive laboratory workflow, from Accessioning to Confirmation, is supervised under the CAP (College of American Pathologists) Hair criteria and is accredited 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.
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. As we embrace these advancements, we pave the way for a safer, healthier society, where drug testing and analysis serve as powerful tools in protecting public health and maintaining integrity in various sectors. The research presented in this special issue will undoubtedly shape the future of drug testing and analysis, fostering collaboration and inspiring further innovation in this crucial area of scientific inquiry.
