Offering comprehensive hair follicle drug testing in Woodstock, Virginia, Accredited Drug Testing is your go-to for hair and alcohol tests. Specializing in hair analysis, our centers are nationwide, available in every city to facilitate your testing needs. Typically, a hair length of 1.5-2 inches from the crown or body is required. Our tests detect drugs, alcohol/ETG, and offer custom hair testing solutions.
Recently, the prevalence of hair follicle drug testing has increased, surpassing traditional methods. Many employers, judiciary systems, and substance abuse counselors opt for hair tests instead of routine urine analysis. Hair tests cater to zero-tolerance policies, judicial requirements, and probation cases, offering up to 90 days of drug use tracking through an observed process that's difficult to bypass. However, for detection within a 5-day window, urine tests remain effective.

Hair analysis has become recognized as a vital resource in identifying substance and alcohol consumption. Hair captures a prolonged timeline of alcohol and drug use by embedding biomarkers within the structure of the emergent hair strand. When gathered near the scalp, hair can offer an approximate 3-month detection scope for substances like alcohol and other drugs. Hair collection is straightforward, relatively hard to tamper with, and simple to transport.
A sample length of 1.5 inches, approximately 200 hair strands (about the thickness of a #2 pencil) nearest to the scalp, yields 100mg of hair, the optimal sample size for analysis and validation. For EtG, additional tests, and/or panels exceeding 10, a 150mg sample is preferred. We advocate using a jeweler’s scale for weighing the sample. If head hair is inaccessible, a comparable amount of body hair can be collected. By head hair, we specifically mean scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
An Overview of the Process
The principal phases in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the preliminary handling of a sample into a lab’s workflow. This process comprises verifying sample integrity for sealing and shipping, generating a random LAN (Laboratory Accessioning Number), and finalizing any pending data entry not already covered by an electronic chain of custody document.
Screening refers to an initial rapid assay for identifying drug abuse. While Screening is an economical method to eliminate drug consumption in most samples, a positive indication necessitates formal validation to be court-admissible. Any samples with a presumptive positive in Screening need further confirmation.
If a specimen shows a presumptive positive during Screening, additional hair is taken from the original sample for Extraction. In this phase, drugs are withdrawn from hair at concentrations much lower than other methods (ex. urine or oral fluid), making hair drug analysis the most intricate method to execute.
Validation of any presumptive positive result follows through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Every presumptive positive specimen is prepped by washing, as required, prior to confirmation. The complete lab process from Accessioning through Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair criteria and ISO/IEC 17025 accreditation 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.
