Accredited Drug Testing provides extensive hair follicle drug analyses in Bray, California. For those requiring a hair drug or alcohol test, Accredited Drug Testing is a leader in this field with locations in cities across the country capable of conducting hair tests. You must have 1.5 to 2 inches of hair from your crown or body for testing. Hair analyses can detect drugs, alcohol/ETG, or other personalized testing options.
Recently, hair follicle drug testing has become a more common method for testing substances. A growing number of employers, courts, and substance abuse experts are favoring hair drug tests over traditional urine tests. Hair follicle tests are utilized by employers enforcing strict drug-free policies, courts, and individuals on probation. A key advantage of hair follicle drug testing is its extended detection period, reaching up to 90 days, while being nearly impossible to tamper with. However, for tracking drug use within the last 5 days, the urine test remains the most accurate.

Hair testing has emerged as an effective means for identifying drug and alcohol use. It provides a comprehensive historical record by capturing biomarkers embedded within the fibers of the growing hair. When collected near the scalp, hair samples can reveal up to a three-month detection timeline for alcohol and drugs. The collection process is straightforward, resistant to tampering, and easy to transport.
A 1.5-inch section of approximately 200 hair strands (comparable to a #2 pencil in width) near the scalp yields around 100mg of hair, optimal for screening and confirmation. For EtG, additional assessments, or panels exceeding 10, a specimen quantity of 150mg is advisable. Use a jeweler’s scale for measuring the sample weight. If scalp hair isn't accessible, a comparable amount of body hair can be used. "Head hair" refers exclusively to scalp hair, whereas "body hair" encompasses all other types (such as facial or axillary hair).
Process Overview
The laboratory processing of a drug test result involves four core steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase of processing a sample within a lab’s system. This step ensures the sample's proper sealing and shipping, assigns a random Laboratory Accessioning Number (LAN), and completes any additional data entry not covered by an electronic chain of custody system.
Screening provides a rapid initial assessment for drugs of abuse. Although a cost-efficient method to exclude drug usage in most samples, positive results from Screening require confirmation for legal admissibility. Presumptive positives in Screening necessitate further confirmation.
For presumptive positives detected during Screening, additional hair from the original specimen is retrieved for Extraction. Here, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), contributing to the complexity of hair drug screening.
Positive screening results are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. Samples that are presumptively positive undergo requisite washing prior to confirmation. The entire laboratory sequence, from Accessioning to Confirmation, undergoes scrutiny under CAP (College of American Pathologists) Hair designation standards and ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Often labeled as "hair follicle tests", this test examines the hair strand, not the scalp-embedded hair 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. 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.
