Accredited Drug Testing provides comprehensive hair follicle substance analysis in Arden Town, California. For those requiring hair-based drug or alcohol screenings, we are experts with facilities across the nation ready to conduct these tests. Typically, 1.5 to 2 inches of head or body hair is required for effective testing. Hair analyses can screen for drugs, alcohol/ETG, or other tailored assessments.
Recently, hair follicle analysis has gained preference in drug screening techniques. A growing number of employers, judicial systems, and addiction specialists now favor hair tests over traditional urine tests. Hair follicle tests are particularly beneficial for strict no-drug-use environments, legal settings, and probation management. The key advantage is their extended detection window, revealing drug use within a 90-day period, and ensuring integrity through observed collection, making cheating nearly impossible. However, for recent drug use within the past 5 days, urine tests remain the most effective.

When you're searching for hair drug testing near me or hair drug testing locations, we provide a simple and convenient process to find a drug and alcohol testing location near you that is certified to provide all of your drug and alcohol testing needs.
The evaluation of alcohol and drug use through hair testing has emerged as a robust method. By encapsulating biomarkers within the strands of growing hair, it offers a long-term history of substance use. When collected near the scalp, the hair can reveal alcohol and drug usage for up to roughly three months. The process is straightforward, challenging to tamper with, and easy to transport.
Gathering a 1.5-inch segment of around 200 hair strands (approximately the girth of a #2 pencil) near the scalp yields 100mg of hair, which is the optimal sample for both screening and verification. For EtG, additional testing, and/or panels exceeding 10, a specimen of 150mg is advised. It's suggested to weigh the sample using a jeweler’s scale. If scalp hair is not available, a comparable quantity of body hair can be obtained. In this context, head hair refers specifically to scalp hair, while body hair encompasses all other hair types (face, armpits, etc.).
Process Overview
The laboratory processing of a drug test result primarily involves four steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of integrating a sample into a laboratory’s system. This step involves confirming the sample’s seal and proper shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry that the electronic chain of custody system hasn’t provided.
Screening serves as a preliminary rapid check for the presence of drugs. Although Screening is an economical approach to rule out drug usage for most samples, a positive result necessitates confirmation for court acceptability. Samples that test presumptively positive during Screening require a secondary confirmation.
For samples testing presumptively positive during Screening, additional hair is extracted from the original specimen for the Extraction phase. Here, drugs are isolated from hair at much lower concentrations compared to other methodologies (e.g., urine or oral fluids), making hair drug screening among the most challenging methodologies.
Any positive screening result is validated via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples are cleansed as necessary. The complete laboratory process, from Accessioning to Confirmation, is thoroughly assessed following both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standard accreditation.

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.
