Accredited Drug Testing provides comprehensive hair follicle drug tests in Big Oak Flat, California. For those requiring hair drug or alcohol assessments, we're experts in hair testing, with facilities across all cities nationwide to conduct the test. Generally, 1.5 to 2 inches of hair from the crown or body is necessary. Hair tests evaluate drugs, alcohol/ETG, or offer tailored hair testing solutions.
Lately, drug testing methods have increasingly integrated hair follicle testing. Many employers, judicial systems, and Substance Abuse authorities now prefer hair tests over conventional urine tests. Organizations with stringent anti-drug policies, courts, and probation subjects often use hair tests. These tests' advantage lies in a longer drug detection window, typically up to 90 days, with observed collection making them hard to fake. Yet for recent drug use (within 5 days), urine tests remain more precise.

Hair analysis has gained acceptance as an effective method for detecting alcohol and drug consumption. Hair strands offer a comprehensive history of substance usage by embedding biomarkers within the fibers of the hair as it grows. When obtained close to the scalp, hair can offer a detection period of up to about three months for both alcohol and drugs. It's easy to collect, hard to tamper with, and straightforward to transport.
A 1.5-inch section of approximately 200 hair strands (roughly the circumference of a #2 pencil) nearest to the scalp yields 100mg, which is an optimal sample size for both screening and confirmation. For EtG, additional tests, or tests exceeding 10 panels, a 150mg sample is advisable. Utilizing a jeweler’s scale for weighing the sample is suggested. If scalp hair isn't available, an equivalent amount of body hair can be used. References to head hair specifically mean scalp hair. Body hair encompasses all other hair types (like facial or axillary hair).
Process Overview
The key stages in laboratory processing of drug tests include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary incorporation of the sample into the lab system. This step ensures the sample was properly sealed and sent, allocates a LAN (Laboratory Accessioning Number), and finalizes any supplementary data entry not available through an electronic custody chain system.
Screening acts as a preliminary check for substance abuse. While it’s an economically feasible method to dismiss most drug usages, a positive result requires confirmation for legal validation. Any sample with a presumptive positive in Screening necessitates further confirmation.
In cases where a sample shows a presumptive positive in Screening, more hair is retrieved from the initial sample and prepped for Extraction. Here, drugs are isolated from the hair at much lower concentrations than other methods (e.g., urine or oral fluids), making hair drug testing the most intricate method to conduct.
To confirm any positive screenings, GC/MS, GC/MS/MS, or LC/MS/MS methods are employed. Samples with presumptive positives undergo washing as needed before confirmation. The complete lab process, from Accessioning to Confirmation, adheres to the CAP (College of American Pathologists) Hair criteria and the 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.
