Accredited Drug Testing provides comprehensive hair follicle drug testing services in Little Grass Valley, California. Whether you require a hair drug or alcohol assessment, Accredited Drug Testing excels in this domain and maintains testing facilities across the nation. To conduct a hair test, typically 1.5 to 2 inches of hair is needed from either the head or body. The analysis can target drugs, alcohol/ETG, or be tailored to specific testing needs.
In recent times, the approach to drug testing has increasingly embraced hair follicle analysis. Various employers, judicial systems, and Substance Abuse specialists prefer hair drug tests over traditional urine tests. Employers with strict drug policies, as well as courts and probation officers, favor this method due to its extended detection span of up to 90 days, observed sample collection, and high resistance to tampering. However, for drug use within the last 5 days, urine testing remains the most precise.

Hair examinations have emerged as an efficient means of identifying substance and alcohol consumption. Hair captures a prolonged timeline of alcohol and narcotics by embedding biomarkers within the strands as the hair grows. When samples are taken proximally to the scalp, they can offer an approximate three-month detection span for alcohol and other substances. Hair collection is straightforward, challenging to tamper with, and convenient for shipping.
A 1.5-inch segment comprising roughly 200 hairs (the diameter of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimal amount for both preliminary and confirmatory analysis. For EtG assessments, additional tests, and/or analyses exceeding 10 elements, a 150mg sample is advisable. It is suggested to measure the specimen with a jeweler’s balance. Should scalp hair be inaccessible, an equivalent volume of body hair is suitable for collection. References to head hair are specifically about scalp hair. Body hair denotes all other hair categories (e.g., facial, axillary, etc.).
Process Summary
The primary stages in laboratory processing of a drug analysis are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the preliminary handling of specimens into the laboratory’s framework. This process ensures the sample is properly sealed and dispatched, allocates a unique LAN (Laboratory Accessioning Number), and completes any missing information not captured by an electronic chain of custody system.
Screening entails an initial rapid assessment for controlled substances. Though Screening is an economical method to dismiss most samples' drug use, a positive result necessitates Confirmation to stand in judicial proceedings. Samples presumed positive from Screening mandate secondary Confirmation.
Should a sample show presumptive positivity at Screening, additional hair is extracted from the original sample and readied for Extraction. This stage involves retrieving drugs from the hair at a lower concentration than in alternate methods (e.g., urine or saliva), making hair drug testing the most intricate technique to execute.
Confirmation for all positive screens is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Samples flagged as presumptively positive undergo a wash prior to Confirmation as required. The complete laboratory process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair category and accreditation to ISO / IEC 17025 criteria.

Drawbacks:
Note: Often labeled as "hair follicle tests," this assessment evaluates the strand of hair rather than the beneath-the-scalp 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.
