Accredited Drug Testing provides comprehensive services for hair follicle drug testing in Northwest Marin, California. For those needing a hair drug or alcohol evaluation, our expertise in hair testing is unmatched, with facilities across all cities nationwide ready to conduct these tests. Typically, 1.5 to 2 inches of head or body hair is necessary. This method can detect drugs, alcohol/ETG, or other bespoke hair testing needs.
Recently, hair follicle drug tests have increasingly become a preferred method of drug screening. Many employers, judicial systems, and substance abuse experts now favor these over standard urine analyses. This testing approach is particularly popular with organizations enforcing stringent drug-free mandates, judicial courts, and for those on probation. Its primary advantage is the longer drug detection window, often up to 90 days, facilitated by a monitored collection process, with almost no chance of falsification. However, for identifying drug use within the previous five days, urine tests remain unparalleled in accuracy.

Hair analysis has emerged as an effective means for detecting drug and alcohol consumption. It provides a comprehensive record of alcohol and drug usage by capturing biomarkers within the fibers of the hair as it grows. When hair is collected near the scalp, it can offer about a three-month timeframe for detecting alcohol and other substances. Hair collection is straightforward, not easily tampered with, and convenient to transport.
A 1.5-inch segment containing roughly 200 hairs (approximately the diameter of a #2 pencil) from the scalp yields 100mg of hair, the optimal quantity for preliminary screening and confirmation. For tests like EtG, additional screenings, or panels beyond ten, 150mg of the sample is preferred. It's advisable to measure the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent amount of body hair can be utilized. References to head hair specifically mean scalp hair, whereas body hair encompasses other types (facial, axillary, etc.).
Process Overview
The laboratory evaluation of a drug test involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary stage of entering a sample into the laboratory’s system. This includes verifying proper sealing and shipment of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any missing information not already included electronically.
Screening provides a rapid assessment for drugs of abuse. While it's a cost-effective method for initially ruling out drug use, a positive result from Screening must be confirmed for legal acceptability. Presumptive positives in Screening necessitate further confirmation.
For samples deemed presumptive positives during Screening, additional hair is extracted from the original sample and prepared for Extraction. At this stage, drugs are isolated from hair at much finer concentrations than other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug analysis.
Positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Prior to confirmation, all presumptive positive samples undergo washing as needed. The complete lab process, from Accessioning through Confirmation, is subjected to review under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

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.
