Accredited Drug Testing provides comprehensive hair follicle drug assessments in Greenbrae, California. If you're in need of a hair drug or alcohol evaluation, our expertise lies in hair analysis, and we boast testing facilities across all cities nationwide capable of conducting hair tests. Typically, 1.5 to 2 inches of hair from the scalp or body are needed. These tests can scrutinize for drugs, alcohol/ETG, or other tailored hair analysis options.
In recent times, the approach to drug screening has increasingly involved hair follicle drug evaluations. Numerous employers, judicial systems, and substance abuse experts now opt for hair tests over traditional urine tests. Hair follicle analyses are chosen by employers with strict zero-tolerance policies for drug use, court systems, and those on probation. A key advantage of hair follicle tests is their extended detection window, often reaching up to 90 days, conducted under observation, and almost impossible to manipulate. Nonetheless, for drug use within the last 5 days, urine tests remain the most accurate.

Recognized as a compelling method, hair testing has become integral in identifying drug and alcohol consumption. By capturing biomarkers within the hair strand's fibrous growth, hair provides an extensive timeline of alcohol and other drugs. When taken near the scalp, hair offers a detection scope of nearly three months for alcohol and drugs. It is straightforward to gather, notably challenging to tamper with, and simple to transport.
A hair sample of 1.5 inches, approximately 200 strands (roughly matching a #2 pencil in size), adjacent to the scalp yields 100mg, which is the optimal amount for evaluation and confirmation. For EtG, additional requests, or panels exceeding 10, a specimen of 150mg is suggested. Utilizing a jeweler’s scale for weighing the sample is advised. Should scalp hair be unavailable, an equivalent amount of body hair can be used. References to head hair are exclusively about scalp hair, while body hair includes all other types such as facial or axillary hair.
Process Overview
The procedure of processing a drug test result in a laboratory comprises four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the introductory process of integrating the sample within a laboratory’s framework. This phase involves ensuring the sample is properly sealed and sent, assigning a LAN (Laboratory Accessioning Number) randomly, and fulfilling any extra data entry absent from an electronic chain of custody system.
Screening is a preliminary, swift examination for substances of abuse. While it serves as a cost-efficient method to eliminate drug use in most cases, any positive outcome requires confirmation to be legitimate for legal proceedings. Presumptive positive samples in Screening necessitate secondary affirmation.
For presumptively positive samples in Screening, extra hair is extracted from the original specimen for the Extraction stage. Here, drug removal from hair is undertaken at a much reduced concentration compared to other techniques (such as urine or oral fluid), underscoring the complexity of performing hair drug screening.
Positive screening outcomes undergo confirmation using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples are cleansed pre-confirmation as necessary. The entire lab process from Accessioning to Confirmation is inspected under both the CAP (College of American Pathologists) Hair designation 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.
