In Angels City, California, Accredited Drug Testing provides comprehensive hair follicle drug testing. For those in need of a drug or alcohol hair test, our expertise lies in hair testing, available at testing centers across the nation. Generally, 1.5 to 2 inches of hair from your head’s crown or body can be used. These tests can detect drugs, alcohol/ETG, or be customized for other requirements.
In recent times, hair follicle drug tests are being increasingly adopted for drug screenings. Employers, legal systems, and substance abuse experts are opting for hair tests over standard urine tests. Employers with zero-tolerance policies, courts, and those on probation often utilize these tests. A key advantage of hair tests is the significantly longer drug detection window, reaching up to 90 days, with a witnessed collection process that’s tough to bypass. Nonetheless, for detecting recent drug use within five days, urine tests remain the most accurate.

Hair analysis is recognized as an effective method for identifying alcohol and drug use. The hair captures biomarkers in the strands as they grow, offering a prolonged record of substance usage. Obtaining samples near the scalp can reveal approximately a three-month insight into alcohol and drug usage. Collection is straightforward, adjusting the sample is challenging, and transportation is convenient.
A sample measuring 1.5 inches with about 200 hairs (similar to the thickness of a #2 pencil) near the scalp yields 100mg, optimal for both screening and confirmation. For EtG, supplementary tests, and tests beyond 10 panels, a 150mg specimen is advisable. It's suggested to use a jeweler’s scale to measure the sample. If scalp hair is unavailable, a matching amount of body hair can be collected. "Head hair" indicates scalp hair only. "Body hair" encompasses all other hair types (e.g., facial, axillary).
Process Overview
The key phases in processing a drug test result in a lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts with integrating a sample into the laboratory's system, ensuring correct sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any missing data entry if not available electronically.
Screening conducts a preliminary check for drug abuse. Although Screening efficiently rules out drug usage for most samples, any positive results require confirmation to be valid in legal settings. Positive samples from Screening need a secondary validation.
Presumptive positives in the Screening lead to more hair samples from the initial collection for Extraction. During Extraction, the drug concentration extracted from hair is much lower than other methods (e.g., urine, oral fluid), emphasizing the complexity of hair drug testing.
Confirmation of positive Screening outcomes uses GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive samples undergo washing as needed before confirmation. The whole lab process from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) Hair designation and 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.
