In Fellows, California, Accredited Drug Testing offers comprehensive hair follicle drug assays. Specializing in hair and alcohol testing, we operate centers nationwide equipped to handle these tests. Typically, 1.5 to 2 inches of hair is required, either from the crown or body. The analysis can screen for drugs, alcohol/ETG, or other tailored options.
Over the years, hair follicle testing has gained traction in drug examinations. It is now favored by employers, judicial systems, and substance abuse experts over urine tests. Those enforcing zero-tolerance policies, courts, or probation officers see its merit. The key advantage is its extensive detection window—up to 90 days—aided by monitored collection, minimizing deception, though urine tests remain best for recent use within five days.

When you're searching for hair drug testing near me or hair drug testing locations, we provide a simple and convenient process to find a drug and alcohol testing location near you that is certified to provide all of your drug and alcohol testing needs.
Hair testing is recognized as a potent method for identifying both alcohol and drug consumption. The strands of hair capture biomarkers throughout their growth, offering an extended timeline of substance use. When obtained near the scalp, hair can indicate drug and alcohol consumption over a span of roughly three months. It is straightforward to collect, resistant to tampering, and simple to transport.
To secure a sample for analysis and verification, a 1.5-inch portion of roughly 200 strands (around #2 pencil thickness) nearest the scalp, equating to 100mg, is optimal. For tests including EtG, add-ons, or exceeding 10 panels, a specimen of 150mg is advised. It is recommended to use a jeweler’s scale to determine the sample's weight. In instances where scalp hair isn't accessible, a comparable quantity of body hair may suffice. The term head hair specifically denotes scalp hair. Body hair encompasses all other hair types (e.g., facial, axillary).
Process Overview
The process for processing a drug test result in a lab includes four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step, involving the integration of a sample into a lab's system. This process verifies the proper sealing and shipment of the sample, assigns it a unique LAN (Laboratory Accessioning Number), and fills in any necessary information not covered by an electronic chain of custody.
Screening offers a preliminary and swift assessment for potential substance abuse. Although cost-effective for ruling out drugs in most samples, a positive screen necessitates confirmation for legal acceptability. Samples deemed presumptively positive in Screening require further confirmation.
Should a sample show presumptive positivity during Screening, additional hair is extracted from the original sample for preparation in Extraction. This step involves deriving drugs from hair at reduced concentrations compared to other methods (e.g., urine, oral fluid), which contributes to the complexity of hair drug screening.
Positive screening results undergo Confirmation through techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Confirmation necessitates cleansing all presumptively positive samples prior. The entire lab procedure, from Accessioning through Confirmation, adheres to both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Limitations:
Note: While commonly called "hair follicle tests," the analysis is actually conducted on the hair strand, not the follicle within the scalp.

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. The research presented in this special issue will undoubtedly shape the future of drug testing and analysis, fostering collaboration and inspiring further innovation in this crucial area of scientific inquiry.
