In Jamestown, California, Accredited Drug Testing provides holistic solutions for hair follicle drug assessments. Our expertise in hair screening covers both drug and alcohol analysis, and our centers are available nationwide for convenience. Typically, hair lengths between 1.5 to 2 inches are required, either from the scalp or body, for conducting drug or customized hair analysis.
The preference for hair follicle drug tests has grown, often replacing the traditional urine test among employers, judicial bodies, and Substance Abuse experts. Companies with strict no-drug policies favor hair tests for their extended detection window, covering up to 90 days, and ensuring a tamper-proof procedure. Nonetheless, urine tests remain superior for identifying very recent drug use, typically within the last five days.

Hair screening has emerged as a significant method for identifying usage of drugs and alcohol. Through embedding biomarkers in the fibers of a hair strand as it grows, hair offers a prolonged history of alcohol and drugs. If gathered near the scalp, hair provides an approximate 3-month detection timeframe for drugs and alcohol. It is easy to gather, relatively challenging to tamper with, and straightforward to transport.
A 1.5-inch portion consisting of roughly 200 hair strands (comparable to a #2 pencil's width) nearest to the scalp yields 100mg of hair, the ideal for testing and confirmation. For EtG, add-ons, or when testing beyond 10 panels, a 150mg specimen is suggested. We advise measuring the specimen using a jeweler’s scale. In the absence of scalp hair, a similar amount of body hair is suitable. Reference to head hair pertains solely to scalp hair. Body hair refers to all hair types elsewhere (facial, axillary, etc.).
Process Overview
The primary stages in the laboratory handling of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails initially processing a sample into a laboratory system. This involves checking the proper sealing and shipment of the sample, assigning it a random LAN (Laboratory Accessioning Number), and fulfilling any extra data entry absent from an electronic chain of custody protocol.
Screening constitutes a preliminary rapid check for drugs of abuse. Although Screening is cost-efficient for ruling out drug usage in most samples, a positive screen necessitates confirmation to be court-admissible. Any samples flagged as presumptively positive during Screening will need further confirmation.
If a sample is considered presumptively positive in Screening, additional hair is extracted from the original sample and readied for Extraction. At this stage, drugs are obtained from hair in notably lower concentrations than other methods (like urine or oral fluid), presenting a challenge in hair drug screening execution.
Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to confirmation when needed. The entire lab operation from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair label and the ISO / IEC 17025 accreditation.

Note: Despite being commonly termed "hair follicle tests," the analysis targets the hair strand, not the follicle beneath 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.
