In Challenge, California, Accredited Drug Testing provides comprehensive hair follicle drug tests. If you're in need of a hair or alcohol test, our expertise in hair testing is unmatched and we feature facilities across all major cities Nationwide for your convenience. Typically, 1.5 to 2 inches of crown or body hair is necessary. Tests can detect drugs, alcohol/ETG, or include custom options.
Hair follicle drug testing has increasingly become prevalent in recent years. Employers, legal courts, and Substance Abuse experts often prefer hair tests over standard urine tests. This method is favored by zero-tolerance policy employers, courts, and for those on probation due to its extended detection window, up to 90 days, collected under supervision. Despite this, for recent drug use detection, urine tests still prove highly effective within a 5-day frame.

Hair testing is widely recognized as a significant method for identifying substance and alcohol usage. The hair captures long-term evidence of alcohol and drugs by embedding biomarkers within the fiber of the growing hair. If obtained near the scalp, hair offers around a 3-month detection timeframe for substances and alcohol. It's straightforward to gather, challenging to tamper with, and convenient to send.
A segment of 1.5 inches consisting of roughly 200 hair strands (equivalent to a #2 pencil’s width) near the scalp provides 100mg of hair, optimal for analysis and verification. For EtG, enhancements, and/or tests exceeding 10 panels, a 150mg sample is advised. The specimen should be weighed on a jeweler’s scale. If head hair isn't available, a similar amount of body hair can be used. When discussing head hair, we mean scalp hair specifically. Body hair pertains to all other types (facial, axillary, etc.).
Process Overview
The principal phases within the lab processing for a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the preliminary handling of a specimen within a lab’s framework. This covers confirming the sample was appropriately sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and finishing any further data documentation not given by an electronic chain of custody framework.
Screening constitutes an initial rapid assessment for drug misuse. While Screening offers a cost-efficient method to rule out drug consumption for most specimens, a favorable screen must be validated to be permissible in legal settings. Any samples that are tentatively positive during Screening need subsequent confirmation.
In case a sample is tentatively positive during the Screening process, additional hair is extracted from the original sample and arranged for Extraction. Here, substances are retrieved from hair at a much reduced concentration compared to other methods (e.g., urine or oral fluid), explaining why hair drug screening is particularly difficult to execute.
Verification of any favorable screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Every tentatively positive sample undergoes a washing procedure prior to verification as essential. The entire lab process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair label and the recognition of ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Though often called "hair follicle tests", the assessment examines the hair strands themselves, not the follicles located under 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.
