Accredited Drug Testing offers comprehensive hair follicle drug screenings in Avalon, Wisconsin. For those requiring a hair drug or alcohol test, our expertise is in hair testing, with facilities across all U.S. cities ready to conduct such assessments. Typically, having 1.5 to 2 inches of hair from the head or body allows for testing. Our analyses can cover drugs, alcohol/ETG, and other tailored hair test options.
Hair follicle testing has become an increasingly popular method for drug detection in recent years. Many employers, judicial bodies, and substance abuse professionals favor hair tests over traditional urine tests. Employers with strict anti-drug-use policies, courts, and probation officers frequently use hair tests. A major advantage is the extended detection window, often reaching 90 days. This process is nearly foolproof and involves an observed collection. Nonetheless, for drug use within the past 5 days, urine tests remain the most precise.

Hair analysis is now recognized as an effective instrument for identifying drug and alcohol intake. Hair maintains a long-term record of alcohol and drug consumption by embedding biomarkers within the growing hair strand fibers. When cut near the scalp, hair can indicate alcohol and drug use up to roughly a 3-month span. Hair collection is straightforward, challenging to tamper with, and convenient to send.
A 1.5-inch portion of approximately 200 hair strands (comparable to the width of a #2 pencil) nearest the scalp will yield 100mg of hair, which is the optimal quantity for both screening and verification. For EtG, additional analyses, and/or tests exceeding 10 panels, 150mg of the hair sample is suggested. We advocate measuring the sample using a jeweler’s balance. If scalp hair is not present, a comparable quantity of body hair might be gathered. By head hair, we mean only scalp hair, whereas body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
The laboratory process for a drug test encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial introduction of a sample into a lab's system. It involves confirming correct sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not covered by an electronic chain of custody protocol.
Screening involves a preliminary check for drugs of abuse. Though Screening is a cost-efficient method to reject drug use for most samples, a positive result needs confirmation for legal admissibility. Samples that are tentatively positive in Screening must undergo secondary verification.
Should a sample show presumptive positivity in the Screening phase, additional hair from the initial sample is prepared for Extraction. Here, drugs are drawn from hair at significantly lower concentrations than in other methods (like urine or oral fluid), which accounts for the complexity of hair drug screening.
Confirmation of any positive Screening outcome employs GC/MS, GC/MS/MS, or LC/MS/MS. All tentatively positive samples undergo washing before confirmation if needed. The entire lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair recognition and ISO / IEC 17025 certification standards.
Advantages of hair drug testing:
Limitations:
Note: Although frequently called "hair follicle tests", the procedure actually examines the hair strand instead of 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. 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.
