In Leopolis, Wisconsin, Accredited Drug Testing offers comprehensive hair follicle analysis. Whether it's for drugs or alcohol, our testing centers nationwide, including all major cities, provide specialized hair testing solutions. Typically, hair from the crown, requiring 1.5 to 2 inches, or body hair when necessary is used. Results can focus on drugs, alcohol/ETG, or be tailor-made to your needs.
The hair follicle test has become a preferred method in recent times. Employers, legal entities, and substance abuse experts increasingly favor it over urine tests. Organizations with strict no-drug policies or persons on probation find it invaluable. The standout advantage of hair testing is its extended detection timeline, which can go back up to 90 days. It offers an observed collection, making tampering nearly impossible. Yet, for drug use detection within the past 5 days, urine tests remain unmatched.

Hair testing has emerged as an effective means for identifying drug and alcohol consumption. Hair retains a long-term record of alcohol and drug usage by capturing biomarkers within the strands' fibers as they grow. When collected close to the scalp, hair can reveal alcohol and drug use for up to roughly three months. Collection is straightforward, tampering is challenging, and shipping is convenient.
A 1.5-inch section comprising roughly 200 hair strands (comparable to a #2 pencil width) nearest the scalp provides 100mg, the optimal sample for initial analysis and validation. For EtG, optional tests, and/or those exceeding 10 panels, a 150mg sample is advised. We suggest measuring the sample using a jeweler’s scale. Should scalp hair be unavailable, an equivalent body hair sample may be utilized. References to head hair specifically mean scalp hair. Body hair denotes all other forms (facial, axillary, etc.).
Process Overview
The key steps in processing a drug test in a lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the first step of integrating a sample into a lab’s system. This phase ensures the sample is sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any missing data not covered by an electronic custody chain.
Screening provides an initial rapid verification for drug abuse. While cost-effective for eliminating drug use in most samples, a confirmed positive screen is necessitated for legal admissibility. Samples presumptively positive in Screening need further confirmation.
If a sample registers presumptively positive during Screening, additional hair is extracted from the initial sample and readied for Extraction. During Extraction, drugs are isolated from hair at lower concentrations compared to other methods (i.e., urine or oral fluid), making hair drug testing challenging to execute.
Confirmation of any positive screen is achieved via GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo washing as necessary before confirmation. The total lab process from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although commonly known as "hair follicle tests", these tests analyze the hair shaft, not the scalp's follicle.

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.
