Accredited Drug Testing offers thorough hair follicle drug tests in Poynette, Wisconsin. When you require testing for drugs or alcohol via hair samples, we specialize in these analyses and operate centers across the nation, including a hair testing facility in each city. Typically, hair at the crown must be 1.5 to 2 inches for testing, though body hair can suffice. Our tests detect drugs, ETG/alcohol, or can be customized to suit your testing needs.
In recent times, hair follicle drug tests have become more favored in drug testing procedures. Employers, judicial systems, and substance abuse counselors often mandate a hair test over a urine test. Organizations with zero-tolerance policies use hair tests, as do court systems and probationary supervisors. The biggest advantage of hair tests is their ability to show drug use over an extended period, up to 90 days, as they are closely monitored and hard to alter. However, for detecting recent drug use within five days, urine tests remain more precise.

Hair testing is increasingly recognized as a powerful means for identifying drug and alcohol consumption. Hair offers a lengthy historical record of substance intake by retaining biomarkers within its fibers. When taken close to the scalp, hair can offer a detection window of up to about 3 months for alcohol and other substances. Hair collection is straightforward, somewhat challenging to tamper with, and simple to transport.
A 1.5-inch sample comprised of roughly 200 hair strands (similar in size to a #2 pencil) near the scalp yields 100mg of hair, making it the preferred sample size for screening and confirmation. For EtG, additional testing, and/or analyses exceeding 10 panels, 150mg of hair is advised. We suggest using a jeweler’s scale to measure the sample weight. If scalp hair is not accessible, an equivalent quantity of body hair may be obtained. When mentioning head hair, we exclusively mean scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial handling of a sample within a laboratory’s system. This step includes ensuring the sample was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data input not available through an electronic chain of custody mechanism.
Screening entails an initial rapid assessment for drug abuse. While Screening is an economical method to exclude drug use in most samples, a positive result requires confirmation to be legally valid. Any samples with a presumptive positive in Screening require a follow-up confirmation.
If the Screening stage reveals a presumptive positive, additional hair is extracted from the original sample for the Extraction process. During this process, drugs are extracted from hair at a lower concentration compared to other methods (e.g., urine or oral fluid), contributing to the challenges of hair drug screening.
Confirmation of any positive screening outcomes is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with a presumptive positive are cleansed prior to confirmation if required. The entire processing chain from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Limitations:
Note: Although sometimes termed "hair follicle tests", the analysis is conducted on the hair strand and not the hair follicle beneath the scalp.

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.
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.
