Accredited Drug Testing offers full hair follicle drug testing in Red River, Wisconsin. If a hair or alcohol test is needed, our centers nationwide, including Red River, are equipped to conduct them. Typically, 1.5 to 2 inches of hair from the head or body is required. Our hair tests can detect drugs, alcohol/ETG, and offer personalized testing options.
The trend toward hair follicle drug tests has increased over the years. Employers, courts, and substance abuse experts often favor these tests over urine tests. They suit zero-tolerance policies held by employers and aid court and probation requirements. Their advantage lies in the longer detection window for substances, usually up to 90 days, and tests are nearly impossible to tamper with. For recent drug use (within 5 days), urine tests remain the gold standard.

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. It captures a prolonged history of substances by embedding biomarkers within the fibers of the hair as it grows. When hair is sampled close to the scalp, it offers a detection period of up to roughly three months for alcohol and other substances. The collection process is straightforward, with hair being relatively tamper-resistant and easy to transport.
Collecting a 1.5-inch segment of approximately 200 hair strands (equivalent in size to a #2 pencil) near the scalp provides about 100mg, an optimal quantity for both initial screening and verification. For tests involving EtG, additional panels, or tests surpassing 10 panels, a 150mg sample is suggested. We advise using a jeweler’s scale to weigh the sample precisely. In the absence of scalp hair, an equivalent volume of body hair may be gathered. When discussing head hair, it specifically refers to scalp hair, while body hair encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The primary stages in analyzing a drug test result at the laboratory include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary handling of a sample entering the lab’s system. This process verifies proper sealing and shipping of the sample, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data entries not captured by an electronic chain of custody system.
Screening includes an initial rapid assessment for abused substances. Although Screening is a cost-efficient method to rule out drug use in most samples, a positive screen must be confirmed for legal validity. Any sample flagged as presumptive positive during Screening mandates further confirmation.
When a sample is flagged as presumptively positive during Screening, additional hair from the original sample is utilized for Extraction. Here, drugs are isolated from the hair at significantly lower concentrations compared to other methods (such as urine or oral fluid). This makes hair drug screening one of the most complex methodologies to execute.
The Confirmation of any positive result from Screening is carried out using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples marked as presumptive positive are cleaned before Confirmation as required. The entirety of the lab procedure, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 standards accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although often labeled as "hair follicle tests," the examination focuses on the hair strand rather than 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.
