Accredited Drug Testing provides comprehensive hair follicle drug tests in Finlayson, Minnesota. If you're in need of a hair drug or alcohol test, we specialize in hair analysis, with centers across all cities Nationwide ready to conduct your test. Typically, 1.5 to 2 inches of hair from the head or body are used. Hair tests can assess drugs, alcohol/ETG, or other tailored examinations.
Lately, the hair follicle drug test method has become more common in drug testing practices. Employers, courts, and Substance Abuse professionals are opting for hair tests instead of traditional urine tests. These tests are favored by employers with zero-tolerance policies, the courts, and probation systems for their longer detection period—up to 90 days—acquired through a supervised process, making them difficult to tamper with. However, urine tests remain accurate for detecting very recent drug use, within 5 days.

Hair testing is recognized as a robust method for detecting substance and alcohol use. Hair retains a historical record of alcohol and drugs by capturing biomarkers within the strands' fibers. A sample taken near the scalp can offer a detection period of up to three months for alcohol and various drugs. Hair collection is straightforward, relatively tamper-resistant, and simple to transport.
A sample measuring 1.5 inches from the scalp, containing approximately 200 hairs (around the thickness of a #2 pencil), yields 100mg, an optimal quantity for testing and verification. For EtG, add-ons, or panels exceeding 10, it is advisable to obtain 150mg of the sample. We suggest using a jeweler’s scale for precise measurement. In the absence of scalp hair, an equivalent volume of body hair can be used. When discussing head hair, we mean scalp hair exclusively. Body hair encompasses all other hair categories (facial, axillary, etc.).
Process Overview
The drug test laboratory procedure is comprised of four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial entry of a sample into the lab's system, which entails checking the sample's seal and shipping integrity, assigning a random LAN (Laboratory Accessioning Number), and completing data entry not covered by an electronic chain of custody.
Screening is a preliminary assessment for substance abuse. While cost-effective for excluding drug use in most cases, any positive screening must be corroborated for legal acceptability. Presumptive positive samples from Screening necessitate further verification.
If a sample tests presumptively positive during Screening, more hair is extracted from the initial sample for the Extraction stage. Here, drugs are extracted from hair at lower concentrations compared to other methods (such as urine or oral fluid), explaining why hair drug screening is a complex methodology.
GC/MS, GC/MS/MS or LC/MS/MS techniques are employed to confirm any positive screening results. Presumptive positive samples undergo washing before confirmation as needed. Every stage from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although often termed "hair follicle tests", the analysis pertains to the hair strand, not the 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.
