In Cologne, Minnesota, Accredited Drug Testing excels at providing comprehensive hair follicle drug assessments. Whether it's for drugs or alcohol, our specialty lies in hair examinations, supported by numerous testing facilities across the country. A minimum of 1.5 to 2 inches of hair from your head or body is generally required. Tests are capable of detecting drugs, alcohol/ETG, or can be tailored for other specific analyses.
Hair follicle drug tests have become increasingly popular in recent years for drug screening. Organizations, judicial systems, and substance abuse experts now often prefer this method over traditional urine tests. Employers with a zero-tolerance policy, courts, and individuals on probation leverage the extended detection window, around 90 days, that hair testing provides. While nearly tamper-proof, urine tests still hold precedence for recent usage detection within a 5-day timeframe.

Recognized for its efficacy, hair testing stands as a potent mechanism for uncovering drug and alcohol consumption. Hair fibers ensnare biomarkers from drugs and alcohol, preserving a lasting record within the growing strand. Collecting hair near the scalp offers a detection span of up to 90 days for alcohol and drug presence. Hair collection is straightforward, challenging to tamper with, and convenient for transport.
A 1.5-inch strand sample, roughly equivalent to 200 hairs or a #2 pencil's girth, near the scalp grants 100mg of hair, suited for screening and verification. For EtG, additional components, and tests exceeding 10 panels, a 150mg specimen is suggested. It's best to verify specimen weight with a jeweler's scale. In the absence of scalp hair, an equivalent quantity of body hair can be gathered. The term head hair specifically denotes scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
Four principal stages define the lab process for drug test results: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the primary phase of integrating a sample into a lab’s framework. This step involves confirming the sample’s proper sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and completing extra data entry omitted by an electronic chain of custody.
Screening performs an initial, efficient check for substance abuse. While Screening is cost-efficient for eliminating drug use in most cases, a positive result mandates confirmation to be court-admissible. Any initially positive samples necessitate subsequent confirmation.
A positive indication in the Screening stage leads to more hair being extracted from the initial specimen for Analysis. Here, drugs are extracted at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug testing.
Confirmation of positive Screening findings is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed prior to necessary confirmations. The entire lab procedure, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair criteria and the ISO/IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly known as "hair follicle tests", these tests scrutinize the hair strand itself, 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.
