Accredited Drug Testing offers thorough hair follicle drug assessments in Colby, Wisconsin. For those requiring a hair drug or alcohol screening, we specialize in such tests and maintain facilities nationwide to accommodate these needs. Typically, 1.5 to 2 inches of hair is necessary from the crown or body. These tests can determine drug, alcohol/ETG presence or be tailored for specific needs.
Hair follicle drug testing has become a preferred method for screening substance use. Many employers, legal systems, and substance abuse experts are opting for it over urine tests. Employers enforcing zero-tolerance policies, judicial bodies, and probationary individuals choose this method primarily due to its extended detection window of up to 90 days, reliability, and resistance to manipulation. For identifying drug use within the past 5 days, urine tests remain the most precise.

Recognized as an effective method for identifying substance use, hair testing provides an extended timeline for detecting alcohol and drug presence by capturing indicators within the strands. When sourced near the scalp, hair offers a detection range of up to 3 months for such substances. Collecting hair is straightforward, challenging to tamper with, and convenient for transport.
A sample of 1.5 inches consisting of roughly 200 hair strands (comparable to the girth of a #2 pencil) from the scalp yields 100mg, which is optimal for both screening and verification. For tests like EtG, add-ons, or those exceeding 10 panels, 150mg of the sample is advised. It is suggested to measure this on a jeweler’s scale. In the absence of scalp hair, collecting a similar quantity from body hair is an option. When discussing head hair, we focus solely on scalp hair. Body hair encompasses all other types (e.g., facial, axillary).
Process Overview
The key phases in lab processing of drug test results include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is concerned with the preliminary assimilation of a sample into the lab's system. This step involves confirming the sample’s seal and shipment accuracy, assigning it a random LAN (Laboratory Accessioning Number), and completing any data entry that was not supplied by an electronic chain of custody system.
Screening is a preliminary drug abuse assessment. Although cost-effective in excluding drug use for most samples, a positive screen necessitates confirmation for legal proceedings. Any samples that show potential positivity in Screening require additional confirmation.
Should a sample exhibit potential positivity during Screening, further hair is extracted from the original sample for the Extraction phase. Here, drugs are extracted from the hair at significantly lower concentrations relative to other methods (e.g., urine or oral fluid), contributing to the complexity of hair drug screening.
Confirmation of any positive findings from Screening is performed through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All potentially positive samples undergo necessary washing before confirmation. The entire lab procedure from Accessioning through Confirmation undergoes scrutiny under both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditations.

Drawbacks:
Note: The tests often called "hair follicle tests" actually evaluate the hair strand, not 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.
