Accredited Drug Testing offers comprehensive hair follicle drug evaluations in La Farge, Wisconsin. For those in need of hair drug or alcohol tests, we are experts in this type of testing. Our nationwide centers, found in every city, are equipped for these tests. Most cases require at least 1.5 to 2 inches of hair from the crown or body for analysis. Hair tests can detect drugs, alcohol/ETG, or can be tailored for specific testing needs.
In recent trends, drug testing often includes hair follicle examinations. Employers, judicial systems, and substance abuse experts now favor hair testing over standard urine testing. These tests are ideal for workplaces with stringent drug policies, legal authorities, and probationers. The notable advantage of hair follicle testing is its extended detection window up to 90 days, with a closely monitored sample collection process that minimizes cheating. For detecting recent drug use, within the past 5 days, urine tests still hold the highest accuracy.

Hair testing is now recognized as an effective means for identifying drug and alcohol consumption. Hair captures a prolonged history of substances by embedding biomarkers within the fibers of the hair as it grows. When obtained near the scalp, hair can reveal a detection period of up to three months for alcohol and drugs. Collecting hair is straightforward, challenging to alter, and facilitates easy transportation.
A sample size of 1.5 inches, consisting of roughly 200 hair strands (comparable to a #2 pencil diameter) nearest to the scalp, yields 100mg of hair, which is ideal for both screening and confirmation. For tests involving EtG, add-ons, or those exceeding 10 panels, a specimen weight of 150mg is suggested. It's advisable to weigh the sample using a jeweler's scale. If scalp hair isn't accessible, a corresponding quantity of body hair may be obtained. When mentioning head hair, it specifically refers to scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).
Process Overview
The primary stages in the laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a sample into a laboratory's system. This process verifies proper sealing and shipping of the sample, assigns a unique LAN (Laboratory Accessioning Number), and completes any necessary data entry that's not captured by an electronic chain of custody system.
Screening performs an initial rapid evaluation for drug substances. While Screening is an economical method to exclude drug usage in most samples, a positive screen must be confirmed for court admissibility. Samples that are preliminarily positive in Screening need secondary confirmation.
Should a sample test positive preliminarily in the Screening phase, additional hair is taken from the original sample and readied for Extraction. This phase extracts drugs from hair at significantly lower concentrations than other methods (such as urine or oral fluid), which is why hair drug screening is the most challenging to execute.
Confirmation for any positive screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are washed before confirmation as deemed necessary. The complete laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair accreditation and the ISO / IEC 17025 standards.

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.

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.
