Accredited Drug Testing offers comprehensive hair follicle drug testing services in Lyndon Station, Wisconsin. If you require a hair drug or alcohol test, Accredited Drug Testing is your go-to specialized in hair testing. We have testing locations across all cities nationwide prepared to conduct a hair test. Generally, you need to have 1.5 to 2 inches of hair from your head's crown or body. Hair tests are capable of analyzing drugs, alcohol/ETG, or other tailor-made hair testing options.
In recent times, drug testing procedures have increasingly incorporated hair follicle drug tests. Many employers, courts, and professionals working with substance abuse now prefer a hair drug test over the conventional urine test. Hair follicle drug tests are favored by employers with zero-tolerance policies, legal institutions, and probationary individuals. The main advantage of a hair follicle drug test is it allows for a prolonged detection period, potentially up to 90 days. The collection process is observable and virtually impossible to tamper with. However, a urine test remains the most accurate for drug use detected within the past 5 days.

Hair testing has emerged as an effective mechanism for identifying drug and alcohol consumption. Hair captures a prolonged timeline of substance use by encasing biomarkers within the strands of growing hair. When collected near the scalp, a hair sample can offer up to an approximate 3-month period for detecting various substances such as alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and easy to transport.
A 1.5-inch portion of around 200 hair strands (akin to the thickness of a #2 pencil) from near the scalp yields 100mg of hair, ideal for both screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a 150mg sample is advisable. We suggest measuring the sample with a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair can be collected. "Head hair" pertains exclusively to scalp hair, while "body hair" encompasses all other types (such as facial and axillary).
Process Overview
The laboratory processing of drug test results follows four fundamental steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the initial phase of integrating a specimen within a laboratory’s framework. This process entails confirming the proper sealing and shipping of the sample, assigning it a LAN (Laboratory Accessioning Number) randomly, and completing any supplementary data entry not accommodated by an electronic chain of custody system.
Screening serves as a preliminary, rapid evaluation for drug abuse signs. While it is a cost-efficient method to exclude drug use among most samples, a court-admissible positive screen mandates confirmation. Samples presumptively positive during Screening necessitate a follow-up confirmation.
In cases of presumptive positives during Screening, additional hair is extracted from the initial specimen for the Extraction phase. This phase involves extracting drugs from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), hence hair drug screening is notably demanding.
To verify any positive screening outcome, techniques like GC/MS, GC/MS/MS, or LC/MS/MS are employed during Confirmation. Prior to Confirmation, presumptive positive samples undergo cleansing as applicable. The entire process from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and holds accreditation to ISO / IEC 17025 standards.

Limitations:
Note: Despite being labeled as "hair follicle tests", the analysis targets the hair strand rather than 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.
