Accredited Drug Testing offers extensive hair follicle drug testing services in Keeneyville, Illinois. Whether you're in need of a hair drug or alcohol screening, our expertise lies in hair testing, and we operate testing facilities in every city across the nation capable of conducting these tests. In most instances, at least 1.5 to 2 inches of hair from the crown of the head or body is required. Hair tests are suitable for detecting drugs, alcohol/ETG, and can be customized for other specific hair test options.
Recently, the approach to drug testing has increasingly involved hair follicle testing. This method is increasingly demanded by employers, judicial systems, and Substance Abuse professionals, preferring it over the standard urine test. Zero-tolerance employers, courts, and probationers opt for hair drug testing due to its extended detection period, typically covering up to 90 days. Also, the observed sample collection makes it almost impossible to tamper with. However, for testing recent drug use within the past 5 days, the urine test remains the most reliable.

Hair testing is increasingly recognized as a robust method for identifying drug and alcohol consumption. Hair serves as a long-term record of substance use by preserving biomarkers within the fibers of the growing hair strand. When hair is collected near the scalp, it offers roughly a 3-month detection period for both alcohol and other drugs. It is easy to collect, hard to adulterate, and straightforward to transport.
A 1.5-inch hair sample containing approximately 200 strands, comparable to the thickness of a #2 pencil, provides 100mg of hair, which is the perfect quantity for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale for weighing. If scalp hair is not available, an equivalent amount of body hair may be used. When discussing head hair, we specifically mean scalp hair. Body hair includes all other hair types like facial and axillary.
Process Overview
The main four steps in the laboratory processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial processing of a sample into a laboratory's system, involving verification that the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and any additional data entry that might not be included in an electronic chain of custody system.
Screening is a preliminary assessment for substances of abuse. Although Screening is economically efficient for ruling out drug use in many samples, any positive screen needs verification to be suitable for court purposes. Samples that are presumptively positive in Screenings require further confirmation.
If a sample tests presumptively positive during the Screening phase, additional hair is pulled from the initial sample and prepared for Extraction. During this phase, drugs are extracted from hair at far lower concentrations than through other methods (e.g., urine or oral fluid), which makes hair drug screening one of the hardest methodologies to execute.
Confirmation of any positive screening result is carried out using GC/MS, GC/MS/MS or LC/MS/MS. Prior to confirmation, all presumptive positive samples undergo washing as necessary. The comprehensive laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and in accordance with ISO / IEC 17025 accreditation.

Limitations:
Note: Though commonly called "hair follicle tests", the actual test evaluates the hair strand and 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.
