In Marion, Illinois, Accredited Drug Testing offers comprehensive hair follicle drug tests. Specializing in hair and alcohol testing, our centers throughout the nation can conduct these tests. Usually, 1.5 to 2 inches of head or body hair is needed. Hair tests assess for drugs, alcohol/ETG, or other specific test options.
Recently, hair follicle drug tests have become more common in drug testing practices. Employers, judicial systems, and substance abuse professionals opt for hair tests over urine tests. A key advantage is their extended detection span—up to 90 days—making them tough to trick. That said, urine tests remain most precise for recent drug use within 5 days.

When you're searching for hair drug testing near me or hair drug testing locations, we provide a simple and convenient process to find a drug and alcohol testing location near you that is certified to provide all of your drug and alcohol testing needs.
Hair testing is now recognized as an effective method for identifying drug and alcohol intake. Hair retains a comprehensive history of alcohol and drug consumption by capturing biomarkers within the strands as they grow. When collected near the scalp, hair offers approximately a 3-month detection window for alcohol and drugs. It is easy to collect hair, somewhat resistant to tampering, and convenient to ship.
A 1.5-inch sample containing roughly 200 strands of hair (the size of a #2 pencil) closest to the scalp provides 100mg of hair, which is the optimum sample for screening and confirmation. For EtG, add-ons, and tests exceeding 10 panels, 150mg of the specimen is advised. We suggest using a jeweler’s scale to weigh the specimen. If scalp hair is not available, an equivalent amount of body hair can be gathered. When mentioning head hair, it specifically refers to scalp hair. Body hair pertains to all other types (facial, axillary, etc.).
Process Overview
The process for laboratory handling of a drug test outcome involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the first step of processing a sample within a lab's system. This step includes confirming that the sample is properly sealed and shipped, assigning it a random LAN (Laboratory Accessioning Number), and completing any missing data entry not covered by an electronic chain of custody system.
Screening is a quick initial test for drug abuse detection. Although Screening is an economical way to rule out drug use for most samples, a positive screen must be followed by a confirmation for legal admissibility. Any samples that are presumptively positive in Screening need a secondary confirmation.
If a sample tests presumptively positive during Screening, additional hair is taken from the original specimen for Extraction. Drugs are extracted from the hair at lower concentrations than other methods (such as urine or oral fluid), making hair drug screening challenging to perform.
The confirmation of a positive screening result is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo a necessary pre-confirmation wash. The complete lab process, from Accessioning to Confirmation, is evaluated under CAP (College of American Pathologists) Hair designation and accreditation to 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.
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.
