In Grant Park, Illinois, Accredited Drug Testing offers comprehensive hair follicle drug testing services. With a need for hair drug or alcohol screening, our speciality lies in hair assessments, available at our centers across all cities Nationwide.

Hair follicle drug tests have become a go-to method in recent years for screening. Many employers, legal systems, and substance misuse experts prefer hair drug testing over urine tests. These tests prove invaluable for employers enforcing a no-drug policy, judicial purposes, and probation oversight. Their notable advantage is the ability to detect drug use over a prolonged timeframe of up to 90 days, being collected under supervision and challenging to manipulate. However, for detecting substances used in the last 5 days, urine tests remain the gold standard.

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 recognized as an effective method for identifying drug and alcohol consumption. Hair captures a long history of alcohol and drugs by encapsulating markers within the strands as they grow. When clipped near the scalp, hair can provide up to a 3-month timeframe for identifying drugs and alcohol. Gathering hair samples is straightforward, challenging to tamper with, and simple to transport.
A hair sample measuring 1.5 inches with roughly 200 strands (comparable to the width of a #2 pencil) nearest to the roots will yield 100mg of hair, which is the perfect size for both screening and confirmation tests. For EtG, additional tests, or any test exceeding 10 panels, a sample size of 150mg is advised. It's beneficial to use a jeweler’s scale for weighing the sample. If scalp hair isn’t available, an equivalent mass of body hair can be utilized. When we mention head hair, it solely refers to scalp hair. Body hair encompasses all other hair types (such as facial or axillary).
Process Overview
The laboratory process for determining drug test outcomes encompasses four main phases: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes preliminary processing into the lab's system. This step entails checking that the sample was sealed and dispatched correctly, attributing a random LAN (Laboratory Accessioning Number), and performing any supplementary data entry not included via an electronic custody system.
Screening serves as an initial, swift evaluation for substance abuse. While it offers a cost-efficient means to eliminate the possibility of drug use in most samples, a positive result on this initial screen must be verified for it to hold up in legal proceedings. Any samples flagged with presumptive positives during Screening necessitate a subsequent confirmation step.
When a sample tests presumptively positive at the Screening phase, an additional hair portion is extracted from the original sample and is readied for Extraction. In this phase, drugs are withdrawn from the hair at markedly lower concentrations than in other methods (e.g., urine or oral fluid), which is the reason hair drug testing is particularly challenging.
Confirmation of any positive screen outcome occurs through methods such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed pre-confirmation as required. The full lab procedure—from Accessioning to Confirmation—is examined under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Despite often being named "hair follicle tests", the examination targets the hair shaft rather than the follicle beneath the skin.

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.
