Accredited Drug Testing offers comprehensive hair follicle drug testing services in Harvey, Illinois. If you require a hair drug or alcohol test, our specialization in hair testing means we provide reliable services, with testing centers across every city nationwide capable of conducting these tests. Typically, 1.5 to 2 inches of hair are required from the crown of your head or body for testing. Our hair tests can screen for drugs, alcohol/ETG, or other tailored testing options.
In recent times, drug testing methodologies have increasingly shifted towards hair follicle drug tests. Many employers, judicial systems, and substance abuse experts prefer hair drug tests over conventional urine tests. Employers with zero-tolerance policies, judicial courts, and individuals on probation heavily rely on these tests. One major advantage of hair follicle drug testing is its extended detection period, generally up to 90 days, under an observed collection process, making it almost unfeasible to forge results. Nevertheless, for detecting recent drug use within the past 5 days, urine tests remain the most precise.

Hair testing is recognized as a potent instrument for identifying drug and alcohol consumption. Hair retains a comprehensive history of alcohol and drugs by embedding biomarkers within the fibers of its developing strands. When gathered near the scalp, hair offers a detection window for alcohol and drugs lasting up to three months. Hair collection is straightforward, hard to tamper with, and convenient to transport.
A 1.5-inch hair sample, approximately 200 strands (akin to the thickness of a #2 pencil) closest to the scalp, yields 100mg of hair, optimal for both screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, a 150mg specimen is advisable. We suggest using a jeweler’s scale to weigh the specimen. If scalp hair is unavailable, an equivalent quantity of body hair can be obtained. “Head hair” exclusively denotes scalp hair, while “body hair” encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory procedure for processing a drug test outcome comprises four fundamental phases: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample undergoes initial processing in a laboratory's framework. This step includes ensuring the sample was properly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any additional data entry absent from an electronic chain of custody system.
Screening provides an initial rapid test for abused substances. Though Screening is a cost-efficient method to eliminate drug usage in most samples, a positive screen mandates confirmation for court admissibility. Samples presumptively positive in Screening necessitate a secondary affirmation.
If a Screening stage suggests positive results, more hair is retrieved from the original specimen for Extraction. Here, drugs are extracted from hair at significantly lower concentrations than other methodologies (e.g., urine or oral fluid), underscoring the complexity of performing hair drug screening.
Positive screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Presumptive positive samples are cleansed prior to necessary confirmations. The entire lab procedure from Accessioning to Confirmation is scrutinized under CAP (College of American Pathologists) Hair designation and accreditation as per ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although often termed "hair follicle tests," the analysis targets the hair strand and not the follicle beneath the scalp.

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.
