Accredited Drug Testing provides comprehensive hair follicle drug tests in Dixon, Illinois. If you are in need of a hair drug or alcohol test, our specialization in hair testing is supported by nationwide testing centers, including all cities. A minimum of 1.5 to 2 inches of hair, whether from the crown or the body, is generally required. Tests can check for drugs, alcohol/ETG, or be tailored for unique hair testing needs.
The trend toward hair follicle drug testing has grown in recent years. More employers, legal authorities, and substance abuse experts prefer it over urine testing. Hair tests are chosen by those enforcing strict drug use policies, legal systems, and probation services. A key advantage is its extended detection period of up to 90 days, observed during collection, making tampering very difficult. Despite this, urine tests remain most accurate for detecting recent drug use within five days.

Hair analysis has emerged as a robust method for detecting drug and alcohol consumption. Hair strands offer a long-term record of substance use by capturing biomarkers within the fibers as the hair grows. When taken near the scalp, hair can offer up to roughly a 3-month detection timeline for substances. Hair is easy to gather, fairly challenging to tamper with, and simple to send.
A 1.5-inch section of about 200 hair strands (approximately the diameter of a #2 pencil) from the scalp provides 100mg of hair, the perfect sample for screening and verification. For EtG, additional tests, and/or assessments beyond 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale to weigh the sample. If scalp hair isn't accessible, a similar quantity of body hair can be used. When mentioning head hair, we mean scalp hair exclusively. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The four essential phases in the laboratory analysis of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the foundational handling of a specimen into a lab’s database. This process ensures the sample was sealed and dispatched correctly, allocates a random LAN (Laboratory Accessioning Number), and finalizes any supplementary data input not supplied by an electronic chain of custody system.
Screening is a preliminary rapid assessment for illicit substances. While it is an economical method to rule out drug usage on most samples, a favorable screen requires confirmation for admittance in legal proceedings. Any samples that test presumptively positive in Screening must undergo a secondary verification.
If a sample emerges presumptively positive during Screening, additional hair is extracted from the primary sample and processed for Extraction. At this stage, drugs are separated from hair at a significantly lower concentration than other methods (e.g., urine or oral fluid), which makes hair drug screening the most complex method to execute.
Confirmation for any positive screening result is done via GC/MS, GC/MS/MS or LC/MS/MS. All presumptively positive samples undergo washing prior to confirmation as necessary. The comprehensive lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although often called "hair follicle tests", the analysis itself examines 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.
