In Grantfork, Illinois, Accredited Drug Testing offers all-inclusive hair follicle drug testing. If a hair or alcohol test is required, our centers Nationwide, specializing in hair analysis, can assist. Typically, 1.5 to 2 inches of hair from the head or body is needed. Hair analysis can determine the presence of drugs, alcohol/ETG, or other specific tests.
Recently, hair follicle testing has become more common in substance testing methodologies. Employers, judicial systems, and substance abuse experts are favoring hair testing over urine samples. This method benefits from an extended drug detection window of up to 90 days, is collected under supervision, and is difficult to tamper with. However, for substances consumed in the last 5 days, urine testing remains superior.

Hair assessments have gained recognition as an effective means of identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and drug exposure by capturing biomarkers within the strands in growth. When taken from near the scalp, hair can reveal drug and alcohol use for around a three-month period. The process of hair collection is straightforward, challenging to tamper with, and simple to transport.
A sample of 1.5 inches, comprising approximately 200 hair strands (comparable in size to a #2 pencil) from closest to the scalp, provides 100mg of hair, which is perfect for analysis and confirmation. For EtG, specific add-ons, or tests exceeding 10 panels, a 150mg sample is preferred. Measuring the sample on a jeweler’s scale is advised. If scalp hair is unavailable, a comparable amount of body hair is acceptable. References to head hair indicate exclusively scalp hair, whereas body hair signifies all other types (e.g., facial, axillary).
Process Overview
The laboratory processing of drug test outcomes involves four major steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the introductory processing of a sample into a laboratory’s system, including the confirmation of proper sealing and shipping, the assignment of a unique LAN (Laboratory Accessioning Number), and the completion of any supplemental data input omitted by an electronic chain of custody system.
Screening pertains to an initial and rapid assessment for drug misuse. Though Screening is an economical approach to exclude drug use in most cases, a positive finding necessitates confirmation for legal acceptability. All samples flagged as presumptively positive during Screening require secondary validation.
When a sample turns presumptively positive in Screening, additional hair is extracted from the initial sample and readied for Extraction. This phase involves extracting drugs from hair at considerably lower concentrations than other methods (e.g., urine or oral fluid), highlighting why hair drug analysis is exceptionally challenging.
The Confirmation of any positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Each presumptively positive sample undergoes cleaning before confirmation, as needed. The entire lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

Note: While commonly labeled as "hair follicle tests", the examination targets the hair strand, 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. 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.
