Offering specialized hair and alcohol testing, our centers are present across all major cities in the USA. Adequate hair length required is 1.5 to 2 inches from your head or body hair. These tests are designed to detect drugs or alcohol/ETG along with other customized testing solutions.
Hair follicle drug testing has become a more prevalent method for drug testing. Many employers, courts, and substance abuse experts now prefer hair drug tests over traditional urine tests. People under probation, and zero-tolerance workplaces, often rely on these tests. The most significant advantage is its extensive detection period, approximately 90 days, under supervised collection making it very challenging to falsify. However, urine tests remain precise for detecting recent drug use within five days.

Hair analysis is perceived as an effective strategy for identifying alcohol and drug usage. The hair captures a prolonged record of such substances by holding biomarkers within the strands as they grow. When gathered near the scalp, hair offers nearly a 90-day detection period for alcohol and other substances. This method is easy to gather, hard to falsify, and convenient to transport.
A sample measuring 1.5 inches containing roughly 200 hair strands (similar in thickness to a #2 pencil) nearest to the scalp provides 100mg of hair, which is ideal for both screening and confirmation. For EtG, additional tests, and/or those exceeding 10 panels, 150mg is advised. It's preferable to weigh the sample on a jeweler's scale. If scalp hair is not available, an equivalent amount of body hair is an alternative. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Summary
Four key stages in the laboratory processing of drug test outcomes include Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts with the sample's initial processing into a lab's system. It involves verifying correctly sealed and shipped samples, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry that an electronic chain of custody system might miss.
Screening constitutes an initial rapid assessment for drugs of abuse. Although Screening is economical to exclude drug use in most samples, a positive screen requires confirmation for legal admissibility. Presumptively positive samples in Screening necessitate secondary confirmation.
For samples indicated as positive during the Screening stage, additional hair is extracted from the primary specimen for Extraction. Here, drugs are removed from hair in much lower concentrations than other methods (e.g., urine or oral fluid), which makes hair drug testing the most challenging method to execute.
Any positive results from Screening are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, presumptive positive samples are cleaned as needed. The entire laboratory process, from Accessioning to Confirmation, falls under the review of CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
Benefits of hair drug testing:
Challenges:
Note: Often dubbed "hair follicle tests," the test actually examines the hair strand rather than the follicle under 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.
