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 analysis is recognized as an effective method for identifying drug and alcohol consumption. It offers a comprehensive timeline of substance use by retaining biomarkers within the fibers of growing hair strands. When collected near the scalp, hair provides a detection period of up to roughly three months for both alcohol and other drugs. Collection is straightforward, tampering is challenging, and transportation is convenient.
A sample length of 1.5 inches containing roughly 200 hair strands (approximately the diameter of a #2 pencil) near the scalp yields 100mg of hair, the optimal quantity for both initial and confirmatory testing. For EtG, additional components, and tests exceeding 10 panels, 150mg of the sample is advisable. It is recommended to weigh the sample using a jeweler’s scale. Should scalp hair be unavailable, a similar amount of body hair can be utilized. References to head hair pertain solely to scalp hair, whereas body hair encompasses other types (such as facial, axillary, etc.).
Process Overview
The laboratory procedure for processing drug test outcomes consists of four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary integration of a sample into the laboratory’s system. This phase includes confirming that the sample was properly sealed and sent, allotting a unique LAN (Laboratory Accessioning Number), and fulfilling any extra data entry not facilitated by an electronic chain of custody system.
Screening involves a preliminary rapid assessment for substances of abuse. Screening is a cost-efficient approach to exclude drug usage in most samples; however, a positive screen must be verified for legal eligibility. Any samples showing presumptive positive results during Screening require additional confirmation.
When a sample shows a presumptive positive at the Screening phase, more hair is extracted from the initial sample and prepped for Extraction. During Extraction, substances are isolated from hair at considerably lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most complex methodology.
Verification of any positive screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives are cleansed before verification as needed. The full laboratory procedure from Accessioning to Confirmation is reviewed in accordance with both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards.

Note: Often termed as "hair follicle tests", the test examines 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. 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.
