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 testing is considered a strong method for identifying drug and alcohol consumption. Hair captures a historical record of alcohol and substances by incorporating biomarkers in its growing fibers. When gathered near the scalp, hair delivers about a 3-month detection period for alcohol and substances. Hair is easy to obtain, relatively hard to tamper with, and simple to transport.
A 1.5-inch piece of roughly 200 hair strands (comparable to the size of a #2 pencil) closest to the scalp produces 100mg, the perfect sample for analysis and verification. For EtG, supplementary tests, and/or panels beyond 10 testing zones, 150mg of the sample is advisable. We suggest measuring the sample with a jeweler’s scale. If scalp hair isn't available, a similar amount of body hair can be used. When we mention head hair, we refer specifically to scalp hair. Body hair includes all other types, such as facial or axillary hair.
Process Overview
The key steps in processing a drug test in the lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves entering a sample into a lab’s system, ensuring the sample was correctly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data entry beyond the electronic chain of custody system.
Screening offers a preliminary evaluation for substance abuse. While Screening efficiently excludes drug use in most samples, a positive result requires confirmation for legal admissibility. Samples with a presumptive positive in Screening need further confirmation.
When a sample shows a presumptive positive in Screening, additional hair is extracted from the initial sample for Extraction. Here, drugs are extracted at a lower concentration than other methods (like urine or oral fluids), enhancing the challenge of hair drug testing methodology.
Any positive result in Screening undergoes Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positives are cleansed before necessary confirmations. The whole 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.

Note: Despite being called "hair follicle tests", the examination focuses on the hair strand, not the follicle below 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.
