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 now recognized as a robust method for identifying drug and alcohol use. Hair captures a prolonged record of alcohol and drugs by embedding biomarkers within the evolving hair strand. When gathered near the scalp, hair can offer up to nearly a 3-month detection window for alcohol and other drugs. Hair is easy to collect, relatively challenging to tamper with, and straightforward to transport.
An ideal sample for examination and verification is a 1.5-inch portion consisting of roughly 200 strands of hair (akin to the thickness of a #2 pencil) nearest to the scalp, amounting to 100mg of hair. For EtG, supplementary panels, and/or panels exceeding 10, a specimen of 150mg is suggested. The specimen should be weighed on a jeweler’s scale. If scalp hair is not present, an equal quantity of body hair can be obtained. By head hair, we mean scalp hair solely. Body hair pertains to all other types of hair (facial, axillary, etc.).
Process Overview
The key stages in lab processing of a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary handling of a sample within a lab’s framework. This encompasses confirming the sample was sealed and dispatched appropriately, designating a random LAN (Laboratory Accessioning Number), and performing any additional data entry absent in an electronic chain of custody system.
Screening entails an initial swift evaluation for abusive drugs. Although Screening is a cost-efficient method to dismiss drug use in most samples, a positive screen must be validated for legal admission. Samples that test presumptively positive in Screening necessitate subsequent confirmation.
Upon a presumptively positive Screening result, more hair is extracted from the initial sample and readied for Extraction. During this phase, drugs are isolated from hair at a significantly lower concentration than with other approaches (e.g., urine or oral fluid), indicating that hair drug testing represents the most challenging method to conduct.
Confirmation of any positive screening conclusion is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The entire lab procedure from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair certification and the compliance with ISO / IEC 17025 standards.

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.
