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 recognized as an effective method for identifying drug and alcohol consumption. The hair provides an extended timeline of substance use by locking biomarkers in the fibers of the hair as it grows. When obtained near the scalp, hair can reveal a detection period of up to around three months for alcohol and drugs. The collection of hair is straightforward, relatively challenging to tamper with, and convenient to transport.
A sample of 1.5 inches, which consists of approximately 200 hair strands (akin to the thickness of a #2 pencil) nearest to the scalp, offers 100mg of hair, the optimal amount for screening and confirmation. For EtG, additional tests, or tests exceeding 10 panels, it is advisable to have 150mg of the specimen. It's recommended to measure the specimen using a jeweler’s scale. If scalp hair cannot be obtained, a comparable amount of body hair may be used. "Head hair" signifies only scalp hair, while "body hair" encompasses all other types (such as facial, axillary, etc.).
Process Overview
The lab processing of a drug test sample involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab’s system. This process involves confirming that the sample was properly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry absent in an electronic chain of custody system.
Screening conducts an initial rapid assessment for drug presence. While it is an economical method to negate drug use in most samples, any positive screen must be confirmed for court admissibility. Samples presumed positive in Screening necessitate a secondary confirmation.
If a sample shows a presumptive positive in the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. This phase involves extracting drugs from hair at concentrations considerably lower than other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.
Confirmation of positive screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing before confirmation if needed. The comprehensive lab process, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair designation and accreditation standards of ISO / IEC 17025.
Advantages of hair drug testing:
Limitations:
Note: Although often termed "hair follicle tests," the test examines the hair strand itself, 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.
