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 regarded as an effective method for identifying drug and alcohol consumption. Hair provides a prolonged record of alcohol and drugs by embedding biomarkers in the hair strand's fibers as it grows. When taken near the scalp, hair can reveal a detection window for up to about 3 months for alcohol and drugs. Hair collection is straightforward, fairly hard to tamper with, and convenient to transport.
A 1.5-inch segment of approximately 200 hair strands (roughly the dimension of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal amount for evaluation and validation. For EtG, add-ons, and/or panels exceeding 10, 150mg of the sample is advisable. It is suggested to weigh the sample using a jeweler’s scale. Should scalp hair be absent, an equivalent quantity of body hair may be gathered. When mentioning head hair, it pertains exclusively to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the initial handling of a sample into a lab's system. This step verifies that the sample was properly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and finalizes any additional data entry absent from an electronic chain of custody system.
Screening entails an initial swift check for drug abuse. Screening serves as a cost-efficient measure to negate drug usage in most samples, but a positive screening requires confirmation to be court-admissible. Samples that are preliminarily positive in Screening necessitate subsequent confirmation.
Should a sample be preliminarily positive during the Screening phase, additional hair is retrieved from the initial sample and prepped for Extraction. In this process, drugs are extracted from hair at concentrations lower than those found in other methods (such as urine or oral fluid), highlighting hair drug screening as a challenging method to execute.
Confirmation of any positive screening is undertaken via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation, as required. The complete lab procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly termed "hair follicle tests", the analysis is performed on the hair strand rather than the hair follicle beneath the scalp.
For Lake Tahoe residents, hair follicle testing outperforms traditional urine tests. Unlike urine tests, which are limited to recent use, hair testing offers a longer detection period and greater accuracy. This method minimizes false results and enhances reliability, ensuring a clear report of substance use history.
Hair follicle testing provides an unmatched advantage with its extensive detection window reaching up to 90 days, enabling employers in Lake Tahoe to obtain an in-depth review of drug use history. This long-term visibility helps in making informed hiring and monitoring decisions.

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.
