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 significant method for detecting drug and alcohol consumption. Hair serves as a long-term archive for alcohol and drug use by entrapping biomarkers within the strands of growing hair. When collected near the scalp, hair can offer a detection window of up to around 3 months for alcohol and drugs. Hair is straightforward to gather, relatively hard to tamper with, and simple to transport.
A sample of 1.5 inches consisting of approximately 200 hair strands (comparable to a #2 pencil) closest to the scalp will yield 100mg of hair, which is the optimal sample size for screening and confirmation purposes. For EtG testing, additional analyses, and tests exceeding 10 panels, a specimen amount of 150mg is advised. Using a jeweler’s scale to weigh the specimen is recommended. If scalp hair isn't accessible, a similar amount of body hair is acceptable. "Head hair" refers solely to scalp hair, while "body hair" pertains to all other types like facial or axillary hair.
Process Overview
There are four primary phases in the laboratory processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial processing of a sample into a laboratory’s system. This entails verifying the sample’s proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not supplied by an electronic chain of custody system.
Screening is an initial rapid assessment for drugs of abuse. Even though Screening is a cost-efficient strategy to exclude drug use in most samples, a positive result in Screening needs confirmation to be considered valid in court. Samples that are presumptively positive in Screening require a follow-up confirmation.
If a sample turns out to be presumptively positive during Screening, additional hair is extracted from the initial sample to be prepared for Extraction. Here, drugs are extracted from hair at considerably lower concentrations than in other methods (e.g., urine or oral fluid), making hair drug screening the most challenging procedure to conduct.
Confirmation of any positive screen result is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Any presumptive positive samples undergo washing prior to confirmation if deemed necessary. The entire laboratory process, from Accessioning to Confirmation, is reviewed under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Despite often being termed as "hair follicle tests", the test actually examines the hair strand rather than the hair 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.
