The hair follicle drug test method has become more prevalent for drug testing in recent years. Numerous employers, courts, and Substance Abuse professionals opt for hair drug tests over conventional urine tests. Employers with strict drug-use policies, courts, and probationary individuals favor hair follicle drug tests due to their prolonged drug detection window, typically up to 90 days, conducted under observation, making tampering nearly impossible. Nonetheless, for recent usage within five days, urine tests remain the most accurate measure.

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 tests are recognized as influential means for detecting drug and alcohol consumption. Hair offers a prolonged timeline of drug and alcohol intake by capturing biomarkers within its strands as they grow. When retrieved near the scalp, hair can reveal alcohol and drug use for roughly a 3-month span. Hair samples are easy to obtain, quite tough to tamper with, and straightforward to transport.
A 1.5-inch snippet consisting of approximately 200 hair strands (comparable in thickness to a #2 pencil) from the scalp provides 100mg of hair, which is ideal for both screening and confirmation tests. For EtG and additional panels exceeding 10, 150mg is suggested. It's best practice to use a jeweler’s scale for weighing the sample. Should scalp hair be lacking, a comparable amount of body hair can be used. When mentioning head hair, we exclusively imply scalp hair. Body hair encompasses all other types (such as facial, axillary, etc.).
Process Overview
The drug test result processing in the lab consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step where a sample is entered into a laboratory's system. It ensures the sample's seal and shipment were proper, assigns a random LAN (Laboratory Accessioning Number), and fills any extra information not included by an electronic chain of custody system.
Screening performs a preliminary quick assessment for drug abuse. Although screening is a budget-friendly method to exclude drug use for most samples, a positive indication requires confirmation for court validity. Samples testing presumptively positive during Screening need further confirmation.
If a sample registers presumptively positive at the Screening phase, more hair is extracted from the initial batch and ready for Extraction. Here, drug concentrations are drawn from hair significantly lower than via other methods (like urine or oral fluid), thereby making hair drug tests the most challenging method to execute.
Confirmation of any positive screen outcomes occurs through GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples showing presumptive positives are cleaned as needed before confirmation. From Accessioning to Confirmation, the entire laboratory workflow is overseen according to both the CAP (College of American Pathologists) Hair specifications and ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Despite often being termed "hair follicle tests," the evaluation focuses on the hair strand and not the follicle within the scalp.
The preference for hair testing over urine testing in Spencer, TN, stems from its manifold benefits. Hair tests surpass traditional urine tests by offering superior detection accuracy and reliability. Unlike urine tests with a limited detection window, hair testing provides a broader scope with up to a 90-day insight into drug use, reflecting a user’s long-term substance history, which is invaluable for comprehensive evaluations.
One of the primary advantages of hair follicle testing in Spencer, TN, is its extended detection window.

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.
