Comprehensive hair follicle drug testing is available through Accredited Drug Testing in Holston Valley, Tennessee. If you require a hair-based drug or alcohol test, our facility is equipped for such tests, with centers nationwide. You'll need 1.5 to 2 inches of hair on your head or body for testing. These tests can check for drugs, alcohol/ETG, or other customized options.
Lately, there has been a shift towards using hair follicle drug tests for screening. More and more employers, courts, and substance abuse professionals prefer these over traditional urine tests. Employers who enforce zero-tolerance policies, courts, and probationers commonly use hair tests. The key advantage is the extended detection window of up to 90 days, collected with direct oversight, making it tamper-proof. However, for drugs used within the last 5 days, urine tests are still the gold standard.

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. By capturing biomarkers within the fibers, hair offers a long-lasting record of alcohol and substance use. When gathered near the scalp, it can yield a detection period of up to around 3 months for various substances. Hair collection is straightforward, hard to tamper with, and convenient to transport.
A 1.5-inch segment of roughly 200 hair strands (approximately the diameter of a #2 pencil) closest to the scalp supplies 100mg of hair, which is the optimal amount for analysis and validation. For EtG, additional tests, or those exceeding 10 panels, a 150mg sample is advised. It's recommended to weigh the sample using a jeweler's scale. In the absence of scalp hair, a similar quantity of body hair can be used. Reference to head hair solely pertains to scalp hair. Body hair includes any other types of hair (facial, axillary, etc.).
Process Overview
The drug testing laboratory procedure is composed of four principal stages: Accessioning, Screening, Extraction, and Confirmation.
Initially, Accessioning involves incorporating a sample into the laboratory's framework. This step ensures the sample was correctly sealed and dispatched, allocates a random LAN (Laboratory Accessioning Number), and finalizes data entry not provided by an electronic chain of custody.
The Screening step is a preliminary, swift assessment for substances of abuse. Although it is an economical technique to exclude drug intake for most samples, a positive screen necessitates validation to be permissible in court. Samples that are likely positive in Screening must undergo further confirmation.
Should a sample yield a presumptive positive in Screening, additional hair is extracted from the initial sample for the Extraction phase. During this phase, the extraction of substances from hair occurs at a much lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug analysis the most challenging technique to execute.
The Confirmation of any positive screen is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. Samples identified as presumptively positive are cleaned before confirmation as necessary. The full laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

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.
