In Parker Crossroads, Tennessee, Accredited Drug Testing offers comprehensive hair follicle drug testing solutions. Our expertise lies in conducting hair tests, with facilities available throughout the nation to carry out these assessments. Generally, at least 1.5 to 2 inches of hair from the crown or body is required. These tests are capable of detecting drugs, alcohol/ETG, or tailored testing preferences.
Hair follicle drug testing has become a prevailing method for identifying substance use. Employers with strict anti-drug policies, as well as legal and rehabilitation professionals, often prefer this over traditional urine tests. Its key advantage is an extensive detection window, typically covering up to 90 days, collected through a supervised process, minimizing the chance of falsification. However, urine tests remain dependable for detecting recent use within five days.

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 analysis is increasingly viewed as an effective means to identify drug and alcohol consumption. Hair retains a chronological record of alcohol and other drug usage, capturing biomarkers within the hair strands as they grow. When sourced near the scalp, hair can reveal drug or alcohol intake over a span of roughly three months. The collection process is straightforward, making it somewhat resistant to tampering and easy to transport.
A sample typically involves a 1.5-inch section consisting of approximately 200 hair strands (with a thickness akin to a #2 pencil) nearest the scalp, equating to 100mg of hair, which is optimal for both screening and verification processes. For EtG, supplementary tests, or panels exceeding ten categories, a sample size of 150mg is advised. It's essential to weigh the sample using a jeweler's scale. If head hair is not accessible, equivalent quantities of body hair can be gathered. The term "head hair" specifically references scalp hair, whereas "body hair" encompasses all other types (like facial or underarm hair).
Process Overview
The key stages in laboratory testing of a drug sample include Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the sample's initial system entry in the lab. This process involves ensuring the sample was correctly sealed and sent, assigning a unique LAN (Laboratory Accessioning Number), and fulfilling any outstanding data entries absent from an electronic chain of custody.
Screening serves as a preliminary examination for drugs of abuse. While it's a cost-effective method for excluding drug presence in most samples, positive screenings need further verification for legal recognition. Samples testing positive during Screening necessitate another confirmation phase.
For samples with initial positive results in Screening, additional hair is extracted from the main sample and readied for Extraction. Here, drugs are isolated from hair at significantly diminished concentration rates compared to alternate techniques (such as those involving urine or oral fluid), underscoring the complexity of hair drug screening.
For validation of any positive screening outcomes, processes like GC/MS, GC/MS/MS, or LC/MS/MS are utilized. Presumptive positive specimens undergo necessary washing before confirmation. The full lab sequence, spanning from Accessioning to Confirmation, is scrutinized in line with the CAP (College of American Pathologists) Hair criteria and certified per ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Though frequently denoted as "hair follicle tests", this procedure examines the hair strand rather than the sub-scalp hair follicle.

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.
