Accredited Drug Testing offers thorough hair follicle drug testing in Harriman, Tennessee. If you're seeking a hair drug or alcohol test, we specialize in hair testing with centers nationwide that can conduct a hair test. Typically, 1.5 to 2 inches of hair from the head or body is needed. Hair tests can be examined for drugs, alcohol/ETG, or other personalized hair testing choices.
In recent years, drug testing methods have increasingly included hair follicle drug tests. Many employers, courts, and Substance Abuse experts demand a hair drug test rather than a typical urine test. Hair follicle drug tests are favored by employers with zero-tolerance drug policies, courts, and probation individuals. The key advantage of hair follicle drug testing is its longer drug detection window, usually up to 90 days, gathered through an observed process, making it hard to deceive. However, to test recent drug use within 5 days, the urine test remains the most precise option.

The utilization of hair testing has gained recognition as an effective method for identifying drug and alcohol consumption. Hair retains a prolonged timeline of alcohol and drug intake by embedding biomarkers within the strands as they grow. When hair is gathered close to the scalp, it can offer up to a three-month detection period for alcohol and drugs. Collecting hair is straightforward, difficult to tamper with, and easily transportable.
Obtaining a 1.5-inch segment comprising around 200 hair strands (roughly equivalent to a #2 pencil) nearest to the scalp yields 100mg of hair, which is optimal for both screening and confirmation. For EtG, enhancements, and/or analyses exceeding 10 panels, a 150mg sample is advisable. For accurate measurement, we suggest using a jeweler's scale to weigh the specimen. In cases where scalp hair is inaccessible, the collection of a comparable amount of body hair is permissible. When we reference head hair, it exclusively implies scalp hair, whereas body hair denotes all other varieties (facial, armpit, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four principal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary procedure of incorporating a sample into a laboratory's framework. This step includes ensuring proper sealing and transportation of the sample, allocating a unique LAN (Laboratory Accessioning Number), and supplementing any ancillary data entry not supplied by an electronic chain of custody system.
Screening consists of an initial rapid assessment for drugs. Though Screening is a budget-friendly approach to exclude drug usage in the majority of samples, a positive result in screening necessitates confirmation for legal reliability. Presumptively positive samples from Screening must undergo further validation.
Should a sample yield a presumptive positive in the Screening phase, additional hair is extracted from the original sample and readied for Extraction. In this phase, drugs are extracted from hair at significantly minimized concentrations than in other methodologies (e.g., urine or oral fluids), rendering hair drug screening as one of the most intricate methodologies to execute.
Positive screening results undergo confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples receive washing prior to confirmation if required. The entire laboratory process from Accessioning to Confirmation is reviewed under the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly deemed as "hair follicle tests," the analysis targets the hair strand rather than the 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.
