Accredited Drug Testing offers comprehensive hair follicle drug screening in Oak Grove, Tennessee. If you require a drug or alcohol test involving hair, Accredited Drug Testing is proficient in hair assessments, with facilities Nationwide ready to conduct testing. Typically, 1.5 to 2 inches of head or body hair is needed for testing. Hair analysis can detect drugs, alcohol/ETG, or be tailored for different options.
In recent times, a hair follicle drug test has been increasingly used for drug screening. A growing number of employers, judicial systems, and substance abuse experts now prefer a hair drug test over traditional urine tests. Hair follicle tests are favored by workplaces with strict no-drug policies, courts, and those overseeing probation cases, owing to their extended 90-day detection window, direct observation collection method, and difficulty in manipulation. Nevertheless, for recent drug use within 5 days, urine tests remain the most precise choice.

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged history of these substances by embedding biomarkers within the fibers of its growing strands. When taken from close to the scalp, hair can provide around a 3-month detection period for alcohol and various drugs. Hair is straightforward to collect, somewhat challenging to adulterate, and conveniently shipped.
A sample measuring 1.5 inches, containing roughly 200 hair strands (comparable to the width of a #2 pencil) from the scalp can yield 100mg of hair, which is the optimal sample size for screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, a specimen of 150mg is advisable. We suggest using a jeweler’s scale for accurate weighing. If scalp hair is not available, a similar quantity of body hair may be used. References to head hair pertain solely to scalp hair, while body hair encompasses all other types (such as facial or axillary hair).
Process Overview
The laboratory processes associated with a drug test outcome entail four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning focuses on the initial incorporation of a sample into a laboratory's system. This process includes verifying proper sealing and shipping of the sample, assigning it a random LAN (Laboratory Accessioning Number), and completing any data entry that is not done via an electronic chain of custody system.
Screening is a preliminary rapid assessment for traces of drug misuse. Though Screening offers a cost-effective means to eliminate drug usage in many samples, any positive result necessitates confirmation for legal admissibility. Samples showing presumptive positives in Screening must undergo further confirmation.
If Screening suggests a positive result, additional hair is extracted from the initial sample and readied for Extraction. This stage involves the low-concentration extraction of drugs from hair, unlike other methods (e.g., urine or oral fluid), which is why hair drug analysis is the most complex to execute.
Confirmation follows any positive Screening result through methods such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are washed before confirmation, as needed. The complete laboratory procedure, from Accessioning to Confirmation, is scrutinized under both CAP (College of American Pathologists) Hair guidelines and ISO/IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although commonly called "hair follicle tests", the test targets the hair strand and not the follicle itself 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.
