Accredited Drug Testing offers comprehensive hair follicle drug testing services in Collierville, TN. Whether you require a drug or alcohol test, our focus on hair tests is supported by testing centers nationwide, including all cities. Typically, an inch and a half to two inches of head or body hair is needed for testing. Hair analysis can detect drugs, alcohol/ETG, and various other hair testing options.
Recently, hair follicle drug testing has gained popularity as a preferred method. Employers, legal entities, and substance abuse counselors increasingly opt for hair tests over traditional urine tests. Hair tests suit zero-tolerance policies from employers, court orders, or probation requirements because they capture a wider detection window—up to 90 days—and involve an observed and secure process, minimizing cheating opportunities. However, urine tests remain more reliable for detecting recent drug use, typically within the past five days.

Hair analysis is now recognized as an effective method for detecting drug and alcohol consumption. By capturing biomarkers within the strand fibers, hair presents a detailed timeline of substance use. Hair, when cut near the scalp, can offer a detection period of up to 90 days for alcohol and drugs. Collection is straightforward, modifying results is challenging, and it is easy to transport.
A 1.5-inch section of roughly 200 hair strands (similar to the thickness of a #2 pencil) near the scalp yields 100mg of hair, ideal for accurate analysis. For EtG or tests over 10 panels, a collection of 150mg is advisable. Use a jeweler's scale for precise measurement. If scalp hair is lacking, an equivalent body hair amount may be gathered. By head hair, we specifically mean scalp hair; body hair includes other types like facial and axillary hair.
Process Overview
The primary stages in processing a drug test in a lab consist of Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step of integrating a sample into lab records. It entails confirming the sample's secure sealing and accurate shipment, assigning a unique LAN (Laboratory Accessioning Number), and completing necessary data that may not be available from an electronic chain of custody.
Screening is an initial examination for drugs of abuse. Though cost-efficient for excluding drug presence in most samples, a positive outcome in Screening must be confirmed for legal admissibility. Any samples showing a potential positive in Screening mandate further verification.
For samples showing presumption of positivity in Screening, additional hair is processed for Extraction. In this phase, drugs are isolated from hair at lower concentrations compared to alternative methods (e.g., urine or oral fluid), marking hair drug screening as a complex procedure.
Confirmation of any initial positive findings is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo necessary washes before the confirmation step. Every laboratory stage from Accessioning to Confirmation is subject to evaluation under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although commonly termed "hair follicle tests," the evaluation is conducted on the hair strand, not 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.
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. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations.
