Accredited Drug Testing provides comprehensive hair follicle testing in Halls Crossroads, Tennessee. If hair drug or alcohol testing is required, we specialize in this area and operate testing centers nationwide, capable of conducting hair tests. You generally need 1.5 to 2 inches of hair from the crown or body. Hair tests can assess drugs, alcohol/ETG, and offer other specialized testing options.
Recently, drug testing increasingly includes hair follicle analysis. Multiple employers, courts, and substance abuse experts favor hair drug tests over urine samples. These tests are essential for employers with zero-tolerance drug policies, courtroom requirements, and those on probation. A major advantage is hair follicle tests' extended detection period, up to 90 days, gathered through observed methods, making them nearly tamper-proof. However, urine tests remain unparalleled for detecting recent drug use within five days.

Hair analysis has emerged as a robust method for identifying drug and alcohol consumption. The hair captures a comprehensive history of substance use by embedding biomarkers in its strands. Collected near the scalp, hair can reveal drug and alcohol use over a period of up to three months. It is easy to gather, challenging to tamper with, and straightforward to transport.
A sample size of 1.5 inches, consisting of roughly 200 hair strands (comparable to the thickness of a #2 pencil), will yield 100mg of hair, which is optimal for analysis. For tests such as EtG, add-ons, and those exceeding 10 panels, 150mg is suggested. It's advisable to weigh the sample using a jeweler's scale. If scalp hair is inaccessible, an equivalent quantity of body hair can be used. In this context, head hair specifically means scalp hair, while body hair encompasses all other types such as facial or axillary hair.
Process Overview
Laboratory processing of drug tests involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is integrated into the lab's system. This step includes checking the sample's seal and shipment integrity, assigning a LAN (Laboratory Accessioning Number), and filling in additional information not captured by an electronic chain of custody system.
Screening is a preliminary assessment for substance use. Although Screening is a cost-efficient method to eliminate the majority of negative samples, a positive requires validation for court admissibility. Samples that test positive initially must undergo a secondary Confirmation.
If a sample tests positive in Screening, additional hair from the initial sample is prepped for Extraction. This phase removes drugs from hair at much lower concentrations than other testing methods like urine or oral fluid, highlighting the complexity of hair drug analysis.
Positive findings from Screening are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before confirmation, all samples presumed positive are washed if necessary. The complete lab process, from Accessioning to Confirmation, adheres to CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Though commonly termed "hair follicle tests," the analysis 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.
