Accredited Drug Testing offers thorough hair follicle drug testing in Westel, Tennessee. Whether you require a hair drug or alcohol test, Accredited Drug Testing is an expert in hair testing, with centers available nationwide, including every city, that can conduct a hair test. Typically, 1.5 to 2 inches of hair from the crown or body are needed. Hair tests can identify drugs, alcohol/ETG, or be customized for other purposes.
Recently, using a hair follicle drug test has become more common for drug testing. Many employers, courts, and Substance Abuse experts are preferring hair drug tests over standard urine tests. Hair follicle tests are favored by employers with strict no-drug policies, courts, and probation cases. These tests offer an extended drug use detection period, usually up to 90 days, with observation during collection, making cheating nearly impossible. Urine tests, however, are still deemed most accurate for drug use detection within the past 5 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 testing has emerged as a robust method for identifying drug and alcohol consumption. By embedding biomarkers within the fibers of growing hair, it offers an extensive record of alcohol and drug use. Hair samples taken close to the scalp can reveal a substance presence window of up to 3 months. Hair collection is straightforward, challenging to tamper with, and simple to transport.
A 1.5-inch sample consisting of roughly 200 hair strands (approximating the size of a #2 pencil) nearest to the scalp equates to 100mg, which is the optimal amount for both screening and confirmation tests. For EtG, add-ons, or tests exceeding 10 panels, 150mg of hair is advised. We suggest using a jeweler’s scale for weighing. In the absence of scalp hair, a comparable amount of body hair can be gathered. The term head hair denotes only scalp hair, while body hair covers all other types (facial, axillary, etc.).
Process Overview
The procedure for lab processing a drug test result comprises four major phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning begins with incorporating a sample into the laboratory’s system, ensuring that it was sealed and shipped correctly, assigning a random Laboratory Accessioning Number (LAN), and completing any additional necessary data entry absent in an electronic chain of custody system.
Screening offers an initial quick assessment for substances of abuse. While it's a cost-efficient technique to identify drug use in most samples, any positive screens demand confirmation to be valid for legal proceedings. Samples that display presumptive positivity in Screening do require further confirmation.
If a sample exhibits presumptive positivity during Screening, additional hair is extracted from the initial sample and prepped for Extraction. Here, drugs are isolated from the hair in much lower concentrations compared to other methods (i.e., urine or oral fluids), contributing to the complexity of hair drug screening implementation.
Positive Screening results are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivity undergo washing before confirmation as necessary. The complete laboratory protocol from Accessioning to Confirmation undergoes scrutiny under the CAP (College of American Pathologists) Hair designation and follows ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Though commonly termed as "hair follicle tests", this assessment inspects the hair strand, not the scalp's 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. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations.
