Accredited Drug Testing offers comprehensive hair follicle drug assessments in Walnut Grove, Tennessee. Whether your need is for drug or alcohol testing via hair samples, we are experts in hair analysis, with testing facilities located across all cities in the U.S. A minimum of 1.5 to 2 inches of hair from the scalp or body is typically required. Drug, alcohol/ETG, or other specialized hair evaluations can be conducted through hair analysis.
The use of hair follicle drug testing in recent years has been on the rise. Many workplaces, judicial systems, and Substance Abuse authorities are opting for hair tests over traditional urine ones. Hair tests are favored by employers with stringent drug policies, legal entities, and probation officers. The key advantage of hair tests is the extended detection period of about 90 days, with collection under supervision, thus making it hard to tamper. However, urine tests remain the preferred choice for detecting recent drug use within the first 5 days.

Hair analysis has emerged as a significant method for identifying drug and alcohol consumption. Hair strands can archive an extended history of substance use by encapsulating biomarkers within the fibers of hair as it grows. When obtained near the scalp, hair offers an approximate detection period of up to 90 days for alcohol and other drugs. Collection is straightforward, the likelihood of tampering is low, and shipping is efficient.
A sample of 1.5 inches consisting of roughly 200 hair strands (equivalent to the width of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal amount for testing and validation. For EtG, additional tests, and tests exceeding 10 panels, 150mg is advisable. Using a jeweler’s scale for measurement is suggested. If scalp hair is scarce, an equivalent quantity of body hair can be used. When discussing head hair, it exclusively refers to scalp hair. Conversely, body hair encompasses all other types such as facial and axillary hair.
Process Overview
In hair testing, the primary steps are Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial integration of the sample into the laboratory’s processing system. This step ensures the sample was properly sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and completes any outstanding data entry absent from electronic custody systems.
Screening entails an initial rapid assessment for substances of abuse. It is an economical approach to preliminarily eliminate drug use from most samples, but a positive screen needs verification to hold up in legal circumstances. Presumptively positive screens necessitate additional validation.
Should a sample prove presumptively positive during Screening, more hair from the original sample is gathered for Preparation and Extraction. Drugs are extracted from hair at lower concentrations than other methods (e.g., urine or oral fluid), which elevates the complexity of hair drug screening.
Positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS procedures. Presumptive positives undergo a wash prior to Confirmation. The complete laboratory process from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: The term "hair follicle tests" is often used, but the analysis is conducted on the hair strand itself, not the follicle beneath the scalp.

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.
