Accredited Drug Testing offers comprehensive hair follicle drug tests in Brentwood, Tennessee. If you're in need of a hair drug or alcohol test, our expertise lies in hair testing, with facilities available in every major city across the country to conduct such tests. Generally, at least 1.5 to 2 inches of hair from your head or body can be used. Hair tests can detect drugs, alcohol/ETG, and support other specialized testing requirements.
Lately, hair follicle drug tests have gained popularity over other testing methods. Employers, judicial systems, and substance abuse specialists often prefer hair drug tests to standard urine tests. Those with zero-tolerance for drug use, such as employers, judicial bodies, and probationary programs, are adopting this method. The chief advantage of hair follicle tests is their extended detection window—up to 90 days—and their resistance to tampering, although urine tests remain the gold standard for drug use detection within the past five days.

Hair examinations have emerged as a significant approach for identifying substance use. Hair records a prolonged timeline of alcohol and drug intake by embedding biomarkers within its fibers as it grows. When gathered near the scalp, it offers approximately a three-month detection period for alcohol and drugs. Collecting hair is straightforward, less prone to tampering, and easy to transport.
A 1.5-inch segment consisting of around 200 hair strands (comparable in size to a #2 pencil) close to the scalp yields 100mg of hair, which is ideal for both screening and confirmation. For EtG, additional tests, and/or those surpassing 10 panels, it’s suggested to use 150mg of the sample. It's advisable to weigh the hair sample using a jeweler’s scale. If scalp hair is not an option, an equivalent quantity of body hair can be used. When the term head hair is used, it specifically indicates scalp hair. Body hair pertains to other varieties (facial, underarm, etc.).
Process Overview
There are four crucial stages in processing drug test results in the lab: Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, a sample is initially processed into the laboratory's system. This process ensures the sample is properly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data input not covered by an electronic chain of custody system.
Screening provides a quick preliminary test for substance abuse. Although Screening is a cost-efficient method to rule out drug use for most samples, following up with confirmation is essential for legal admissibility. Any samples that presumptively test positive during Screening must undergo a secondary confirmation.
Upon a presumptive positive result in Screening, more hair is extracted from the primary sample for the Extraction stage. Here, drugs are extracted from hair at a much lower concentration compared to other methodologies (such as urine or oral fluid), highlighting the complexity of performing hair drug screening.
GC/MS, GC/MS/MS, or LC/MS/MS methods handle the Confirmation of any positive screening outcomes. Prior to confirmation, any samples with presumptive positive results are washed as necessary. The entire process, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair standards and accredited to ISO / IEC 17025 standards.

Note: The term "hair follicle tests" is often used, but the analysis is conducted on the hair strand rather than 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.
