In Nashville, Tennessee, Accredited Drug Testing offers full-service hair follicle drug testing. For those requiring hair drug or alcohol assessments, our expertise is in hair testing, with nationwide centers capable of conducting these evaluations. Typically, 1.5 to 2 inches of hair either from the crown or body is essential. Our hair tests analyze drugs, alcohol/ETG, or other tailored options.
Recently, drug testing methods have shifted towards hair follicle tests more often. Increasingly, employers, judicial systems, and substance abuse specialists are favoring this method over urine tests. Employers with strict anti-drug policies, courts, and probation officers use hair tests for their extended 90-day detection period, observed collection, and difficulty to tamper with. However, urine tests remain more reliable for detecting recent drug use 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 is now perceived as an effective method for identifying drug and alcohol consumption. It offers a comprehensive record of drug and alcohol usage as hair retains biomarkers within its fibers as it grows. If gathered near the scalp, hair can reveal drug and alcohol consumption history for a span of roughly 90 days. The collection of hair is straightforward, relatively resistant to tampering, and easy to transport.
A sample measuring 1.5 inches, consisting of approximately 200 strands (comparable to the thickness of a #2 pencil) near the scalp, will amount to 100mg, which is the optimal sample size for both screening and confirmation processes. For tests involving EtG, additional testing, or those exceeding 10 panels, a 150mg sample is advisable. Using a jeweler's scale to measure the sample weight is recommended. Should scalp hair be unavailable, a comparable volume of body hair can be collected. References to head hair specifically mean scalp hair. Body hair pertains to any other types such as facial or axillary hair.
Process Overview
There are four critical steps in the laboratory's analysis of a drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning deals with the primary integration of a sample into the lab's system, ensuring the sample’s integrity in sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and filling in any missing data not supplied by electronic tracking systems.
Screening entails an initial swift examination for controlled substances. Although Screening is economically efficient for ruling out drug presence in most samples, court admissibility requires confirmation of a positive screening result. Samples showing presumptive positivity in Screening will need further confirmation.
When a sample shows presumptive positivity during Screening, additional hair is withdrawn from the sample and readied for Extraction. In Extraction, drugs are isolated from hair at much lower concentrations than in other methods (such as urine or saliva), making hair testing a highly challenging methodology.
The Confirmation of any positive Screening result uses GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before Confirmation when necessary. The complete lab procedure from Accessioning to Confirmation undergoes review according to both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

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.
