For comprehensive hair follicle drug testing in Kingston, Tennessee, turn to Accredited Drug Testing. If a hair drug or alcohol examination is necessary, we excel in hair assessments with testing centers available Nationwide. Typically, you need 1.5 to 2 inches of hair from the head or body for the test. Our hair analysis can screen for drugs, alcohol/ETG, or be customized as needed.
Hair follicle drug tests have become more common for drug testing in recent years. Employers, courts, and Substance Abuse professionals often request these over traditional urine tests. They are favored by employers with zero-tolerance policies, the judicial system, and for those on probation. Hair tests offer a superior detection window of up to 90 days, are conducted under supervision, and are hard to manipulate. However, a urine test remains the standard for detecting drug use within the previous 5 days.

Hair sampling is recognized as an effective method for identifying drug and alcohol usage. The composition of hair captures biomarkers within the fibers as it grows, offering an extended timeline of substance consumption. When cut near the head, hair can reveal evidence of alcohol and drug use for roughly up to three months. Its collection is straightforward, hard to alter, and simple to transport.
A sample measuring 1.5 inches with around 200 hair strands (approximately the diameter of a #2 pencil) closest to the head yields 100mg, deemed the optimal amount for both screening and confirmation. For EtG, additional requests, or tests exceeding 10 panels, 150mg of hair specimen is suggested. Using a jeweler’s scale is advised for measuring the sample. If head hair is missing, a similar quantity of body hair might be gathered. When addressing head hair, it specifically means scalp hair. Meanwhile, body hair encompasses all other varieties (like facial, axillary, etc.).
Process Overview
The four key phases in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the sample's preliminary processing into the lab system. This process involves ensuring the sample's proper sealing and shipment, allocating a random LAN (Laboratory Accessioning Number), and fulfilling any extra data input missing from an electronic chain of custody system.
Screening provides a preliminary rapid assessment for substance abuse. Although Screening is a cost-efficient method to exclude drug exposure in most samples, a positive result needs confirmation to be court-admissible. Samples presumed positive in Screening necessitate a secondary affirmation.
In cases of a presumptive positive during the Screening phase, additional hair from the initial sample is prepared for Extraction. In this step, substance extraction from hair occurs at a significantly lower concentration than alternative methods (such as urine or oral fluid), highlighting why hair drug screening is a challenging approach.
Positive screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleaned before confirmation if required. The overall laboratory journey, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 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.
