Accredited Drug Testing offers comprehensive hair follicle drug analysis in Underhill, Tennessee. If a hair or alcohol test is required, Accredited Drug Testing excels in hair testing, with centers throughout the nation. A minimum of 1.5 to 2 inches of hair on the head or body is typically necessary. Hair tests can detect drugs, alcohol, or customized testing options.
Recently, hair follicle drug testing has become more prevalent. Employers, courts, and substance abuse professionals often prefer hair drug tests to standard urine tests. Hair follicle tests are favored by those with zero-tolerance policies, judicial systems, and individuals on probation. The extended detection window, up to 90 days, and collected in a supervised process, makes it reliable and hard to tamper with. However, for drug use in the last 5 days, urine tests remain more accurate.

Hair testing is increasingly recognized as an effective means for discovering drug and alcohol consumption. Hair captures a prolonged timeline of alcohol and drug usage by encapsulating biomarkers within the fibers of an elongating hair strand. When trimmed close to the scalp, hair can reveal up to around a 3-month scope for alcohol and drug detection. Hair is easy to gather, not easily tampered with, and readily sent.
A 1.5-inch segment of roughly 200 hair strands (comparable to the diameter of a #2 pencil) taken nearest the scalp will yield 100mg of hair, the optimal amount for both screening and validation. For EtG, additional assessments, and/or examinations beyond 10 panels, 150mg of the sample is advised. We propose using a jeweler’s scale to measure the sample weight. If scalp hair is not present, a similar mass of body hair can be utilized. When mentioning head hair, it pertains solely to scalp hair. Body hair relates to all other hair types (facial, axillary, etc.).
Process Overview
The primary stages in laboratory processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the initial incorporation of a sample into a laboratory's database. This covers ensuring that the sample was properly sealed and transported, allocating a random LAN (Laboratory Accessioning Number), and finalizing any extra data input not available through an electronic chain of custody.
Screening entails a preliminary swift assessment for addictive substances. Although Screening offers a cost-efficient method to negate drug use for most specimens, a positive screen necessitates confirmation to be valid in judicial settings. Samples tentatively positive during Screening demand subsequent confirmation.
When a sample shows presumptive positivity in the Screening phase, extra hair is extracted from the original batch for Extraction preparation. At this junction, drugs are drawn from hair at significantly diminished concentrations compared to other techniques (e.g., urine or oral fluid), underlining why hair drug screenings are demanding to execute.
Verification of any positive screening outcome is implemented using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed prior to confirmation as required. The entire lab journey from Accessioning to Confirmation aligns with both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

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.
