At Accredited Drug Testing, we offer comprehensive hair follicle drug testing services in Big Barren Creek, Tennessee. Whether you're in need of a drug or alcohol test via hair sample, we're the experts in hair testing, with facilities in every city nationwide that are equipped to perform such tests. Typically, 1.5 to 2 inches of hair from the crown or body suffices. Hair samples can be analyzed for drugs, alcohol, ETG, or other tailored testing needs.
Over recent years, drug testing methods have increasingly aligned towards the use of hair follicle tests. This shift sees many employers, judicial systems, and substance abuse experts opting for hair drug tests rather than the more conventional urine tests. Zero-tolerance firms, courts, and probation officers adopt these tests for their extended detection capabilities, which span up to 90 days, featuring an observed collection process that is tough to manipulate. Yet, to detect very recent drug use within 5 days, urine tests remain the most precise.

Hair testing is recognized as an effective method for identifying drug and alcohol use. Hair offers an extended timeline of substance usage by embedding biomarkers in the strands of growing hair. When hair is taken near the scalp, it can reveal up to around a 3-month period of drug and alcohol presence. The hair collection process is straightforward, making it less susceptible to tampering and easy to transport.
A sample measuring 1.5 inches from about 200 strands of hair (about as thick as a #2 pencil) next to the scalp yields 100mg, which is the recommended quantity for screening and verification. For EtG, additions, and/or tests exceeding 10 panels, 150mg is suggested. Utilizing a jeweler's scale for specimen measurement is advised. If scalp hair isn't present, an equivalent body hair sample should be taken. The term head hair exclusively denotes scalp hair, while body hair encompasses all other variations (facial, axillary, etc.).
Process Overview
The core stages in processing drug test results in a laboratory are Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the preliminary registration of a sample within a lab's framework. It confirms secure shipping and sealing of the sample, allots a random LAN (Laboratory Accessioning Number), and handles any supplementary data input absent in an electronic custody documentation system.
Screening provides an expedient assessment for drugs. Despite Screening being a cost-efficient approach to detect drug usage in most samples, a positive outcome necessitates substantiation for judicial acceptability. Any samples indicating a presumptive positive in Screening need follow-up confirmation.
Presumptive positive samples from the Screening phase then have additional hair taken from the initial sample for Extraction. At this stage, drugs are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which indicates why hair-based drug testing is particularly challenging.
Positive screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are washed before confirmation as necessary. The complete laboratory process from Accessioning to Confirmation is assessed in accordance with both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 criteria.

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.
