In Petersburg, Tennessee, Accredited Drug Testing excels in comprehensive hair follicle drug screening. Whether you're seeking a hair drug or alcohol test, our expertise in hair analysis stands out, with facilities distributed across all cities Nationwide. Typically, 1.5 to 2 inches of head or body hair is needed. A variety of substances, including drugs and alcohol/ETG, can be assessed through these tests.
Over recent years, drug testing procedures have increasingly incorporated hair follicle methods. Employers, courts, and substance abuse counselors often prefer hair drug tests over traditional urine tests. Hair follicle analysis suits organizations enforcing strict no-drug policies, judicial systems, and probationed individuals. Its key advantage is a longer detection window, reaching up to 90 days, nearly tamper-proof. However, urine tests remain optimal for detecting drugs used within the recent 5-day timeframe.

Hair testing is regarded as an effective means for identifying drug and alcohol consumption. The hair retains markers from these substances within its strands, offering a comprehensive timeline. When sampled proximate to the scalp, hair enables detection of substances up to nearly 90 days. Collection of hair is straightforward, relatively tamper-resistant, and easy for shipping purposes.
A 1.5-inch sample consisting of 200 hair strands (around the thickness of a #2 pencil) nearest to the scalp achieves 100mg, which is the optimal sample size for analysis. In cases of EtG tests, extended panels, or tests exceeding 10 panels, a specimen amount of 150mg is advised. Measurement should be conducted using a jeweler’s scale. If scalp hair is not available, a comparable quantity of body hair can be used. When mentioning head hair, we mean scalp hair exclusively. Body hair pertains to other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of drug test samples consists of four pivotal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails entering a sample into the lab's system. It involves ensuring the sample's packaging and transport were done securely, assigning a randomized LAN (Laboratory Accessioning Number), and filling in any missing data that is not included in an electronic chain of custody.
Screening involves conducting a preliminary evaluation for substance abuse. Although a cost-efficient method to exclude many samples from drug use, any positive result from the Screening phase must be confirmed for judicial acceptance. Samples tentatively positive during Screening necessitate additional Confirmation.
When a sample might test positive in the Screening phase, more hair is selected from the original batch for Extraction. In this step, substances are isolated from hair in concentrations significantly lesser than other testing types (e.g., urine or saliva). This unique aspect makes hair testing notably challenging.
Positive results from the Screening phase are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS processes. All presumptive positives are cleaned prior to Confirmation as needed. The complete process from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) Hair specifications and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Frequently called “hair follicle testsâ€, the analysis targets the hair strand instead of the follicle beneath the scalp.

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. As we embrace these advancements, we pave the way for a safer, healthier society, where drug testing and analysis serve as powerful tools in protecting public health and maintaining integrity in various sectors. The research presented in this special issue will undoubtedly shape the future of drug testing and analysis, fostering collaboration and inspiring further innovation in this crucial area of scientific inquiry.
