Accredited Drug Testing offers comprehensive hair follicle testing in Covington, Tennessee. When in need of a drug or alcohol hair test, Accredited Drug Testing is an expert in this area with numerous centers across the nation, including hair testing facilities in every major city. Typically, 1.5 to 2 inches of hair from one's head or body is required for the test, and we provide analysis for drugs, alcohol/ETG, or personalized hair testing options.
Lately, hair follicle drug testing has been increasingly incorporated into drug testing methods. Many employers, legal systems, and substance abuse authorities mandate hair drug tests over traditional urine exams. These tests are preferred due to their longer drug detection period of up to 90 days, are conducted under supervision, and are almost impossible to tamper with. Despite their advantages, urine tests remain the most effective for detecting recent drug use within the past five days.

Hair testing is regarded as an effective means to identify drug and alcohol consumption. Hair offers a long-term record of alcohol and other substances by capturing biomarkers within the strands of hair as they grow. By collecting hair near the scalp, it’s possible to obtain a detection timeline of up to roughly 3 months for various substances. Hair is straightforward to collect, notably challenging to tamper with, and convenient to transport.
A 1.5-inch segment comprising around 200 hair strands (about the width of a #2 pencil) nearest the scalp yields 100mg of hair, which is the optimal sample for analysis and confirmation. For EtG, additional tests, and/or panels exceeding 10, 150mg of hair is advisable. We suggest measuring the sample on a jeweler’s scale. If scalp hair is unavailable, a comparable quantity of body hair can be gathered. When mentioning head hair, we specifically refer to scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result entails four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a specimen into a lab's workflow. This step includes ensuring the sample was properly sealed and dispatched, issuing a random LAN (Laboratory Accessioning Number), and completing any remaining data input not covered by an electronic chain of custody system.
Screening provides an initial and rapid assessment for drug abuse. While it serves as an economical method to dismiss drug usage in the bulk of samples, a positive screening outcome must be ratified for legal acceptability. Samples that are presumptively positive during Screening demand additional confirmation.
If a sample shows a presumptive positive during Screening, additional hair is collected for Extraction. This phase involves separating drugs from hair with reduced concentrations compared to other techniques (ex. urine or saliva), which makes hair drug testing one of the most intricate methods to execute.
Confirmation of any positive screening outcomes is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing prior to confirmation as required. The complete lab process, from Accessioning to Confirmation, is examined under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Despite often being termed "hair follicle tests," the analysis focuses on the hair strand, not 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.
