In McEwen, Tennessee, Accredited Drug Testing provides comprehensive hair follicle drug testing services. Specializing in both hair drug and alcohol tests, our extensive network boasts centers throughout all Nationwide cities. Generally, a hair length of 1.5 to 2 inches on the head or body is required. Hair analysis can include drugs, alcohol/ETG, or other customized testing options.
Recently, the trend in drug testing increasingly favors hair follicle testing. Employers, courts, and substance abuse professionals are opting for hair tests over traditional urine tests. Hair tests serve zero-tolerance organizations, courts, and probation requirements. Their key advantage is a longer detection period—up to 90 days—through observations that minimize cheating risks. Nevertheless, for detecting drug use within the last 5 days, urine tests remain more precise.

Hair testing has emerged as a significant method for monitoring drug and alcohol consumption. Hair captures long-term data regarding substance use by embedding biomarkers within the strands as they develop. When clipped near the scalp, hair offers a detection period of up to roughly three months for alcohol and drugs. The collection process is straightforward, challenging to tamper with, and convenient to transport.
A hair sample of 1.5 inches, consisting of approximately 200 strands (similar in size to a #2 pencil), and nearest to the scalp yields 100mg of hair, which is ideal for analysis and verification. For tests including EtG, add-ons, and those exceeding 10 panels, 150mg of the sample is advised. We suggest using a jeweler's scale for weighing the sample. If head hair is not accessible, an equal quantity of body hair can be utilized. The term 'head hair' specifically refers to hair from the scalp, while 'body hair' includes all other types (such as facial, axillary, etc.).
Process Overview
The process of determining a drug test result in a laboratory includes Accessioning, Screening, Extraction, and Confirmation.
Accessioning means entering a sample into the laboratory's system. This stage checks that the sample has been sealed and transported correctly, assigns it a random LAN (Laboratory Accessioning Number), and inputs any missing data that wasn't included in an electronic chain of custody.
Screening involves a preliminary scan for substances that are commonly abused. While Screening is an efficient means to eliminate the possibility of drug usage in most samples, a positive result requires confirmation before it holds up legally. Samples found to be presumptively positive during Screening necessitate an additional confirmation.
Should a sample test presumptively positive during Screening, additional hair is extracted from the original sample for analysis during the Extraction phase. Here, drugs are removed from the hair at much lower concentrations compared to other testing methods (e.g., urine or oral fluids), making hair drug testing the most challenging method to execute.
Any positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results undergo washing before confirmation if necessary. The entire laboratory procedure from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: While often known as "hair follicle tests," the analysis focuses on the hair strand, not the hair 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.
