In Palmer, Tennessee, Accredited Drug Testing provides comprehensive hair follicle drug testing services. Our centers, located in cities nationwide, offer specialized hair and alcohol tests. Typically, a hair length of 1.5 to 2 inches is required, either from the scalp or body. These tests can identify drugs, alcohol/ETG, and offer tailored testing solutions.
Hair follicle drug tests are increasingly favored over urine tests for drug screening. Employers, courts, and substance abuse professionals often prefer hair tests due to their zero-tolerance policies. Hair tests capture drug use over 90 days, conducted under observation with minimal chance of tampering. However, for detecting recent drug use within 5 days, urine tests remain most precise.

Hair analysis is increasingly recognized for its effectiveness in detecting drug and alcohol consumption. It captures a history of substance use over an extended period by embedding biomarkers within the fibrous structure of the hair as it grows. When hair is sampled near the scalp, it can detect alcohol and drugs over approximately a three-month timespan. Hair collection is straightforward, tampering is challenging, and it is easily transportable.
A section of hair measuring 1.5 inches, comprising roughly 200 strands similar in size to a #2 pencil and taken nearest the scalp, provides 100mg—ideal for screening and confirmation purposes. For EtG testing, additional panels, or tests exceeding ten panels, the suggested amount is 150mg. It is advised to weigh the sample using a jeweler's scale. In cases where scalp hair isn’t available, an equivalent amount of body hair can be utilized. "Head hair" specifically refers to the scalp, while "body hair" encompasses all other types like facial or axillary hair.
Process Overview
The laboratory procedure for processing drug test results involves four core stages—Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the initial step where a sample is integrated into the laboratory system. It involves ensuring the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and filling in any additional data not captured through an electronic chain of custody system.
Screening acts as an initial, prompt assessment for substances commonly abused. While it is an economical method to dismiss drug usage in most samples, a positive result requires confirmation for legal validation. Samples that yield a presumptive positive result during Screening must undergo further confirmation.
For samples deemed presumptively positive during Screening, additional hair is retrieved from the initial sample for the Extraction phase. This process involves extracting drugs from the hair at significantly lower concentrations than methods like urine or oral fluids, underscoring the complexity and precision of hair drug testing.
Confirmatory analysis of positive screening outcomes employs GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo a wash step before confirmation as needed. The entire sequence from Accessioning to Confirmation is subject to review under both the CAP (College of American Pathologists) Hair Program and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Often called "hair follicle tests", these tests actually assess the hair strand, rather than 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.
