Accredited Drug Testing offers comprehensive hair follicle drug testing in Chapel Hill, Kentucky. If a hair drug or alcohol test is needed, we specialize in hair testing and have nationwide testing centers that can conduct these tests. Typically, 1.5 to 2 inches of hair is required from the crown of the head or body. Hair tests can determine drugs, alcohol/ETG, or other customized testing options.
In recent times, hair follicle drug testing has been increasingly favored for drug screenings. This method is required by several employers, courts, and Substance Abuse professionals over urine tests. Hair tests are valuable for employers with strict no-drug-use policies, courts, and probation programs. The key advantage is its long detection window, up to 90 days, with an observed collection making it difficult to tamper with. However, for recent drug use within 5 days, urine tests remain more accurate.

Hair testing has emerged as an effective tool for identifying drug and alcohol consumption. Hair captures a long-term history of substances by embedding biomarkers within the fibers of the continuously growing hair strand. When acquired close to the scalp, hair allows for approximately a 3-month detection period for alcohol and other substances. The collection of hair is straightforward, moderately tough to tamper with, and straightforward to transport.
A 1.5-inch section comprising about 200 strands of hair (approximately the width of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the perfect sample for initial analysis and confirmation. For EtG, additional tests, or tests beyond 10 panels, 150mg of the sample is advised. It is recommended to weigh the specimen using a jeweler’s scale. If scalp hair is not an option, a similar amount of body hair may be taken. In terms of head hair, we specifically mean scalp hair only. Body hair denotes all other hair types (facial, axillary, etc.).
Process Overview
The four fundamental stages involved in the laboratory analysis of a drug test are Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary handling of a sample in a laboratory’s system. This step involves verifying that the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and finalizing any additional data entry absent from an electronic chain of custody system.
Screening entails a rapid initial assessment for substances of abuse. While Screening is a cost-efficient method to eliminate drug use across the majority of samples, a positive screen requires confirmation to be admissible in legal settings. Any samples that return a preliminary positive during Screening necessitate a follow-up confirmation.
If a sample shows presumptive positivity during the Screening process, further hair is extracted from the initial collection and prepped for Extraction. At this stage, substances are removed from the hair at significantly lower concentrations than other techniques (e.g., urine or oral fluid), making hair drug testing the most challenging methodology to execute.
Confirmation of any positive screening results is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation when required. The complete laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although often referred to as "hair follicle tests", this test analyzes 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.
