In McDonald, Kansas, Accredited Drug Testing provides comprehensive hair follicle drug evaluations. Whenever a specific hair drug or alcohol analysis is needed, they excel in this testing format, offering facilities across all U.S. locations for convenience. A hair sample length of 1.5 to 2 inches from either the head or body is typically required for analysis. Various drug, alcohol/ETG, and personalized options are available through hair tests.
Lately, hair follicle drug testing has become increasingly common in drug detection. This method is favored by employers, judicial systems, and substance abuse experts over traditional urine tests. Employers with zero-tolerance drug policies, court systems, and probation officers frequently prefer hair drug testing due to its benefits. Key advantages include a detection window that spans up to 90 days, an observed sample collection process, and strong resistance to tampering. Urine tests, however, remain the most accurate for detecting recent drug use within 5 days.

Hair testing is increasingly recognized as an effective means for identifying drug and alcohol consumption. The fibers of a growing hair strand encapsulate biomarkers, providing a comprehensive long-term history of substance use. When obtained near the scalp, hair samples can reveal alcohol and drug usage over an approximate three-month period. Hair samples are straightforward to collect, have low susceptibility to tampering, and can be easily mailed.
A 1.5-inch sample comprising roughly 200 hair strands, about the diameter of a #2 pencil, close to the scalp yields roughly 100mg of hair—a perfect quantity for screening and verification. For EtG, add-ons, or tests exceeding 10 panels, a sample size of 150mg is advisable. We suggest weighing samples on a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair may be used. "Head hair" pertains exclusively to scalp hair, whereas "body hair" encompasses all other hair types, including facial and axillary hair.
Process Overview
The laboratory processing of a drug test result consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the initial phase, integrating a sample into a lab’s systems. This step includes ensuring the sample was properly sealed and conveyed, generating a unique LAN (Laboratory Accessioning Number), and completing additional data entries not captured by an electronic chain of custody.
Screening performs an initial preliminary check for the presence of drugs. Although cost-effective for eliminating drug use in most samples, a positive screen necessitates confirmation for legal acceptability. Any samples yielding presumptive positives in Screening require subsequent verification.
Should a sample show presumptive positivity during Screening, further hair is extracted from the initial material for Extraction. In this step, drugs are isolated from hair at much leaner concentrations relative to other methodologies (like urine or oral fluid), making hair drug screening the most complex methodology available.
To validate positive Screening outcomes, confirmation via GC/MS, GC/MS/MS, or LC/MS/MS is performed. All samples indicating presumptive positivity undergo washing prior to confirmation as dictated. The complete lab procedure, from Accessioning to Confirmation, undergoes scrutiny under the CAP (College of American Pathologists) Hair designation alongside conformity with ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although often labeled as "hair follicle tests", the analysis is conducted on the hair strand itself, not the subscalp follicle.

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.
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.
