In Keenan, Texas, Accredited Drug Testing provides comprehensive hair follicle drug tests. Our expertise in hair testing means we have centers all across the nation ready to conduct these tests. Typically, you need 1.5 to 2 inches of hair from your head or body for testing. These tests screen for drugs, alcohol/ETG, or can be customized for other specific needs.
Increasingly, the use of hair follicle drug tests has been adopted over traditional urine tests. Employers, legal systems, and substance abuse counselors now prefer hair testing. This method benefits from a more extended detection period, lasting up to 90 days; the process is observed and is largely cheat-proof. However, urine tests remain the preferred choice for detecting recent drug use within the last five days.

Recognized as a robust method for identifying drug and alcohol consumption, hair analysis offers an extensive record by embedding biomarkers within the growing fibers. When samples are taken near the scalp, the test can reveal substance use spanning up to three months. The collection process for hair is straightforward, poses challenges to tampering, and allows for convenient transportation.
Gaining accurate results requires a 1.5-inch portion comprising about 200 hair strands (comparable to a #2 pencil thickness) collected nearest the scalp, ensuring about 100mg, which is optimal for analysis. For comprehensive checks, such as EtG additions or tests exceeding 10 panels, 150mg of hair is advised. The specimen’s weight should be verified using a jeweler’s scale. Should scalp hair be unavailable, equivalent body hair may be used. References to head hair specifically address scalp hair, while body hair encompasses all other types (e.g., facial, axillary).
Overview of the Process
The laboratory analysis of a drug test encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning denotes the initial integration of the sample into the lab’s system. This phase ensures that the sample is properly sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and completes any necessary information not entered electronically.
Screening provides a preliminary assessment for illicit substances. Despite its cost-efficiency in excluding drug use for most samples, positive screenings necessitate verification to be permissible legally. Samples returning presumptive positive results in Screening undergo additional confirmation.
In cases of presumptive positivity during Screening, additional hair from the original sample is prepared for Extraction. During Extraction, drugs are separated from the hair at concentrations significantly lower than alternative methods (e.g., urine or oral fluid), underscoring the complexity of hair drug testing.
Verification of any positive screening outcomes is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed prior to confirmation when necessary. The complete laboratory process, from Accessioning to Confirmation, aligns with both CAP (College of American Pathologists) Hair standards and ISO/IEC 17025 accreditation.
Merits of hair drug testing:
Drawbacks:
Important: Often called "hair follicle tests", the actual test involves analyzing the hair strands, not the follicles under 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. 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.
