Accredited Drug Testing provides comprehensive hair follicle drug tests in Spraberry, Texas. If a hair drug or alcohol test is needed, our nationwide testing centers, including those in every city, are at the ready. A hair length of 1.5 to 2 inches on the crown or body is generally necessary. These tests are versatile, detecting drugs, alcohol/ETG, or custom options.
Recently, hair follicle drug testing has become the preferred method over traditional urine tests. Many employers, judicial systems, and substance abuse experts now favor hair testing. Employers with zero-tolerance policies and courts often rely on this method. Key advantages include its extended detection window of up to 90 days and minimal chance of procedural tampering. However, for drug use within the last 5 days, urine tests remain more precise.

Hair analysis is increasingly considered an effective method for identifying drug and alcohol consumption. Hair strands offer a long-term record of alcohol and drug use by embedding substances in the hair as it grows. When harvested close to the head, hair can reveal drug or alcohol exposure for a span of about three months. Hair collection is straightforward, hard to tamper with, and convenient to transport.
A hair sample measuring 1.5 inches and consisting of roughly 200 hairs (similar in size to a #2 pencil) from near the scalp yields 100mg of hair, the optimal quantity for both initial testing and confirmation. For enhanced tests such as EtG or those exceeding 10 panels, a 150mg specimen is advisable. It is best to measure the sample weight using a jeweler’s scale. In cases where scalp hair is not present, an equal mass of body hair can be utilized. References to head hair pertain solely to scalp hair, while body hair encompasses all other types (facial, armpit, etc.).
Process Overview
The core stages in a lab's drug test processing include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step where a sample is integrated into a lab's system. This phase ensures the sample was correctly secured and transported, assigns a unique LAN (Laboratory Accessioning Number), and completes any other necessary data that is not included in an electronic chain of custody.
Screening offers a rapid evaluation for substances that might be abused. While it’s a cost-efficient method to detect drug use in most samples, any result from Screening indicating drug presence must be verified for legal acceptability. Samples showing presumptive positivity in Screening necessitate a follow-up confirmation.
If Screening suggests a sample is positive, additional hair is extracted from it for thorough Extraction. In this phase, concentrated drugs are separated from hair at notably reduced levels compared to techniques like urine or oral fluid tests, highlighting the complexity of hair-based testing.
Confirmation for any positive screen outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Before Confirmation, any presumptively positive samples are cleansed as required. This comprehensive testing process, spanning Accessioning to Confirmation, is evaluated against the standards set by both the CAP (College of American Pathologists) Hair designation and the accreditation criteria of ISO / IEC 17025.

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.
