Accredited Drug Testing offers comprehensive hair follicle drug testing services in Nash, Texas. If you require a hair drug or alcohol test, we specialize in hair testing and have centers nationwide capable of conducting these tests. Generally, 1.5 to 2 inches of hair on the head or body is needed. Hair tests can detect drugs, alcohol/ETG, and offer customized testing options.
In recent years, drug testing methods have increasingly included hair follicle tests. Many employers, courts, and substance abuse professionals prefer hair tests over the traditional urine test. Hair follicle tests are ideal for employers with strict no-drug policies, courts, and individuals on probation. Their main advantage is an extended detection period, typically up to 90 days, with observable collection and minimal risk of trickery. However, for detecting recent drug use within the last 5 days, urine tests remain the most precise.

Hair testing is now regarded as a potent method for identifying drug and alcohol consumption. Hair retains a long-term record of substances by embedding biomarkers within the growing strands. When obtained near the scalp, hair offers an approximate 3-month detection period for these substances. It's easy to collect hair, fairly resistant to tampering, and straightforward to transport.
A 1.5-inch segment of roughly 200 hair strands, akin to the diameter of a #2 pencil, taken near the scalp, yields 100mg of hair, the optimal amount for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, 150mg of hair is preferred. We advise weighing the hair on a jeweler’s scale. Should scalp hair be absent, an equivalent quantity of body hair may be used. When mentioning head hair, we refer solely to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of drug test results involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial introduction of a sample into a lab's system. This step ensures the sample was correctly sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and completes any necessary data tasks not handled by an electronic chain of custody system.
Screening is a rapid preliminary test for drugs of abuse. While cost-effective for ruling out substance use in most samples, a positive screening result must be verified for legal acceptability. All samples testing positive in Screening require subsequent confirmation.
For samples with a positive result in the Screening phase, additional hair is extracted from the original sample for further processing in Extraction. Here, drugs are separated from hair at much lower concentrations than other tests (e.g., urine or oral fluid), emphasizing the complexity of hair-based drug testing.
To confirm any positive screening outcomes, methods such as GC/MS, GC/MS/MS, or LC/MS/MS are used. Before final confirmation, presumptive positive samples are washed as necessary. The entire laboratory workflow, from Accessioning to Confirmation, is conducted under the CAP (College of American Pathologists) Hair guidelines and in compliance with ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although sometimes called "hair follicle tests", the analysis focuses on 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. 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.
