Accredited Drug Testing offers comprehensive hair follicle drug evaluations in Groves, Texas. If you're in need of a hair-based drug or alcohol screening, our focus on hair tests is unmatched, with centers ready in all major cities across the country to conduct such assessments. Typically, a hair length of 1.5 to 2 inches from the scalp or other body parts is required. These tests can detect drug usage, alcohol/ETG, or other tailored hair testing requirements.
Recently, there's been a growing trend towards utilizing hair follicle drug screenings over others. This method is now chosen more often by employers, legal entities, and Substance Abuse specialists over traditional urine testing. Hair follicle tests serve well for organizations with strict anti-drug policies, judicial systems, and individuals on probation. A distinct advantage of these tests is their 90-day detection window, performed via an oversight process difficult to falsify. Conversely, urine tests are favored for drug detection within a narrow five-day window.

The perception of hair testing has shifted to recognize it as an effective mechanism for identifying drug and alcohol usage. Hair stores a comprehensive record of alcohol and drug consumption by embedding biomarkers within the strands of its growth. When procured near the scalp, hair can reveal a detection scope of roughly three months for substances. The procedure of collecting hair is straightforward, moderately resistant to tampering, and easy to transport.
An ideal sample size of 1.5 inches, consisting of around 200 hair strands (similar to the bulk of a #2 pencil) near the scalp, yields 100mg of hair suitable for both screening and confirmation. For EtG tests, supplementary analyses, and evaluations exceeding 10 panels, a 150mg sample is advised. Utilizing a jeweler’s scale for measuring the specimen is suggested. In cases where scalp hair is not obtainable, a comparable amount of body hair may be gathered. References to head hair pertain exclusively to scalp hair. In contrast, body hair encompasses all alternative types (facial, axillary, etc.).
Process Overview
The drug test laboratory process includes four essential steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the preliminary introduction of a sample to the lab’s framework. This step confirms the sample was securely sealed and shipped, allocates a randomly generated LAN (Laboratory Accessioning Number), and addresses any pending data entry not covered by an electronic chain of custody system.
Screening is executed as a swift initial evaluation for substance abuse. Although Screening effectively rules out drug use in most samples at a lesser cost, results must be validated if they are to be used legally. Any samples indicative of drug use in Screening demand further confirmation.
For samples indicating drug use during Screening, more hair is separated from the initial batch for Extraction. During Extraction, substances are derived from hair at a significantly lower concentration relative to other methods (e.g., urine or oral fluid), rendering hair drug screening an intricate process.
GC/MS, GC/MS/MS, or LC/MS/MS processes affirm any positive Screening outcomes. When necessary, all presumptive positive samples undergo cleansing prior to Confirmation. Each step from Accessioning to Confirmation is assessed by the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Although referred to as "hair follicle tests," the analysis focuses on the hair strand instead of the follicle below the scalp.

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.
