Accredited Drug Testing offers thorough hair follicle drug evaluations in Lesley, Texas. Whether you require a hair drug or alcohol test, Accredited Drug Testing excels in this method, boasting centers nationwide capable of conducting such assessments. Typically, 1.5 to 2 inches of hair from the scalp or body can be utilized to detect drugs, alcohol/ETG, or other specific substances.
In recent years, hair follicle drug testing has become increasingly common. Employers, courts, and substance abuse professionals frequently prefer it over traditional urine testing. Hair follicle tests are ideal for employers with strict no-drug policies, judicial systems, and those on probation. These tests offer the advantage of detecting drug use over a prolonged period, generally up to 90 days, collected under observation and nearly uncompromisable. Yet, for recent drug use within five days, urine tests remain the most reliable option.

Hair analysis has gained recognition as a potent method for identifying substance and alcohol consumption. It tracks a prolonged timeline of drug and alcohol intake by embedding biomarkers within the growing hair shafts. If gathered close to the scalp, hair can reveal a detection period of up to three months for substances and alcohol. The collection process for hair is easy, hard to tamper with, and convenient for transport.
A segment of hair measuring 1.5 inches and containing about 200 strands (approximately the size of a #2 pencil) near the scalp will provide 100mg of hair, the preferred sample size for both preliminary and confirmatory testing. For EtG, additional analyses, and panels exceeding 10, 150mg is advisable. It is suggested to measure the sample on a jeweler’s scale. When scalp hair cannot be accessed, a comparable amount of body hair is an alternative. Head hair strictly refers to scalp hair, while body hair encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
The procedure for processing a drug test result in the lab comprises four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the primary handling of a sample within a laboratory framework. This phase involves confirming the correct sealing and shipping of the sample, generating a unique LAN (Laboratory Accessioning Number), and finalizing any additional data entry absent from an electronic chain of custody system.
Screening constitutes an initial swift evaluation for substance abuse. Although Screening offers a cost-efficient method to preclude drug usage in most cases, a positive result necessitates confirmation to be valid in legal settings. Presumptive positive samples in Screening require further validation.
Upon yielding a presumptive positive result in Screening, additional hair is extracted from the initial specimen for Extraction. This stage involves isolating drugs from hair at significantly lower concentrations than those found in other methodologies (e.g., urine or saliva), necessitating high precision in hair drug screening.
Confirmation of any positive screening finding is achieved using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Samples found to be presumptive positives undergo washing prior to confirmation if necessary. The complete laboratory operation from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation along with the ISO/IEC 17025 standards accreditation.
Advantages of hair drug testing:
Limitations:
Note: While commonly known as "hair follicle tests", the analysis is conducted on the hair shaft rather than the root 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.
