In Laguna Seca, Texas, Accredited Drug Testing offers comprehensive hair follicle drug testing. If you're in need of hair drug or alcohol tests, our expertise in hair testing spans nationwide through our centers in every city, ready to conduct a hair analysis. Typically, a length of 1.5 to 2 inches of hair from the crown or body suffices. Hair testing can reveal the presence of drugs, alcohol/ETG, and offers custom options.
The prevalence of hair follicle drug tests in recent years has risen, with many employers, courts, and substance abuse professionals opting for this method over the traditional urine test. These tests are favored by employers with zero-tolerance policies, the judicial system, and probation officers. The key advantage of a hair follicle drug test is the extended detection window, often up to 90 days, obtained through an observed collection process, making it highly resistant to tampering. However, for substance use detection within the past 5 days, urine tests maintain superior accuracy.

Hair testing has emerged as a formidable method for detecting drug and alcohol consumption. Hair offers a prolonged historical record of alcohol and various drugs by embedding biomarkers within the fibers of the advancing hair strand. When obtained near the scalp, hair can present up to a roughly 3-month detection timeframe for alcohol and other drugs. Hair is straightforward to gather, relatively hard to tamper with, and simple to transport.
A 1.5-inch section of around 200 hair strands (approximately the girth of a #2 pencil) nearest to the scalp will provide 100mg of hair, the optimal amount for both screening and confirmation. For EtG, additional analysis, and/or tests exceeding 10 panels, 150mg of the sample is advised. It is recommended to measure the sample on a jeweler’s scale. If scalp hair is not accessible, an equivalent quantity of body hair can be collected. When discussing head hair, it pertains solely to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The four essential stages in the lab processing of a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a specimen into a laboratory’s system. This process includes validating that the specimen was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any supplemental data entry not supplied by an electronic chain of custody system.
Screening involves an initial rapid examination for drugs of abuse. While Screening is a cost-effective manner to eliminate drug use in most samples, a positive screen requires confirmation for admissibility in court. Samples that are presumptively positive during Screening necessitate a secondary confirmation.
If a sample tests presumptively positive during the Screening phase, additional hair is extracted from the initial sample and prepared for Extraction. In this stage, drugs are extracted from hair at a substantially lower concentration compared to other methodologies (e.g., urine or oral fluid), which is why hair drug screening is considered one of the most challenging methodologies to execute.
Confirmation of any positive screening outcome is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation as needed. The complete laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although commonly called "hair follicle tests", the test itself evaluates the hair strand and not the scalp-embedded follicle.

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.
