Accredited Drug Testing offers comprehensive hair follicle drug testing in Comal, Texas. For hair drug or alcohol testing needs, Accredited Drug Testing is proficient in hair testing, with facilities available in all cities across the Nation to conduct hair tests. Typically, you need 1.5 to 2 inches of hair on your head or body for effective testing. Hair tests can screen for drugs, alcohol/ETG, or other tailored hair testing options.
Recently, hair follicle drug tests have become a preferred method for drug testing. Various employers, courts, and Substance Abuse professionals favor a hair drug test over a conventional urine test. These tests appeal to employers with strict drug policies, the judiciary, and those on probation. The main advantage is the extensive detection window, which reaches up to 90 days, collected in a verified manner, and is nearly tamper-proof. However, for detecting recent drug use within 5 days, urine tests remain the most precise.

Analyzing hair is increasingly recognized as an effective approach for identifying substance and alcohol consumption. Hair captures a prolonged record of alcohol and drug intake by enclosing biomarkers within the fibers of the growing strand. When obtained near the scalp, hair can reveal alcohol and drug presence for up to around three months. Collecting hair is straightforward, not easily tampered with, and conveniently shipped.
A sample measuring 1.5 inches comprising about 200 hair strands (approximately equivalent to a #2 pencil) closest to the scalp yields 100mg of hair, an ideal quantity for both screening and confirmation. For EtG, additional testing, or beyond 10-panel assessments, 150mg of the hair sample is suggested. It's advisable to measure the sample on a jeweler’s scale. If scalp hair isn't available, a similar quantity of body hair can be used. 'Head hair' specifically means scalp hair. 'Body hair' encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial entry of a sample into a lab’s workflow. This stage includes checking that the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data input that an electronic chain of custody system didn’t provide.
Screening entails an initial, rapid assessment for drugs of abuse. Although Screening is a cost-efficient method to eliminate drug use in most samples, confirming a positive screen is necessary for court acceptability. Any samples indicating presumptive positives during Screening need a subsequent confirmation.
If a sample shows a presumptive positive at Screening, more hair is retrieved from the initial sample and readied for Extraction. This stage involves extracting drugs from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), which is why hair drug screening is the most intricate method to conduct.
Confirmation of any positive screening outcome is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positives undergo washing before confirmation if required. The complete lab process from Accessioning to Confirmation is audited under both CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Despite being called "hair follicle tests", the analysis is conducted on the hair strand itself, not the follicle beneath 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. 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.
