Accredited Drug Testing provides comprehensive hair follicle drug testing services in Abbott, Texas. When you require a hair-based drug or alcohol screening, our expertise in hair testing is unmatched, with testing facilities available in all cities Nationwide. Typically, a minimum of 1.5 to 2 inches of hair from your scalp or body is necessary. Our hair tests can detect drugs, alcohol/ETG, or cater to other custom testing needs.
In recent years, the trend in drug testing has increasingly leaned towards hair follicle methodologies. A growing number of employers, judicial systems, and substance abuse specialists are favoring this method over conventional urine tests. Hair follicle tests are employed by firms with strict drug-free policies, legal entities, and for individuals on probation. The chief advantage of hair testing lies in its ability to detect drug use over an extended period of up to 90 days, ensuring sample integrity through an observed collection, and making it extremely difficult to tamper with. Nonetheless, urine tests remain the most precise for detecting recent drug use within the last five days.

Hair testing has emerged as a formidable method for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug use by embedding biomarkers within the growing strand. When cut near the scalp, hair offers roughly a 3-month period for detecting alcohol and other drugs. It's straightforward to collect, relatively tamper-resistant, and simple to transport.
A 1.5-inch lock of about 200 hair strands (about the diameter of a #2 pencil) nearest the scalp will produce 100mg of hair, which is the optimal sample size for assessment and verification. For EtG, additional tests, and panels exceeding 10, a 150mg sample is advisable. Utilizing a jeweler’s scale for measurement is recommended. If scalp hair can't be collected, a similar quantity of body hair is acceptable. By head hair, we specifically mean scalp hair. Body hair pertains to all other types (facial, axillary, etc.).
Process Overview
The laboratory process of drug testing comprises four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial entry of a sample into the lab’s system. This step ensures the sample was sealed and delivered correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any data entry missing from an electronic chain of custody system.
Screening conducts a preliminary swift check for drug abuse. Though Screening is cost-efficient for ruling out drug use in most samples, court admissibility requires confirmation of a positive screen. Samples testing positive at Screening require further confirmation.
Should a sample be positive at the Screening phase, more hair is taken from the initial specimen for Extraction. In this stage, drugs are isolated from hair at significantly lower concentrations than with other methods (e.g., urine or oral fluid), which makes hair drug screening the most challenging method to conduct.
Confirmation of any positive screen result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples are washed before confirmation as necessary. The lab process from Accessioning to Confirmation complies with both CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.

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.
