In Columbus, Texas, Accredited Drug Testing offers all-inclusive hair follicle testing services. Our centers across all major cities nationwide can conduct hair and alcohol tests. Typically, you need 1.5 to 2 inches of hair from the head or body for the analysis, which can detect drugs, alcohol/ETG, or be tailored for specific testing needs.
Recently, hair follicle testing has gained prominence in drug screening processes over traditional urine tests. This method is increasingly mandated by employers, courts, and Substance Abuse professionals due to their efficient zero-tolerance policy enforcement. Hair testing stands out due to its extended 90-day detection window, rigorous observation during collection, and resistance to manipulation, though urine tests remain more precise for usage detection within the past 5 days.

Hair analysis is now recognized as a potent method for identifying drug and alcohol consumption. Hair retains a prolonged record of substance use by encapsulating biomarkers within the hair fiber. When cut close to the scalp, hair can reveal substance use insights for up to an estimated 90-day period. Collecting hair is straightforward, relatively resistant to tampering, and easy to transport.
A sample measuring 1.5 inches from about 200 hairs (similar in size to a #2 pencil) nearest to the scalp yields 100mg—the optimal amount for initial testing and confirmation. For EtG, additional evaluations, and tests exceeding 10 panels, a specimen of 150mg is advised. It's best to weigh the sample with a jeweler’s scale. If scalp hair isn't available, a comparable volume of body hair might be gathered. When discussing head hair, we mean scalp hair exclusively. Body hair encompasses all other types (such as facial or axillary hair).
Process Overview
The laboratory process for a drug test result encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed into the laboratory’s system. This crucial phase involves confirming the sample's secure sealing and proper shipment, issuing a random LAN (Laboratory Accessioning Number), and entering any additional data not added by an electronic chain of custody.
Screening is a preliminary evaluation for drugs of abuse. As a budget-conscious method to identify non-use in the majority of samples, a positive screen still requires confirmation for court validity. Samples indicating a presumptive positive in Screening need further confirmation.
If the Screening stage suggests a presumptive positive result, additional hair is extracted from the provided sample for Extraction. In this phase, drugs are removed from hair at significantly reduced concentrations compared to methods like urine or oral fluid, highlighting the difficulty of performing hair drug screening.
Verification of any positive screening result is executed via techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Samples preliminarily positive are cleansed prior to confirmation as deemed necessary. The comprehensive lab process from Accessioning to Confirmation is assessed under CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standard accreditation.

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.
