Accredited Drug Testing provides comprehensive hair follicle drug testing services in Big Lake, Texas. Specializing in hair testing for drugs or alcohol, our centers across all U.S. cities can perform these tests. Generally, having 1.5 to 2 inches of hair on the crown or body suffices. Our hair tests check for drugs, alcohol/ETG, or other specific testing needs.
Recently, hair follicle drug tests have gained prominence for drug testing. Employers, courts, and substance abuse experts prefer hair tests over urine tests due to zero-tolerance policies and probation requirements. Hair tests offer a longer detection period of up to 90 days, are observed during collection, and are hard to cheat. However, urine tests remain the most accurate for recent drug use within the past 5 days.

Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair can reveal a long-term history of substance ingestion because the fibers store biomarkers as the hair grows. When hair is sampled near the scalp, it can offer an approximate 3-month detection period for alcohol and other substances. Hair collection is straightforward, challenging to tamper with, and easy to transport.
A 1.5-inch segment of roughly 200 hair strands (comparable in size to a #2 pencil) taken nearest to the scalp provides about 100mg, which is optimal for testing. For EtG, add-ons, and/or assessments over 10 panels, 150mg is advisable. It's best to weigh the hair using a jeweler's scale. If scalp hair isn't available, a similar amount of body hair can be used. When mentioning head hair, we mean only scalp hair. Body hair refers to all other types (facial, axillary, etc.).
Process Overview
The drug testing process in a laboratory encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is about the initial entry of a sample into a lab’s database. This step ensures the sample was properly sealed and dispatched, a random LAN (Laboratory Accessioning Number) is assigned, and any extra data entry not handled by an electronic custody framework is completed.
Screening is an initial assessment for substance abuse. Although Screening is an economical method for excluding drug use in the bulk of samples, any screen indicating presence must be verified to stand in legal contexts. Samples that show presumptive positives in Screening need further confirmation.
Should a sample reveal presumptive positives in Screening, excess hair is extracted from the original specimen and prepared for Extraction. At this stage, drugs are removed from hair at considerably lower concentrations compared to other methods (such as urine or saliva), highlighting the challenge of hair drug screenings.
Confirmation of any hypotheses positives is performed via GC/MS, GC/MS/MS or LC/MS/MS techniques. Each presumptive positive sample is cleansed before confirmation when necessary. The complete lab process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair standard and the accreditation of ISO/IEC 17025.

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.
