Accredited Drug Testing provides comprehensive hair follicle assessments in Locust Grove, Oklahoma. If you require a drug or alcohol hair test, Accredited Drug Testing is a hair test specialist with facilities in cities across the nation that can carry out hair examinations. Typically, 1.5 to 2 inches of hair from your scalp or body are needed. Analysts can test hair samples for drugs, alcohol/ETG, or offer additional testing options.
Hair follicle drug tests have increasingly become the preferred method in recent years. Numerous employers, legal systems, and Substance Abuse professionals now favor hair tests over traditional urine analyses. Employers adhering to zero-tolerance policies, courts, and probation departments all use these tests. The primary advantage of hair follicle testing is its extended detection period, often up to 90 days, which uses an observed collection process and is nearly impossible to falsify. Nevertheless, for recent drug use (within the past 5 days), urine tests remain more accurate.

Hair analysis has emerged as an effective means for detecting drug and alcohol consumption. Hair offers an extensive timeline of alcohol and drug presence by embedding biomarkers within its growing strands. When harvested near the scalp, hair can reveal substance use over approximately a 3-month span. It is easy to gather, hard to tamper with, and straightforward to transport.
A specimen of 1.5 inches, roughly 200 hair strands (comparable in size to a #2 pencil) near the scalp, yields 100mg of hair, the optimal quantity for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advisable. We advocate measuring the sample on a jeweler’s scale. If scalp hair isn't available, an equivalent quantity of body hair can be used. Scalp hair specifically means head hair, while body hair includes all other types (facial, axillary, etc.).
Process Overview
Lab processing of a drug test outcome encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial sample induction into the lab's framework. This step certifies proper sealing and shipment of the sample, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any additional data entry not given by an electronic custody chain system.
Screening performs a preliminary drug check. While Screening economically precludes drug use in most cases, a positive result requires verification for legal acceptability. Any sample yielding a presumptive positive in Screening mandates a follow-up confirmation.
When a sample shows presumptive positivity during Screening, additional hair is collected from the original specimen for Extraction. In this phase, drugs are extracted at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), highlighting why hair drug testing is the toughest screening method to master.
Confirmation of positive screenings is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before confirmation, presumptive positive samples undergo washing as required. The entire lab sequence, from Accessioning to Confirmation, is conducted under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 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.
