Accredited Drug Testing offers comprehensive hair follicle drug screening in Olivarez, Texas. Whether requiring a drug or alcohol analysis through hair sampling, our specialty in hair testing is supported by centers located in cities nationwide. Typically, 1.5 to 2 inches of hair from the scalp is needed, though body hair may suffice. Hair tests assess the presence of drugs, EtG, and more, tailored to specific testing needs.
Over recent years, drug testing has increasingly adopted the hair follicle method. Companies, judicial systems, and Substance Abuse experts are favoring hair drug tests over traditional urine analysis. Employers upholding zero-tolerance on substance use, court decisions, and probation conditions often employ hair testing. This method's advantage lies in its extended detection window, often reaching up to 90 days, collected under supervision, making it highly difficult to tamper with. However, for detecting use within 5 days, urine analysis remains unmatched.

Hair analysis has gained recognition as an effective method for identifying drug and alcohol consumption. The hair captures biomarkers within the strands as it grows, providing a comprehensive history of alcohol and drug use. When gathered near the scalp, hair can reveal substance use for up to three months. It's easy to collect, challenging to tamper with, and straightforward to transport.
Collecting a 1.5-inch section of approximately 200 hair strands (similar in size to a #2 pencil) closest to the scalp yields 100mg, ideal for assessment and verification. For tests with EtG, add-ons, or more than 10 panels, a sample of 150mg is advised. We suggest using a jeweler’s scale for accuracy. If scalp hair isn't accessible, an equivalent amount of body hair can suffice. "Head hair" specifically refers to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The key stages in laboratory drug test processing include Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial integration of a sample into the laboratory. This process ensures the sample was securely sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data needed that isn't covered by an electronic chain of custody system.
Screening is a preliminary check for drug presence. While cost-efficient for most samples, any positive screen results require confirmation for legal validation. Samples with a presumptive positive from Screening need further analysis.
If a sample shows presumptive positivity in Screening, additional hair is extracted from the initial sample for the Extraction phase. Here, drugs are extracted from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), making this the most complex drug testing method.
Positive results from Screening undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples are cleaned before confirmation if necessary. The complete process from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although commonly termed "hair follicle tests", the analysis targets the hair strand, not the follicle beneath the scalp.

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.
