Accredited Drug Testing offers comprehensive hair follicle drug testing services in Dirgin, Texas. For those requiring a hair drug or alcohol test, we are specialists in hair testing, providing services across the nation, with locations in every city prepared to conduct a hair test. Typically, 1.5 to 2 inches of hair from the head or body will be used. Hair samples can be tested for drugs, alcohol/ETG, or other tailored testing solutions.
In recent times, hair follicle drug testing has increasingly been adopted as a method of drug testing. Numerous employers, judiciary bodies, and Substance Abuse Counselors prefer hair tests over standard urine analysis. Hair follicle tests are favored in zero-tolerance environments, courts, and for individuals on probation. A key advantage is its ability to detect drug use over an extended period, usually up to 90 days, obtained through an observed collection process, making it difficult to tamper with. Nonetheless, for detecting recent drug use, within five days, the urine test remains the most reliable choice.

Hair analysis has emerged as a robust instrument for identifying drug and alcohol consumption. Hair can record a long-term timeline of alcohol and drugs by embedding biomarkers within the hair shaft. When gathered near the scalp, hair can reveal a detection period extending up to roughly three months for alcohol and drugs. Hair is straightforward to collect, somewhat difficult to tamper with, and convenient to transport.
A 1.5-inch segment of approximately 200 hair strands (about the width of a #2 pencil) nearest the scalp will provide 100mg of hair, which is the optimal quantity for analysis and verification. For EtG, additional testing, and/or panels exceeding 10, 150mg of hair is advised. It's best to use a jeweler’s scale for weighing the hair. If scalp hair is lacking, a comparable amount of body hair may be used. When mentioning head hair, we mean only scalp hair. Body hair includes all other hair types (facial, underarm, etc.).
Process Overview
The four essential steps in the analysis process of a drug test sample are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial integration of a sample into a test lab's framework. This comprises verifying the sample's seal and shipment integrity, allocating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not covered by an electronic chain of custody system.
Screening consists of a preliminary rapid inspection for abuse substances. Screening is an economical approach to exclude drug use in most samples, although a positive screen requires confirmation to be legally acceptable. Any samples that are tentatively positive in Screening necessitate a secondary confirmation.
If a sample shows a tentative positive in Screening, more hair is extracted from the original sample and processed for Extraction. During this step, drugs are isolated from hair at a much reduced concentration compared to other methods (like urine or saliva), making hair drug analysis the most challenging method to execute.
Verification of any positive Screening result is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All tentative positive samples are cleansed before confirmation if needed. The complete lab process from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair category and the accreditation to ISO / IEC 17025 benchmarks.

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.
