Accredited Drug Testing offers comprehensive hair follicle drug tests in Grays Prairie, Texas. When in need of a hair or alcohol test, Accredited Drug Testing excels in hair testing, with centers in cities nationwide ready to perform the test. Typically, 1.5 to 2 inches of hair from the crown or body suffices. Hair tests can be tailored for drugs, alcohol/ETG, or other specific hair testing needs.
In the past few years, the choice for administering drug tests has increasingly favored hair follicle tests. Employers, courts, and Substance Abuse experts often require hair drug tests instead of standard urine tests. Hair tests are preferred by employers with zero-tolerance policies, judicial systems, and probationers. The main advantage is its longer detection window, usually up to 90 days, collected under observation, minimizing cheating. Nevertheless, urine tests remain most effective for detecting recent drug use—within the past 5 days.

Hair testing is increasingly recognized as an effective means of identifying the use of drugs and alcohol. Hair captures a prolonged alcohol and drug history by securing biomarkers within its growing strands. When sampled near the scalp, it can offer roughly a 3-month detection timeframe for both alcohol and drugs. Hair collection is straightforward, less prone to tampering, and is convenient to transport.
Obtaining a 1.5-inch portion of roughly 200 hairs (similar in thickness to a #2 pencil) near the scalp provides 100mg, which is the perfect amount for screening and confirmation purposes. For EtG, additional tests, or panels exceeding 10, a 150mg sample is advisable. It's suggested to weigh the sample with a jeweler’s scale. If head hair is not obtainable, an equivalent quantity of body hair may be gathered. When mentioning head hair, it signifies only scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
There are four key procedures in the laboratory evaluation of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step where a sample is integrated into a laboratory’s system. This step involves confirming the sample’s seal and proper shipment, giving it a LAN (Laboratory Accessioning Number), and completing any data entry not handled by an electronic chain of custody system.
In the Screening phase, a quick primary assessment for drugs of abuse is conducted. Though Screening provides a cost-efficient method to dismiss drug usage in most cases, any positive screen must be verified for legal admissibility. Samples yielding preliminary positive results in Screening must undergo secondary confirmation.
When a sample shows a presumptive positive result at Screening, additional hair is taken from the original sample for Extraction. Here, drugs are removed from hair at concentrations much lower than those used in other methods (e.g., urine or oral fluid), making hair drug testing the most challenging method to execute.
Confirming any positive screening involves techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are washed before confirmation as required. The process from Accessioning through Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards 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.
