Accredited Drug Testing provides comprehensive hair follicle drug testing services in Bellevue, Texas. For those requiring a drug or alcohol hair test, our specialization in hair analysis is supported by testing locations across the nation, including cities everywhere. Generally, a hair sample of 1.5 to 2 inches from the crown or body is suitable for testing. Hair analysis can be conducted for drugs, alcohol/ETG, and other tailored testing services.
Lately, hair follicle testing has gained prominence as a standard drug testing method. It is preferred by many employers, judiciary, and substance abuse experts over conventional urine tests. Organizations with stringent drug-free policies, courts, and probationary measures increasingly utilize hair drug tests. The major advantage lies in its extended detection window of up to 90 days, collected under supervision which is almost impossible to fake. However, for recent drug consumption within 5 days, urine tests remain more reliable.

Hair analysis has emerged as an effective means for detecting drug and alcohol consumption. Hair offers an extended record of substance use by capturing biomarkers within the developing hair strand. When gathered near the scalp, hair can offer nearly a 3-month detection period for both alcohol and other substances. Its collection is straightforward, it's relatively resistant to tampering, and it's convenient to transport.
A 1.5-inch segment consisting of roughly 200 hairs (about the thickness of a #2 pencil) from the scalp provides 100mg of hair, which serves as the optimal sample for testing and verification. For EtG supplements and/or tests exceeding 10 panels, a specimen of 150mg is advised. We suggest using a jeweler’s scale to weigh the sample. If scalp hair isn't accessible, an equivalent portion of body hair can be used. By "head hair," we specifically mean scalp hair, while "body hair" includes all other types (facial, axillary, etc.).
Process Overview
The four primary stages in the laboratory analysis of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into a lab’s framework. This involves confirming the sample's secure sealing and shipment, allocating a random LAN (Laboratory Accessioning Number), and completing any supplemental data recording if not covered by an electronic chain of custody system.
Screening entails a preliminary rapid examination for substance use. Although Screening is an economical method to dismiss drug consumption in most samples, a positive outcome necessitates confirmation for legal acceptability. Any samples preliminarily positive in Screening mandate subsequent validation.
Upon a presumptive positive result in the Screening phase, additional hair is derived from the original sample and readied for Extraction. Here, drugs are extracted from hair at significantly lower levels compared to other methods (e.g., urine or oral fluid), rendering hair drug testing one of the most challenging techniques.
Confirmation of any positive Screening finding is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All samples initially positive are cleansed before confirmation if required. The entire laboratory procedure from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair criteria and accreditation to ISO / IEC 17025 standards.

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.
