Specialized in hair follicle drug testing, Accredited Drug Testing offers thorough testing services in Channelview, Texas. Whether you require a hair analysis for drugs or alcohol, we are proficient in hair testing, with facilities available across all major cities nationwide. Typically, 1.5 to 2 inches of hair from the crown is required, though other areas can be used. Our tests examine substances like alcohol/ETG and offer tailored testing solutions.
Over the past years, hair follicle drug testing has become a more common method for substance detection. Employers, judicial systems, and substance professionals increasingly favor this test over standard urine tests. Hair tests benefit zero-tolerance policies by providing a longer detection window of up to 90 days, collected under supervision, making it difficult to tamper with. Still, for detecting recent drug use within 5 days, urine tests prove more accurate.

When you're searching for hair drug testing near me or hair drug testing locations, we provide a simple and convenient process to find a drug and alcohol testing location near you that is certified to provide all of your drug and alcohol testing needs.
Hair analysis is now recognized as an effective method for identifying drug and alcohol consumption. It offers a comprehensive record of substance use, capturing markers within the strands of hair as they grow. Hair samples taken close to the scalp can provide a look back period of up to three months for drug and alcohol usage. This method is easy to collect, hard to tamper with, and convenient for shipping.
A sample measuring approximately 1.5 inches and containing around 200 strands (similar in size to a #2 pencil) near the scalp can yield 100mg of hair, which is optimal for both screening and confirmation processes. For EtG testing, add-ons, or tests exceeding 10-panel, it’s advised to have 150mg of the specimen. Using a jeweler's scale is recommended to measure the sample. If scalp hair is not viable, a comparable amount of body hair can be provided. When referencing head hair, it pertains solely to scalp hair, while body hair encompasses all other types of hair (facial, axillary, etc.).
Process Overview
Four principal phases mark the laboratory evaluation of a drug test: Accessioning, Screening, Extraction, and Confirmation.
In the Accessioning phase, the sample is initially integrated into the lab’s system. The process includes ensuring the sample's integrity by verifying proper sealing and shipping, assigning an arbitrary LAN (Laboratory Accessioning Number), and recording any additional data absent from electronic custody systems.
Screening serves as a preliminary assessment to detect drug presence. Though this method efficiently eliminates drug use in most cases, a positive outcome necessitates further verification for legal acceptability. Samples showing potential positive results during Screening require subsequent Confirmation.
Should a sample indicate likely positive findings during Screening, additional strands are extracted from the initial sample for further preparation in the Extraction phase. Here, drugs are isolated from the hair at concentrations far lower than those in other testing methods (e.g., urine or oral fluids), underscoring the complexity of performing hair drug analysis.
Confirmation of positive screening results is executed using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples undergo necessary cleaning. The overarching laboratory procedure, spanning from Accessioning to Confirmation, undergoes scrutiny under both the CAP (College of American Pathologists) Hair criteria and compliance with ISO/IEC 17025 standards.

Limitations:
Note: Commonly dubbed "hair follicle tests", this procedure evaluates 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.
