Accredited Drug Testing offers comprehensive hair follicle drug examinations in Lums Chapel, Texas. If a hair drug or alcohol assessment is required, we specialize in hair analysis and have facilities across all major cities nationwide to conduct such tests. Typically, 1.5 to 2 inches of hair from the scalp or body is sufficient. Hair samples can be tested for drugs, alcohol/ETG, or tailored testing options.
Over recent years, drug analysis methods have increasingly leaned towards hair follicle examinations. Many employers, judicial bodies, and Substance Abuse experts prefer hair testing over conventional urine analysis. Hair follicle tests cater to organizations with strict drug-free policies, legal entities, and individuals under supervision. The key advantage of this procedure is its extended detection window, typically reaching up to 90 days, collected through a monitored process, making it highly tamper-resistant. Yet, urine testing remains most accurate for identifying recent drug intake within five days.

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 detecting drug and alcohol consumption. Hair retains a long-term record of alcohol and other drugs by trapping chemical markers within the fibers of the growing strand. When collected near the scalp, hair can reveal a detection window of up to three months for drug and alcohol use. The collection of hair is straightforward, it is relatively resistant to tampering, and it can be easily transported.
A 1.5-inch segment containing approximately 200 strands of hair (roughly the diameter of a #2 pencil) from the area closest to the scalp provides 100mg of hair, which is the optimal sample size for initial screening and confirmation. For EtG, additional analyses, and tests exceeding 10 panels, a specimen of 150mg is advisable. Utilizing a jeweler's scale for weighing the specimen is recommended. In cases where scalp hair is not available, an equivalent quantity of body hair is suitable for collection. "Head hair" specifically refers to scalp hair, while "body hair" encompasses all other hair types (such as facial, axillary, etc.).
Process Overview
Key steps in processing a drug test result in the lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial placement of a sample into a laboratory's tracking system. This step includes verifying the sample's seal and proper shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not handled by an electronic chain of custody.
Screening offers a preliminary assessment for drug presence. While Screening is a cost-effective means to exclude drug use in most samples, any positive findings require further verification to be court-admissible. Samples that test presumptively positive during Screening necessitate a secondary confirmation.
If a sample tests presumptively positive in the Screening phase, additional hair is extracted from the initial sample and prepared for Extraction. Drugs are extracted from hair at much lower concentrations than other methods (e.g., urine or oral fluid), making hair drug testing one of the most challenging methodologies to execute.
Confirmation of any positive screening result occurs through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results undergo washing before confirmation if required. The entire laboratory process, from Accessioning to Confirmation, adheres to the CAP (College of American Pathologists) Hair standards and the accreditation of ISO / IEC 17025.
Advantages of hair drug testing:
Limitations:
Note: Commonly called "hair follicle tests," these assessments analyze the hair strand itself, not the hair follicle beneath the scalp.

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.
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.
