Accredited Drug Testing offers comprehensive hair follicle drug testing in Colleyville, Texas. Whether you require a hair drug or alcohol test, our expertise in hair testing and nationwide centers mean we're ready to assist you. Typically, 1.5 to 2 inches of hair from your head or body can be used for these tests, which can detect drugs, alcohol/ETG, or be tailored for other specific hair test needs.
Recently, the use of hair follicle drug tests has increasingly become the preferred method for drug screening. Employers, court systems, and Substance Abuse professionals are now insisting on hair tests over standard urine screenings. This test is ideal for zero-tolerance environments, legal requirements, and probation checks due to its extensive detection window of up to 90 days, an observed collection procedure, and difficulty to tamper with. Yet, if recent drug use needs to be identified, within the last five days, a urine test remains the most precise.

Hair assessments have gained recognition as a potent means for identifying drug and alcohol consumption. Hair retains a prolonged record of substance use by embedding biomarkers within the strands as they grow. When gathered near the scalp, hair can offer up to a roughly 3-month detection timeframe for alcohol and other drugs. Hair is easy to gather, relatively tough to tamper with, and simple to dispatch.
A 1.5-inch section comprising approximately 200 strands of hair (comparable to the circumference of a #2 pencil) adjacent to the scalp will yield 100mg of hair, the preferred portion for analysis and validation. For EtG, add-ons, and/or analyses exceeding 10 panels, 150mg of the sample is advised. It's suggested to measure the sample using a jeweler’s scale. If scalp hair isn't accessible, a similar quantity of body hair may be obtained. When indicating head hair, it specifically means scalp hair. Body hair encompasses all other hair types, such as facial or axillary hair.
Process Overview
The core phases in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning relates to the primary integration of a specimen into a lab’s framework. This encompasses checking that the specimen was sealed and transported correctly, allocating a random LAN (Laboratory Accessioning Number), and finishing any extra data input not covered by an electronic chain of custody system.
Screening entails an initial swift inspection for drugs of abuse. Although screening offers a cost-efficient method to exclude drug use for most samples, a positive screening must be validated to be legally permissible. Any samples that exhibit a tentative positive in screening necessitate a secondary validation.
If a specimen appears tentatively positive during the Screening phase, additional hair is extracted from the initial sample and processed for Extraction. During this stage, drugs are withdrawn from hair at a substantially reduced concentration than in other methods (e.g., urine or oral fluid), which is why hair drug analysis is the most intricate approach to undertake.
Confirmation of any affirmative screening outcome is undertaken using GC/MS, GC/MS/MS or LC/MS/MS. Samples showing a tentative positive are cleaned before confirmation as required. The complete lab process from Accessioning to Confirmation is evaluated under CAP (College of American Pathologists) Hair designation as well as the ISO / IEC 17025 standards accreditation.
Advantages of hair drug testing:
Limitations:
Note: While frequently dubbed "hair follicle tests," the evaluation itself inspects the hair strand and not the 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. As we embrace these advancements, we pave the way for a safer, healthier society, where drug testing and analysis serve as powerful tools in protecting public health and maintaining integrity in various sectors. The research presented in this special issue will undoubtedly shape the future of drug testing and analysis, fostering collaboration and inspiring further innovation in this crucial area of scientific inquiry.
