Accredited Drug Testing offers comprehensive hair follicle drug testing in Dilley, Texas. For those needing a hair drug or alcohol test, Accredited Drug Testing is proficient in hair testing, with centers located in all cities nationwide capable of conducting a hair test. Generally, 1.5 to 2 inches of hair from the crown or body can be used. Hair tests can be tailored to detect drugs, alcohol/ETG, or other requirements.
Recently, drug testing methods have increasingly incorporated hair follicle tests. Many employers, judiciary bodies, and substance abuse experts now mandate these tests over urine tests. Employers with strict no-drug policies, courts, and probation individuals frequently utilize hair follicle tests. A chief advantage is the extended detection window for drugs, up to 90 days, using an observed collection method that is nearly impossible to manipulate. Yet, for detecting drug use within 5 days, urine tests remain the most precise.

Utilizing hair tests has emerged as an influential method for spotting drug and alcohol consumption. Hair offers an extensive timeline of alcohol and drug intake by embedding biomarkers within the fibers of the maturing hair strand. When collected near the scalp, hair can reveal up to roughly a 3-month detection window for alcohol and drugs. Hair is straightforward to gather, somewhat hard to tamper with, and convenient to transport.
A 1.5-inch sample containing about 200 hair strands (roughly the size of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimal sample for both screening and confirmation purposes. For EtG, additional tests, and/or screenings surpassing 10 panels, 150mg of the sample is advised. We suggest weighing the sample with a jeweler’s scale. If head hair is unavailable, an equivalent amount of body hair can be taken. When mentioning head hair, we're specifically talking about scalp hair only. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory's drug test result processing comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the sample's initial processing into the lab's system. This process includes confirming the sample was sealed and dispatched correctly, assigning a random LAN (Laboratory Accessioning Number), and performing any additional data input not supplied by an electronic chain of custody system.
Screening involves a preliminary rapid check for drug abuse. While Screening is an economical method to exclude drug usage in most samples, any positive screen must be validated for court admissibility. Any samples that yield a presumptive positive in Screening necessitate a subsequent confirmation.
For samples showing presumptive positivity in the Screening phase, additional hair is extracted from the initial sample and prepared for Extraction. This phase involves drugs being extracted from hair at substantially lower concentrations than other methodologies (e.g., urine or oral fluid), marking hair drug screening as the most complex methodology to execute.
Confirmation of any positive screen result is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation if required. The entire lab process, from Accessioning to Confirmation, undergoes review under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Limitations:
Note: Often termed as "hair follicle tests", the actual analysis is performed on the hair strand, not the hair 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. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations.
