Accredited Drug Testing provides comprehensive hair follicle drug testing services in Palito Blanco, Texas. If you require testing for drugs or alcohol via hair, Accredited Drug Testing excels in this area, with facilities across all cities Nationwide that can conduct these tests. Typically, 1.5 to 2 inches of hair from the head or body suffices for testing drugs, alcohol/ETG, or other personalized hair analysis options.
The practice of drug testing has largely transitioned to hair follicle testing recently. Many employers, legal bodies, and substance abuse experts forego urine tests in favor of hair testing. These tests favor employers enforcing strict anti-drug policies, judicial systems, and individuals under probation. The greatest advantage of hair follicle testing is its extensive detection window for drug intake—typically spanning up to 90 days. It involves a monitored collection process that is almost impossible to undermine, although urine testing remains most effective for recent drug use within a 5-day timeframe.

Seen as a potent method for identifying drug and alcohol consumption, hair testing offers a comprehensive history of substance use by capturing biomarkers within the hair strand's fibers. When gathered near the scalp, hair can reveal a detection period spanning up to roughly three months for alcohol and drugs. Hair is easy to gather, somewhat challenging to tamper with, and simple to transport.
A 1.5-inch segment containing around 200 hair strands (equivalent to the diameter of a #2 pencil) nearest to the scalp provides 100mg, the optimal sample for both screening and verification. For EtG, add-ons, or analysis beyond 10 panels, a 150mg sample is advised. It is suggested to weigh the sample on a jeweler’s scale. If scalp hair is inaccessible, a similar amount of body hair can be utilized. References to head hair pertain solely to scalp hair. Body hair encompasses all other forms (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four main steps: Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, the sample is initially processed into the laboratory’s system. This step ensures the sample was sealed and dispatched correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any additional information entry absent from an electronic chain of custody system.
Screening is a preliminary quick evaluation for drugs of abuse. While Screening is an economical approach to dismiss drug involvement for most samples, a positive outcome must be validated for court acceptability. Any samples that show presumptive positive results in Screening need a follow-up confirmation.
Should a specimen be presumptively positive in Screening, additional hair is extracted from the original sample and readied for Extraction. During this phase, substances are isolated from hair at a significantly lower concentration than other methods (e.g., urine or oral fluid), which contributes to hair drug screening's complexity as a method.
Confirmation of any positive Screening result requires GC/MS, GC/MS/MS, or LC/MS/MS methods. All presumptive positive specimens are washed before confirmation if necessary. The complete laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the compliance with ISO / IEC 17025 standards.

Note: While often termed "hair follicle tests", the analysis targets the hair strand itself, 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. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations.
