Accredited Drug Testing provides comprehensive hair follicle drug testing services in Petronila, Texas. If you're looking for a hair drug or alcohol evaluation, we specialize in hair testing with locations in every city across the nation. To conduct a hair test, 1.5 to 2 inches of hair from the head or body is usually necessary. Hair analysis can detect drugs, alcohol/ETG, or other tailored hair testing features.
Recently, drug testing approaches have increasingly favored hair follicle tests. Various employers, judicial systems, and substance abuse experts now prefer hair drug tests over the conventional urine test. Employers with zero-tolerance drug policies, court systems, and probationers rely on hair testing. The primary advantage is its extended drug detection period, generally up to 90 days, with observed collection making it hard to alter results. Yet, for detecting recent drug use within 5 days, urine tests remain optimal.

The analysis of hair has become recognized as a robust method for identifying drug and alcohol consumption. Hair acts as a repository for these substances by embedding biomarkers within the strands as they grow, offering a timeline of usage. When a sample is obtained near the scalp, it can reveal drug or alcohol exposure over the past three months. Hair is straightforward to gather, challenging to tamper with, and convenient to transport.
Obtaining a 1.5-inch segment of roughly 200 hair strands (comparable in size to a #2 pencil) nearest the scalp yields 100mg, which is the optimal quantity for both initial testing and verification. For tests like EtG, enhancements, or those that involve over 10 panels, a sample size of 150mg is advised. Using a jeweler’s scale to measure the sample is suggested. If scalp hair is absent, an equivalent quantity of body hair can be used. When discussing head hair, we specifically mean scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The process in a laboratory for determining a drug test result consists of four stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed into the lab's system, which includes checking that it was sealed and shipped correctly, assigning a random Laboratory Accessioning Number (LAN), and completing any remaining data entry omitted by an electronic chain of custody system.
Screening provides an initial quick assessment for substance abuse. Though Screening offers a cost-efficient strategy to rule out drug usage in most cases, any positive results in this stage must be confirmed for legal acceptance. Samples yielding a preliminary positive during Screening require additional confirmation.
Upon a presumptive positive from Screening, more hair is extracted from the original specimen for Extraction. In this phase, drugs are isolated from hair at lower concentrations compared to other methods (such as urine or oral fluid), making hair drug analysis particularly challenging.
Confirmation of any positive results obtained during Screening is achieved using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive outcomes are cleansed before confirmation, if necessary. Throughout the whole laboratory process, from Accessioning to Confirmation, the procedures are overseen under both the CAP (College of American Pathologists) Hair specification and the criterion of ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: While commonly known as "hair follicle tests," the analysis targets 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. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations.
