In Andrew, Louisiana, Accredited Drug Testing provides comprehensive hair follicle drug testing services. If you require a drug or alcohol hair test, we specialize in such services and boast testing centers across the nation capable of conducting hair tests. Typically, a hair sample of 1.5 to 2 inches from the crown or body is needed. Hair tests can be tailored for drugs, alcohol/ETG, or other specific requirements.
The hair follicle drug test has gained popularity in recent times. Increasingly chosen over traditional urine tests by employers, courts, and substance abuse experts, this method is favored for zero-tolerance policies and probation monitoring. Its main advantage is the extended detection window of up to 90 days, collected through observed methods, making it nearly impossible to tamper with. Still, for identifying drug use within the past five days, urine tests remain more precise.

Hair testing emerges as a robust method for detecting drug and alcohol consumption. Hair retains a prolonged history of substance use by embedding biomarkers within the fibers of the hair strand as it grows. Collected near the scalp, hair offers a detection window of up to around three months for both alcohol and drugs. It is straightforward to collect, relatively resistant to tampering, and easy to transport.
A sample measuring 1.5 inches consisting of approximately 200 hair strands (similar to a #2 pencil in thickness) collected closest to the scalp provides 100mg of hair, the preferred amount for both screening and confirmation. For EtG tests, additional analyses, and/or tests exceeding 10 panels, a specimen of around 150mg is advised. It is recommended that the specimen be weighed on a jeweler's scale. If scalp hair is not available, a comparable amount of body hair can be used. References to head hair specifically pertain to scalp hair, while body hair indicates all other types (such as facial and axillary hair).
Process Overview
The core stages of processing a drug test result in a lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial processing of a sample within a lab system. This step includes confirming that the sample was properly sealed and shipped, assigning a unique Laboratory Accessioning Number (LAN), and completing any necessary data entry not covered by an electronic chain of custody procedure.
Screening serves as an initial swift assessment for substances of abuse. While this stage is cost-effective for ruling out drug use in most samples, a positive screen must undergo confirmation to be valid in legal settings. Samples displaying presumptive positivity during Screening require a subsequent confirmation test.
When a sample shows presumptive positivity during the Screening phase, additional hair is taken from the initial sample and prepared for Extraction. In this phase, drugs are extracted from hair at much reduced concentrations compared to other methods (like urine or oral fluid), which makes hair drug screening one of the most challenging methodologies.
Confirmation for any positive screening is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are washed before confirmation if needed. The entire lab procedure from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair criteria and accredited to ISO / IEC 17025 standards.

Note: Although commonly termed "hair follicle tests", the examination is of the hair strand and 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. 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.
