In Deville, Louisiana, Accredited Drug Testing offers comprehensive hair follicle drug testing services. If a hair or alcohol test is required, our expertise in hair testing is supported by centers nationwide, capable of administering these tests. Generally, 1.5 to 2 inches of hair from the crown or body are needed. Hair tests can screen for drugs, alcohol/ETG, or be customized for specific requirements.
Recently, hair follicle drug testing has gained traction over traditional methods. Many employers, legal systems, and substance abuse professionals now prefer hair tests over urine tests. Zero-tolerance workplaces and individuals on probation benefit from its extended detection period, identifying drug use up to 90 days with a highly supervised process, reducing attempts of evasion. Yet, for drug use within 5 days, urine tests remain superior.

Hair assays are widely recognized as an effective mechanism for detecting substance and alcohol consumption. Hair captures a prolonged history of alcohol and other substances by embedding biomarkers in the fibers of the growing strand. When collected near the scalp, the hair offers nearly a 3-month range for detecting alcohol and other substances. It is straightforward to collect, somewhat hard to tamper, and easy to transport.
A 1.5-inch section of roughly 200 hair strands (approximately the circumference of a #2 pencil) nearest to the scalp will yield 100mg, the prime amount for assessment and confirmation. For EtG, add-ons, and/or evaluations exceeding 10 panels, 150mg of the specimen is suggested. We advise measuring the specimen on a jeweler's scale. If scalp hair isn't available, a comparable amount of body hair can be used. When referring to head hair, we specifically mean scalp hair only. Body hair encompasses all other hair varieties (facial, axillary, etc.).
Overview of the Process
The four primary stages in the lab analysis of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial processing of a sample into the laboratory’s system. This comprises verifying the sample was adequately sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry absent from an electronic chain of custody system.
Screening involves a preliminary rapid examination for substances of abuse. While Screening is an economical method to exclude drug use in most samples, a positive screen requires confirmation to be valid in court. Any samples presumptively positive in Screening need additional confirmation.
Should a sample be presumptively positive in the Screening phase, more hair is extracted from the original specimen to prepare for Extraction. In this segment, substances are extracted from hair at significantly lower concentrations than other methods (ex. urine or oral fluid), thus making hair drug screening the most challenging method to conduct.
Confirmation of any positive screen result occurs via GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The entire lab procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Note: Although known as "hair follicle tests", the analysis is performed on the hair strand, 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.

I needed a quick drug test for visitation with my children. I called at 6am they answered and set me up with a place a couple miles from my house to go get the test done, that was on Wednesday, I had the results on Friday afternoon and was able to see my kids on Saturday. Thank you for the help!
