Accredited Drug Testing offers comprehensive hair follicle drug testing services in Livingston, Louisiana. If you're looking for a hair drug or alcohol test, Accredited Drug Testing has expertise in hair evaluations and has facilities across the country that can execute a hair test. Generally, you need 1.5 to 2 inches of hair on your head or body for testing. Hair screenings can detect drugs, alcohol/ETG, or provide tailored hair testing solutions.
In recent years, hair follicle drug tests have increasingly been used as a method for drug testing. Many employers, courts, and substance abuse experts now request a hair test over the traditional urine test. Hair follicle exams are favored by employers with zero-tolerance drug policies, courts, and probationers. The major advantage of a hair follicle drug test is its extended detection duration, typically up to 90 days, collected under observation, making it nearly impossible to be manipulated. However, for assessing drug use in the last five days, urine tests remain the most accurate.

Hair testing has emerged as an effective means for detecting drug and alcohol consumption. By embedding biomarkers within the fibers, hair offers a retrospective view of drug and alcohol use over an extended period. When sampled near the scalp, hair can provide detection insights for up to approximately three months for both alcohol and other substances. Collecting hair is straightforward, somewhat resistant to tampering, and simple to transport.
A 1.5-inch segment of roughly 200 hair strands (approximately the thickness of a #2 pencil) closest to the scalp yields 100mg, which is ideal for screening and confirmation. For EtG, additional analytes, and/or tests beyond 10 panels, a recommendation of 150mg is made. Utilizing a jeweler’s scale for specimen weighing is advised. Should scalp hair not be available, a comparable quantity of body hair may be substituted. References to head hair indicate scalp hair exclusively, whereas body hair pertains to any other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning denotes the initial induction of a sample into a laboratory’s framework. Tasks include ensuring proper sealing and shipment of the sample, allocating an arbitrary LAN (Laboratory Accessioning Number), and filling in any additional data not covered by an electronic chain of custody system.
Screening refers to an initial rapid assessment for drug abuse substances. Though Screening is an economical method to rule out drug presence in most samples, a definitive court-admissible result requires confirmation from a positive screen. Presumptive positive samples in Screening necessitate subsequent confirmation.
Should a Screening stage indicate presumptive positivity, more hair is extracted from the original specimen and prepared for Extraction. In Extraction, drugs are drawn out from hair at significantly lower levels than other procedures (e.g., urine or oral fluid), positioning hair drug screening as the most challenging methodology to execute.
Confirmation of any positive screening outcome occurs through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation, as required. The whole laboratory procedure, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly referred to as "hair follicle tests", the actual analysis targets the hair strand rather than 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.
