Accredited Drug Testing provides comprehensive hair follicle drug screening in Carterville, Missouri. If you require a hair drug or alcohol test, our expertise in hair testing is available at centers in every city nationwide. You need 1.5 to 2 inches of scalp or body hair for most testing purposes. Hair tests can screen for drugs, alcohol/ETG, or other specific options.
Recently, hair follicle drug tests have become more prevalent in drug screening. Employers, courts, and Substance Abuse professionals often opt for hair drug tests over traditional urine tests. These tests are favored by strict employers, legal systems, and probationary officers. A key advantage is the prolonged drug detection period of up to 90 days, offering a near foolproof process. Nevertheless, for detecting recent usage within 5 days, urine tests remain the gold standard.

Hair analysis is increasingly regarded as a potent method for detecting alcohol and drug use. Hair stores a prolonged record of substance use by embedding biomarkers within the growing hair fiber. When collected near the scalp, hair can offer up to a three-month detection period for alcohol and drugs. It is straightforward to collect hair samples, quite tough to tamper with, and simple to send.
Collecting a 1.5-inch segment of roughly 200 hair strands (about the width of a #2 pencil) closest to the scalp will yield 100mg, which is ideal for assessment and confirmation. For EtG, additional requests, and/or examinations exceeding 10 panels, a recommended 150mg is needed. We suggest weighing the specimen using a jeweler’s scale. If scalp hair is not available, an equivalent amount of body hair can be gathered. Regarding head hair, we mean scalp hair specifically. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The core phases in the lab processing of a drug test are Accessioning, Screening, Extraction, and Confirmation.
The Accessioning phase includes the initial insertion of a sample into a lab’s records. It encompasses confirming the sample was appropriately sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and filling in any further data entry absent from an electronic custody system.
The Screening stage performs a swift preliminary check for substance abuse. Though Screening is a cost-efficient method to negate drug use in most cases, a positive result must be validated for legal proceedings. Any samples that are suspected positive in Screening necessitate a secondary confirmation.
If a sample is suspected positive during Screening, additional hair is extracted from the original piece and prepared for Extraction. In this phase, drugs are extracted from hair at a notably lower concentration than alternative methods (e.g., urine or oral fluid), which explains why hair drug analysis is the most intricate methodology.
The Confirmation of any positive screening result is accomplished using GC/MS, GC/MS/MS, or LC/MS/MS. All suspected positive samples are cleansed prior to confirmation as required. The entire lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Limitations:
Note: Although commonly termed "hair follicle tests", the examination evaluates 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. 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.
