In Marshall, Arkansas, Accredited Drug Testing provides thorough hair follicle drug testing. With our expertise in hair testing and a network of centers nationwide, you can easily access a hair drug or alcohol test. A hair length of 1.5 to 2 inches is typically required, and body hair may also be used. These tests can screen for drugs, alcohol/ETG, or be customized based on specific needs.
More recently, drug testing methods increasingly favor hair follicle tests. Many employers, judicial systems, and substance abuse professionals prefer hair tests over standard urine tests. Ideal for zero-tolerance workplaces, courts, and probation scenarios, hair follicle tests offer a longer detection span of up to 90 days, feature observed collections, and are notoriously hard to falsify. However, for detecting recent drug use within 5 days, urine testing remains the gold standard.

Hair analysis has emerged as a vital means for identifying drug and alcohol usage. It offers a prolonged timeline of substance intake by trapping biomarkers within the hair's fibers. When cut close to the scalp, hair can reveal up to a three-month timeframe for alcohol and other drugs. Hair collection is straightforward, challenging to tamper with, and simple to transport.
A 1.5-inch sample comprising around 200 hair strands (approximately the size of a #2 pencil) nearest to the scalp yields 100mg of hair, ideal for both screening and confirmation. For EtG, extra panels, and tests beyond 10 panels, a 150mg sample is advised. It is best to weigh the sample with a jeweler’s scale. If scalp hair isn’t available, the same amount of body hair can be used. When mentioning head hair, it refers solely to scalp hair, whereas body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result consists of four fundamental stages: Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, a sample undergoes initial processing within the lab’s framework. This step ensures the sample was correctly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and finalizes any additional data input omitted by an electronic chain of custody system.
Screening serves as a preliminary check for drug abuse. Although it is cost-effective for eliminating drug usage in most samples, a positive screen requires confirmation for legal admissibility. Samples that are presumptive positive in Screening necessitate further confirmation.
Should a sample be presumptively positive at Screening, additional hair is extracted from the original sample for Extraction. This stage removes drugs from hair at a much lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening the most complex method to perform.
GC/MS, GC/MS/MS or LC/MS/MS methods confirm any positive screening result. All samples presumed positive are cleansed before confirmation if necessary. The complete laboratory procedure from Accessioning through Confirmation is evaluated under CAP (College of American Pathologists) Hair designation and validated against ISO / IEC 17025 standards.

Limitations:
Note: Though often called "hair follicle tests", the examination is conducted on 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.
