Accredited Drug Testing offers comprehensive hair follicle drug testing services in Green Castle, Missouri. If a hair or alcohol test is needed, Accredited Drug Testing excels in this area with testing locations across the country. Typically, 1.5 to 2 inches of hair from the head or body are required. Hair tests are suitable for detecting drugs, alcohol/ETG, or other specific hair test options.
In recent times, hair follicle drug testing has gained traction over traditional methods. Employers, judicial systems, and substance abuse experts opt for hair tests over standard urine samples. This method is favored by organizations with strict no-drug policies, legal entities, and probation officers. Hair tests have a longer detection span, up to 90 days, and are observed when collected, making them hard to compromise. Yet, for drug use within the prior 5 days, urine tests remain precise.

The use of hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair offers an extended timeline of substance use by capturing biomarkers in the hair strand's fibers as it grows. When collected near the scalp, this method can detect alcohol and other drugs within roughly a 3-month period. Collecting hair is straightforward, somewhat tamper-resistant, and easy to transport.
A sample of 1.5 inches, roughly 200 hair strands (similar to the thickness of a #2 pencil) nearest to the scalp, provides 100mg of hair, which is the optimal sample size for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a specimen of 150mg is advised. Using a jeweler’s scale to weigh the specimen is advisable. Should scalp hair be unavailable, an equivalent amount of body hair can be used. The term "head hair" specifically refers to scalp hair, while "body hair" encompasses all other hair types (e.g., facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage where a sample is processed into the laboratory’s system. This step checks that the sample is sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any data entry not covered by an electronic chain of custody system.
Screening is a preliminary check for drugs of abuse. While it is a cost-efficient way to exclude drug usage in most cases, a positive screen must be confirmed to be valid in legal settings. Any samples that are presumptively positive during Screening require further confirmation.
If Screening indicates a presumptive positive, additional hair is extracted from the initial sample for the Extraction phase. Here, drugs are isolated from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), rendering hair drug screening the most challenging methodology.
Confirmation for any positive Screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation if needed. The entire laboratory process, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

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.
