Accredited Drug Testing offers comprehensive hair follicle drug testing services in Gallatin Gateway, Montana. Whether a hair drug or alcohol assessment is required, Accredited Drug Testing is equipped to provide specialized hair testing, with centers available Nationwide. Typically, a minimum of 1.5 to 2 inches of hair is necessary from the head or body to conduct a hair test for drugs, alcohol/ETG, or other tailored options.
In recent times, drug testing commonly incorporates the hair follicle method. More employers, courts, and Substance Abuse experts are opting for hair drug tests over the conventional urine test. Employers enforcing zero-tolerance policies, courts, and individuals on probation often use hair follicle testing. Its main advantage is a prolonged detection window for drug use, usually up to 90 days, with observation during collection, making it almost impossible to manipulate. Nevertheless, for drug use detection within 5 days, urine tests remain the most precise.

Hair analysis is increasingly recognized as an effective method for identifying substance and alcohol use. It offers an extensive timeline of drug use by embedding specific indicators within the hair's fibrous strands as they grow. Collecting hair near the scalp enables a detection timeframe of up to about three months for substances and alcohol. Hair is straightforward to obtain, relatively hard to tamper with, and simple to dispatch.
A specimen length of 1.5 inches with around 200 hair strands (comparable to the thickness of a standard pencil) near the scalp yields about 100mg of hair, serving as the optimal quantity for initial screening and validation. For EtG, additional analyses, and/or tests exceeding 10 panels, a 150mg sample is advised. We suggest measuring the sample using a jeweler’s scale. If scalp hair is not available, a matching quantity of body hair can be utilized. The term "head hair" refers solely to scalp hair. The term "body hair" pertains to all hair excluding that on the scalp (such as facial or underarm hair).
Process Overview
The lab processing of a drug test result incorporates four essential steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning focuses on the initial integration of the sample into the lab’s system. This stage ensures the sample’s proper sealing and shipping, randomizes the Laboratory Accessioning Number (LAN), and finalizes any additional data entry omitted from an electronic custody chain.
Screening acts as a preliminary, rapid assessment for substance misuse. While cost-efficient for excluding drug use in most cases, conclusive courtroom evidence requires a positive screen to undergo further validation. Samples with suspected positive results during Screening necessitate supplementary verification.
When a sample is suspected positive during Screening, more hair is extracted from the original sample and processed for Extraction. In this phase, substances are isolated from hair at much lower levels compared to other testing methods (e.g., urine or saliva), which is why hair drug testing poses the greatest complexity.
Confirmation of any presumed positive result relies on GC/MS, GC/MS/MS, or LC/MS/MS technologies. Samples believed positive are cleansed before verification as deemed necessary. The complete laboratory process, from Accessioning to Confirmation, is evaluated according to the both the CAP's Hair criteria (College of American Pathologists) and ISO / IEC 17025 accreditation standards.

Limitations:
Note: While commonly called "hair follicle tests," the analysis itself examines the hair shaft and 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.
