Accredited Drug Testing offers comprehensive hair follicle drug testing services in Laurel, Montana. Should you require a hair drug or alcohol test, our expertise is in hair testing, with testing centers available throughout all cities nationwide to conduct hair tests. Typically, 1.5 to 2 inches of hair from the scalp or body is necessary. Hair tests may detect drugs, alcohol/ETG, or other tailored testing options.
Recently, hair follicle drug tests have become a favored method for drug testing. Many employers, judicial systems, and substance abuse experts now prefer them over traditional urine tests. Hair follicle tests are popular with employers enforcing strict no-drug policies, as well as in court and probation scenarios. The key advantage is a longer detection window, identifying drug use for up to 90 days, collected under observation, making it nearly foolproof. Nonetheless, urine tests remain more precise for recent drug usage detection within 5 days.

When you're searching for hair drug testing near me or hair drug testing locations, we provide a simple and convenient process to find a drug and alcohol testing location near you that is certified to provide all of your drug and alcohol testing needs.
Hair testing is recognized as a potent method for detecting drug and alcohol use. Hair captures biomarkers within the fibers, offering a long-term history of alcohol and other drugs. By collecting hair near the scalp, it can provide an approximate 3-month detection window for alcohol and other substances. Collecting hair is straightforward, not easily adulterated, and simple to transport.
A sample measuring 1.5 inches with around 200 hair strands (approximately the size of a #2 pencil) nearest to the scalp yields 100mg of hair, the ideal amount for both screening and confirmation. For EtG, additional tests, or those beyond 10 panels, 150mg is advised. Using a jeweler’s scale to weigh the sample is recommended. If scalp hair is not available, an equivalent quantity of body hair can be used. When discussing head hair, it refers strictly to scalp hair. Body hair encompasses all other forms (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial entry of a sample into a lab's system. This process includes checking the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry missing from an electronic chain of custody system.
Screening involves an initial rapid check for drugs of abuse. While Screening is cost-effective for ruling out drug usage on most samples, a positive screen must be confirmed to be court-admissible. Samples presumptively positive during Screening require additional confirmation.
If a sample tests presumptively positive in the Screening phase, additional hair is extracted from the initial sample for Extraction. At this stage, drugs are extracted from hair at considerably lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening one of the most challenging methodologies.
Confirmation of any positive screening result is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed as necessary before confirmation. The entire process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
Advantages of hair drug testing:
Limitations:
Note: Commonly referred to as "hair follicle tests", these tests analyze 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. 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.
