In Corvallis, Montana, Accredited Drug Testing offers comprehensive hair follicle drug testing services. If you're in need of a drug or alcohol test using hair samples, we specialize in this method and operate testing facilities across the nation equipped to conduct hair tests. Typically, 1.5 to 2 inches of hair from the head or body can be used. Our tests are equipped to detect drugs, alcohol/ETG, and custom options.
Over recent years, hair follicle tests have increasingly been adopted for drug screening. More employers, courts, and substance abuse experts now prefer these tests over traditional urine tests. This method supports zero-tolerance workplaces, legal settings, and probation requirements. The key advantage is the extended detection period of drug use, up to 90 days, with observed sample collection, offering tamper-resistant results. However, urine tests remain superior for recent drug use within 5 days.

Hair testing has emerged as a formidable method for identifying drug and alcohol consumption. Hair strands preserve a prolongedchronicle of alcohol and drug intake by capturing biomarkers within their fibers. When procured near the scalp, hair can offer about a 3-month detection span for alcohol and drugs. Hair is straightforward to gather, somewhat challenging to tamper with, and convenient to transport.
A 1.5-inch segment comprising around 200 hairs (resembling a #2 pencil's thickness) adjacent to the scalp provides 100mg of hair, which is the optimal sample for examination and validation. For EtG, add-ons, and/or tests exceeding 10 panels, a specimen of 150mg is advisable. We suggest weighing the specimen with a jeweler’s scale. If scalp hair is unavailable, a similar quantity of body hair may be acquired. When mentioning head hair, we are referencing only scalp hair. Body hair pertains to all other hair categories (facial, axillary, etc.).
Process Overview
The four primary stages involved in processing a drug test result in the laboratory include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial sample processing into a laboratory’s system. This involves verifying the sample’s proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and finishing any supplementary data entry not included in an electronic chain of custody system.
Screening entails a preliminary swift assessment for drugs of abuse. Even though Screening is cost-effective for negating drug use in most samples, a positive result requires confirmation to be court-admissible. Any samples preliminarily positive during Screening necessitate secondary verification.
If a sample is preliminarily positive during the Screening phase, additional hair is obtained from the initial specimen and prepped for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), illustrating why hair drug screening is the most challenging technique to execute.
Confirmation of any positive Screening outcome is conducted using GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumptive positives are washed before confirmation as needed. The complete laboratory process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Drawbacks:
Note: While frequently called "hair follicle tests", the analysis is conducted on the hair strand and not the follicle beneath the scalp.
In Corvallis, MT, hair follicle testing outperforms urine tests by offering distinct advantages.

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.
