Accredited Drug Testing provides thorough hair follicle drug tests in La Salle, Minnesota. If you require drug or alcohol tests via hair samples, our centers nationwide are equipped to facilitate this. A minimum of 1.5 to 2 inches of hair on the head or body can be used typically. These hair tests can detect drugs, alcohol/ETG, or be customized for specific testing needs.
Recently, drug testing reliably employs hair follicle tests more frequently. Employers, courts, and Substance Abuse professionals are opting for hair tests over traditional urine tests. Hair tests are favored by zero-tolerance employers, the legal system, and probationers. Hair tests offer a longer detection window for drug use, around 90 days, ensuring an observed collection process that's hard to tamper with. However, for detecting very recent drug use, within five days, urine tests remain more precise.

Employing hair testing is recognized as an effective approach for identifying alcohol and drug consumption. Hair carries a prolonged record of substances by embedding biomarkers within the strands as they grow. When collected near the scalp, it can offer nearly a 3-month detection timeframe for alcohol and drugs. Hair sampling is straightforward, challenging to tamper with, and easy to transport.
A 1.5-inch section consisting of roughly 200 hairs (approximately the girth of a #2 pencil) closest to the scalp provides 100mg, ideal for screening and verification. For EtG, additional tests, and/or over 10-panel tests, a specimen of 150mg is advisable. It is recommended to weigh the specimen with a jeweler’s scale. If scalp hair isn’t available, an equivalent amount of body hair may be used. When we refer to head hair, we mean scalp hair exclusively. Body hair encompasses all other hair types (such as facial and axillary).
Process Overview
The lab processing of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning comprises the initial integration of a sample into a lab's database, which includes verifying proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing additional data entry not included in an electronic custody chain.
Screening involves a preliminary assessment for drug presence. While it’s a cost-friendly method to exclude drug usage in most samples, a positive result requires confirmation for court admissibility. Any samples showing presumptive positives in Screening need subsequent confirmation.
Should a sample show presumptive positivity during Screening, more hair is extracted from the specimen and prepared for Extraction. In this stage, drugs are retrieved from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), which is why hair drug screening is the hardest method to execute.
If a screening yields a positive, verification is done using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivity are washed before confirmation when necessary. The complete lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and certification to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly termed as "hair follicle tests," the test actually assesses the hair strand, not the scalp hair follicle.

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.
