Accredited Drug Testing offers all-encompassing hair follicle drug analysis services in Andover, Minnesota. For individuals seeking hair-based drug or alcohol assessments, our expertise in hair testing is unrivaled, with centers located throughout the entire nation ready to conduct such tests. Typically, 1.5 to 2 inches of hair from either the scalp or body can be used. This test can screen for drugs, alcohol/ETG, or be tailored for other specific hair testing needs.
In recent times, the utilization of hair follicle drug testing has grown considerably as a method for substance analysis. This approach is increasingly favored by employers, judicial systems, and Substance Abuse specialists over traditional urine testing. Hair follicle tests are essential for organizations with strict no-drug policies and are also utilized by courts and individuals under probation terms. The major advantage of hair follicle tests is the extended detection timeframe for substances, which usually spans up to 90 days, mandates an observed collection process, and is exceptionally difficult to deceive. Nonetheless, for substance detection within a recent 5-day window, urine tests remain the most accurate choice.

Hair analysis has become recognized as an effective method for identifying alcohol and drug consumption. The strands of hair encapsulate biomarkers, offering an extended history of substances. When taken near the scalp, the detection period can extend up to roughly three months for alcohol and substances. Hair collection is straightforward, hard to alter, and convenient for transportation.
An ideal sample consists of a 1.5-inch section of around 200 hair strands (similar in size to a #2 pencil), yielding 100mg, perfect for both initial testing and verification. For tests like EtG add-ons or those exceeding 10 panels, a 150mg sample is advisable. We suggest measuring the sample weight with a jeweler’s scale. If head hair isn’t available, a similar amount of body hair can be used. By head hair, we mean hair from the scalp only. Body hair includes other types such as facial or axillary hair.
Process Overview
The process in the lab for drug test results involves four steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts with integrating a sample into the lab system. It checks if the sample is sealed correctly, assigns a unique LAN (Laboratory Accessioning Number), and inputs any missing information not captured by an electronic chain of custody system.
Screening involves a quick drug abuse check. It’s a cost-effective method to eliminate drug usage in most samples, but for court validity, a positive result needs confirmation. Any presumptively positive samples require further confirmation.
If a sample tests positive at the Screening stage, additional hair is extracted from the initial sample for the Extraction phase. Here, substances are extracted at much lower concentrations compared to other methods (e.g., urine or oral fluid), making hair testing the most challenging method to execute.
Confirmation for any positive screening result is done through GC/MS, GC/MS/MS, or LC/MS/MS. All positive samples undergo necessary washes before confirmation. The entire lab process is reviewed from Accessioning to Confirmation, meeting both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly called "hair follicle tests", the analysis actually examines the strand rather than 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.
