Accredited Drug Testing offers extensive hair follicle drug screenings in Harrisburg, South Dakota. If a hair drug or alcohol test is what you need, we're your go-to specialists. We operate centers across the nation skilled in performing these tests. Typically, 1.5 to 2 inches of head or body hair is required. Tests may analyze for drugs, alcohol/ETG, or customized options.
Recently, drug testing methods often utilize hair follicle analysis. Employers, courts, and substance abuse specialists favor hair over urine tests due to the longer detection span of up to 90 days. This method is chosen by entities with zero-tolerance drug policies, making it virtually cheat-proof. Yet, urine tests remain more effective for recent drug use within the last five days.

Hair analysis is recognized as a robust method to detect drug and alcohol consumption. Hair carries a historical record of drug and alcohol usage by capturing biomarkers within the growing hair's fibers. Collected next to the scalp, hair can offer nearly a 3-month period for detecting alcohol and drugs. Hair is straightforward to gather, hard to falsify, and simple to transport.
A 1.5-inch segment of roughly 200 hair strands (about the thickness of a #2 pencil) nearest to the scalp will provide 100mg of hair, which is the preferred sample for initial testing and verification. For EtG, additional tests, and/or tests beyond 10 panels, 150mg of hair is advised. We suggest measuring the specimen with a jeweler’s scale. If scalp hair is unavailable, an equivalent amount of body hair may be collected. When discussing head hair, we refer only to scalp hair. Body hair covers all other hair types (facial, axillary, etc.).
Process Overview
The essential steps in laboratory processing of drug tests are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step in processing a sample within the lab system. This stage includes verifying proper sealing and shipment of the sample, assigning a LAN (Laboratory Accessioning Number) randomly, and completing any additional data not provided by an electronic chain of custody.
Screening is an initial speedy evaluation for substances of abuse. While Screening offers a cost-efficient approach to exclude drug use in most samples, a positive screen must be validated for court acceptability. Any samples that are presumptively positive in Screening must undergo a secondary verification.
Should a sample be presumptive positive during the Screening phase, additional hair is taken from the initial sample for Extraction. In Extraction, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which is why hair drug testing is notably challenging.
Confirmation of any positive Screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned before confirmation as necessary. The entire lab process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:

Note: Although commonly termed "hair follicle tests", the test examines the hair strand and not 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.
