In Grenville, South Dakota, Accredited Drug Testing offers comprehensive hair follicle drug examinations. Specialized in this field, we have facilities nationwide for conducting hair or alcohol analysis. Typically, 1.5 to 2 inches of hair from the head or body is needed. These tests assess drugs, alcohol/ETG, or can be customized.
Hair follicle drug tests have increasingly become a popular method over recent years. They are preferred by many employers, courts, and substance abuse experts over urine testing due to a longer detection window of up to 90 days, making them harder to falsify. For recent drug use under five days, urine tests still provide better accuracy.

Hair analysis is increasingly recognized as a potent method for identifying drug and alcohol consumption. Hair captures a longitudinal record of alcohol and drugs by embedding biomarkers within the fibers of the hair as it grows. When harvested near the scalp, hair offers nearly a three-month detection period for alcohol and drugs. It is easy to gather, relatively challenging to tamper with, and simple to transport.
A sample measuring 1.5 inches, consisting of around 200 hair strands (comparable in size to a #2 pencil) nearest to the scalp, yields 100mg of hair, an optimal amount for testing and verification. For EtG add-ons and tests exceeding 10 panels, a sample of 150mg is advised. Utilizing a jeweler’s scale is recommended to measure the specimen. If scalp hair is lacking, a comparable volume of body hair may be procured. "Head hair" denotes only scalp hair. "Body hair" refers to all alternative hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning signifies the preliminary sample processing into a lab system, which includes ensuring the sample was properly sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and completing any extra data input not covered by an electronic chain of custody system.
Screening provides a swift primary assessment for drug presence. While efficient in dismissing drug usage in most samples, a positive screen must be confirmed to be valid in legal contexts. Samples that show presumptive positives in Screening indeed warrant additional confirmation.
Should a sample yield a presumptive positive during Screening, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are segregated from hair at significantly lower concentrations compared to methods like urine or oral fluid, highlighting why hair drug analysis presents the most complex methodology.
Verification of any preliminary positive results involves GC/MS, GC/MS/MS, or LC/MS/MS. All preliminary positive samples undergo washing before final verification if necessary. The entire lab sequence from Accessioning through Confirmation is scrutinized under the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 standards.

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.
