Accredited Drug Testing provides thorough hair follicle drug assessments in Witten, South Dakota. If a hair drug or alcohol analysis is needed, Accredited Drug Testing offers expert hair assessments, and features centers in all major cities nationwide for conducting such tests. Typically, 1.5 to 2 inches of hair from the head or body is required. These tests can detect drugs, alcohol/ETG, or can be tailored for specific testing needs.
Lately, drug testing methods increasingly favor hair follicle tests. Many workplaces, judicial systems, and substance abuse experts mandate hair drug assessments over traditional urine tests. Hair tests are chosen when zero-tolerance policies are in place or for individuals on probation. The key advantage of hair testing is its extended drug use detection, usually covering up to 90 days, observed during collection, and challenging to deceive. Nevertheless, urine tests remain the standard for detecting recent drug use within 5 days.

Hair testing is increasingly recognized as a robust method for detecting drug and alcohol consumption. Hair captures a long-term record of alcohol and drug use by embedding biomarkers within the strands of hair as they grow. Collecting hair close to the scalp allows up to about a 3-month detection timeframe for alcohol and drugs. Hair is easy to gather, somewhat resistant to tampering, and simple to transport.
A 1.5-inch segment of approximately 200 hair strands (similar to a #2 pencil in size) nearest to the scalp provides 100mg of hair, the optimal sample for screening and confirmation. For testing EtG, additional services, and/or more than 10 panels, 150mg of the sample is advisable. We suggest using a jeweler’s scale to measure the sample's weight. If scalp hair isn't available, a similar amount of body hair can be obtained. References to head hair imply scalp hair exclusively. Body hair includes all other types of hair (such as facial, axillary, etc.).
Process Overview
The laboratory steps in processing a drug test are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial entry of a sample into the laboratory system. This step involves verifying the sample’s proper sealing and shipping, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any additional data input not included by an electronic chain of custody system.
Screening involves an initial evaluation for substances of misuse. Although Screening is a budget-friendly method to exclude drug use in most samples, a positive screening must be confirmed to be admissible in legal settings. Any samples deemed presumptively positive during Screening require a further confirmation process.
If a sample tests presumptively positive in Screening, additional hair is taken from the initial sample for Preparation for Extraction. In this stage, drugs are extracted from hair at much lower levels than in other methods (e.g., urine or oral fluid), which makes hair drug testing one of the most challenging processes to execute.
Confirming any positive screening outcome is done using GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples are washed before confirmation as necessary. The complete laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly called "hair follicle tests", the test actually examines the hair strand, 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.
