Accredited Drug Testing offers comprehensive hair follicle drug tests in Freeman, South Dakota. When hair drug or alcohol testing is needed, we specialize in these tests, having testing facilities nationwide that carry out hair tests. Generally, 1.5 to 2 inches of scalp or body hair may be required. Hair testing can detect drugs, alcohol/ETG, along with other custom hair testing services.
In recent times, hair follicle drug tests have become a standard in drug testing methods. A growing number of employers, legal systems, and substance abuse experts are opting for hair drug tests over the traditional urine test. Hair follicle tests are chosen by employers with strict drug policies, legal systems, and individuals on probation. Hair tests offer an extended duration for detection, up to 90 days, through an observed collection process, making them difficult to manipulate. However, urine tests remain the most accurate for detecting drug use within the past 5 days.

Hair testing has emerged as a robust method for identifying drug and alcohol consumption. Hair serves as a long-term record of alcohol and drug presence by encasing biomarkers within the fibers of a developing strand. When collected near the scalp, hair can deliver up to a 3-month window for detecting alcohol and drugs. It is straightforward to gather, challenging to tamper, and easy to transport.
A 1.5-inch section of around 200 hair strands (roughly the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, which is the ideal amount for screening and affirmation. For EtG tests, add-ons, and/or evaluations above 10 panels, a sample size of 150mg is advisable. Using a jeweler’s scale for weighing the sample is recommended. Should scalp hair be unavailable, an equivalent quantity of body hair is acceptable. References to head hair imply only scalp hair, while body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial processing of a specimen into a lab’s system. This step ensures the sample is sealed and shipped correctly, allocates a random LAN (Laboratory Accessioning Number), and addresses any additional data entry absent from an electronic custody system.
Screening constitutes a preliminary examination for drugs. While Screening efficiently rules out drug usage on most samples, a positive finding necessitates confirmation to be valid in legal proceedings. Any samples showing positive signs upon Screening require subsequent confirmation.
For samples indicating positive signs during Screening, further hair is taken from the original sample and readied for Extraction. Here, drugs are extracted at a lower concentration than with other methods (e.g., urine or oral fluid), rendering hair drug testing the most challenging approach to execute.
Verification of any positive screening results is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All apparent positive samples are cleansed before confirmation as necessary. The complete lab process, from Accessioning to Confirmation, is examined under the CAP (College of American Pathologists) Hair designation and adheres to 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.

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.
