Accredited Drug Testing provides thorough hair follicle drug assessments in Parmelee, South Dakota. For those requiring a hair drug or alcohol analysis, Accredited Drug Testing is an expert in hair examinations, with facilities available in all U.S. cities to conduct these tests. Generally, 1.5 to 2 inches of head or body hair is necessary. Hair assessments can detect drugs, alcohol/ETG, or offer specialized testing options.
Recently, drug testing methods have more frequently included hair follicle tests. Many companies, legal systems, and substance abuse experts now prefer this over the traditional urine analysis. Zero-tolerance employers, courts, and probation cases regularly use hair tests. The main advantage includes a prolonged drug detection period of up to 90 days, with a supervised collection method that is challenging to manipulate. Nonetheless, for detecting recent drug use within 5 days, urine tests remain the most precise.

Hair analysis is increasingly recognized as a robust method for identifying substance and alcohol consumption. It offers an extended timeline for tracing these substances by integrating biomarkers within the strands of hair as it grows. When sourced from near the scalp, hair provides an estimate of up to around a 3-month period for detecting alcohol and substances. Collection is straightforward, tampering is challenging, and transportation is uncomplicated.
A 1.5-inch segment consisting of about 200 hairs (approximately the diameter of a #2 pencil) nearest to the scalp yields 100mg, the most suitable amount for both initial screening and definitive testing. For EtG, additional tests, and assessments exceeding 10 panels, it is advisable to use 150mg. A jeweler’s scale is recommended to measure the sample weight. If scalp hair cannot be obtained, an equivalent mass of body hair may be used instead. 'Head hair' indicates only scalp hair, while 'body hair' encompasses all other hair types (facial, axillary, etc.).
Process Overview
There are four critical stages in the processing of drug test samples in the laboratory: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into the laboratory system. This step ensures the sample is appropriately sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and completes any outstanding data input not handled by a digital chain of custody process.
Screening serves as a preliminary evaluation for substances of misuse. Although Screening is cost-efficient for dismissing substance usage in most samples, confirmation is necessary for any positive screen to be valid in legal proceedings. Samples indicated as positive during Screening necessitate further verification.
When a sample tests positive during Screening, additional hair from the original sample is set aside for Extraction. Drugs are extracted at a much reduced concentration in this phase compared to other methods like urine or oral fluid, which is why hair drug analysis poses the greatest challenge in execution.
Confirmation of any positive screen result is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Samples indicated as positive are cleansed prior to confirmation when required. The entirety of the lab process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair categorization alongside accreditation 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.
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.
