In Rosemont, Nebraska, Accredited Drug Testing offers comprehensive hair follicle drug testing. If you're in need of a hair drug or alcohol test, our expertise lies in hair testing with centers accessible nationwide. Typically, you need 1.5 to 2 inches of hair on your head, or body hair may suffice. Hair tests are eligible for drugs, alcohol/ETG, and other specific testing options.
The methodology for drug testing has increasingly favored hair follicle tests in recent times. Employers, courts, and substance abuse specialists often insist on hair drug tests over standard urine tests. It's preferred by those with zero-tolerance drug policies, like employers and courts, due to longer detection periods of up to 90 days. It's tough to manipulate, though urine tests still best identify drug use within a 5-day span.

Hair assessments are now recognized as a potent method for identifying drug and alcohol usage. Hair offers an extended history of alcohol and other substances by preserving biomarkers within the strands of the hair as it grows. When hair is clipped near the scalp, it offers an approximate detection timeframe of up to three months for alcohol and other substances. Hair collection is straightforward, relatively resistant to tampering, and simple to transport.
A hair sample measuring 1.5 inches consisting of around 200 strands (comparable to the size of a #2 pencil) closest to the scalp yields approximately 100mg of hair, which is the perfect amount for both screening and confirmation. For tests like EtG add-ons or those exceeding 10 panels, a sample weight of 150mg is suggested. We advise utilizing a jeweler’s scale for weighing the sample. In the absence of scalp hair, a matching amount of body hair can be taken. When discussing head hair, we specifically mean scalp hair, whereas body hair indicates all other hair categories (facial, axillary, etc.).
Process Overview
The laboratory processing steps for obtaining a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves incorporating a sample into the laboratory system initially. This process includes checking the seal and shipping conditions of the sample, assigning it a random LAN (Laboratory Accessioning Number), and completing any remaining data entry that the electronic chain of custody system does not cover.
Screening consists of a preliminary examination for drug abuse substances. While Screening offers a cost-efficient method to rule out drug use for most samples, a positive screening result requires confirmation to be valid in court. Samples that are tentatively positive in Screening must undergo further confirmation.
Should a sample show tentative positivity in the Screening phase, additional hair is extracted from the initial sample for preparation for Extraction. At this phase, drugs are separated from the hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), which is why hair drug testing stands out as the most intricate method to perform.
Confirmation of any positive screening result occurs using methods such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples with tentative positivity undergo a pre-confirmation wash as needed. The comprehensive process from Accessioning to Confirmation is scrutinized in line with both the CAP (College of American Pathologists) Hair specifications and the ISO/IEC 17025 accreditation standards.

Note: While commonly called "hair follicle tests", the analysis focuses on the hair strand rather than the scalp-embedded hair follicle.

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.
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.
