Accredited Drug Testing provides comprehensive hair follicle drug testing in Guide Rock, Nebraska. For those seeking a hair drug or alcohol test, Accredited Drug Testing specializes in hair analysis, with testing centers in every city nationwide that can carry out a hair test. Typically, 1.5 to 2 inches of hair either from the crown or body can be used. Hair tests are capable of detecting drugs, alcohol/ETG, or offer other tailored hair testing options.
In recent times, drug testing methodologies have increasingly embraced the hair follicle drug test. This method is favored by many employers, courts, and Substance Abuse specialists over the regular urine test. Hair follicle drug tests are requested by employers adhering to strict drug-free policies, judicial bodies, and individuals on probation. The main advantage of hair follicle tests lies in their extended drug detection window, reaching up to 90 days, witnessed during collection, and are almost foolproof. However, for drug use assessment within the last five days, the urine test remains the most precise.

Hair analysis is now regarded as an effective method for assessing both drug and alcohol consumption. Hair captures a lasting record of alcohol and drug usage by embedding biomarkers within the fibers of the hair as it grows. When obtained near the scalp, hair can reveal up to around a 3-month period of alcohol and drug presence. Hair collection is straightforward, relatively hard to tamper with, and simple to transport.
A 1.5-inch segment of roughly 200 hair strands (akin to the size of a #2 pencil) nearest to the scalp will yield 100mg, which is ideal for screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, a 150mg sample is preferable. We advise using a jeweler’s scale to measure the sample. If scalp hair isn't available, an equivalent amount of body hair can be utilized. The term head hair specifically denotes scalp hair, while body hair encompasses all other hair types (like facial or axillary).
Process Overview
The laboratory processing of a drug test comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a specimen into the lab’s system. This step involves checking the proper sealing and shipping of the sample, allocating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not covered by an electronic chain of custody system.
Screening provides a preliminary assessment for drugs of abuse. Although Screening is a cost-efficient method to eliminate drug usage in the bulk of samples, any positive results must be confirmed for legal admissibility. Any samples presumed positive in the Screening phase necessitate further confirmation.
Should a sample indicate presumptive positivity during Screening, additional hair from the initial sample is processed for Extraction. Here, drug substances are isolated from the hair at much lower concentrations than seen in other testing approaches (such as urine or oral fluid), which makes hair drug testing a complex technique.
For confirming a positive screening outcome, methods such as GC/MS, GC/MS/MS, or LC/MS/MS are employed. All samples with presumptive positivity undergo washing before confirmation if required. The complete laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Limitations:
Note: Although frequently termed as "hair follicle tests", this test evaluates the hair strand, not the follicle beneath the scalp.

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.
