Accredited Drug Testing provides comprehensive hair follicle drug screenings in Lockhart, Minnesota. Whether you require a hair drug or alcohol analysis, Accredited Drug Testing excels in this domain, with testing centers spread across all cities Nationwide capable of conducting hair assessments. Generally, 1.5 to 2 inches of hair from your head’s crown or body is needed. Hair examinations can evaluate drugs, alcohol/ETG, or other tailored hair testing options.
Recently, the practice of drug testing increasingly incorporates hair follicle drug evaluations. A significant number of employers, judicial systems, and Substance Abuse experts now favor a hair drug test over conventional urine tests. Hair follicle drug evaluations are leveraged by employers with strict anti-drug policies, judicial authorities, and individuals on probation. A key advantage is the prolonged detection span of hair follicle drug tests, typically extending up to 90 days, collected through an observed method, making them almost impossible to manipulate. Nevertheless, for detecting drug use within the past 5 days, urine tests remain the most precise.

Hair testing has gained recognition as an effective tool for identifying drug and alcohol consumption. Hair offers a long-term record of alcohol and drug use by embedding biomarkers within the fibers of the growing hair strand. When taken close to the scalp, hair can provide a detection window of up to roughly 3 months for alcohol and other drugs. Collecting hair is straightforward, relatively resistant to tampering, and simple to transport.
A 1.5-inch sample of roughly 200 hair strands (about the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal amount for screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a 150mg sample is advised. It is suggested to weigh the specimen using a jeweler’s scale. If scalp hair is not available, the same quantity of body hair may be collected. When mentioning head hair, we specifically mean scalp hair. Body hair includes all other kinds (facial, axillary, and so on).
Process Overview
The key steps in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves initially processing a sample into a laboratory’s system. This step includes verifying the sample was properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any further data entry not covered by an electronic chain of custody system.
Screening involves a preliminary rapid analysis for drugs of abuse. Although Screening is a cost-effective method to rule out drug usage on most samples, a positive screen must be confirmed to be valid in court. Any samples that appear positive in Screening need further confirmation.
If a sample tests presumptively positive in the Screening stage, more hair is extracted from the initial specimen for further Extraction. During this phase, drugs are extracted from hair at much lower concentrations compared to other methods (ex. urine or oral fluid), which makes hair drug screening the most challenging methodology to execute.
Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation if required. The complete lab process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

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.

I needed a quick drug test for visitation with my children. I called at 6am they answered and set me up with a place a couple miles from my house to go get the test done, that was on Wednesday, I had the results on Friday afternoon and was able to see my kids on Saturday. Thank you for the help!
