Accredited Drug Testing offers comprehensive hair follicle drug testing in Saint Nicholas, Minnesota. If you're in need of a hair drug or alcohol test, we specialize in hair testing and provide testing centers in all cities Nationwide capable of conducting hair tests. Generally, 1.5 to 2 inches of hair on the head or body is required. Hair tests can detect drugs, alcohol/ETG, or can be customized for other options.
In recent times, the approach to drug testing increasingly involves a hair follicle method. Many employers, judicial systems, and Substance Abuse experts now often prefer a hair drug test over a typical urine test. Hair follicle testing is ideal for employers with strict anti-drug use policies, the courts, and those on probation. Its primary advantage is a longer drug detection period, reaching up to 90 days, collected in a monitored procedure, and challenging to deceive. Nevertheless, for drug use screening within the past 5 days, urine tests remain most reliable.

The analysis of hair has emerged as an effective mechanism for identifying drug and alcohol consumption. Hair offers an extended timeline of drug use by embedding biomarkers within the strands as they grow. When sampled near the scalp, hair can reveal drug and alcohol use over an approximately 3-month period. The process of collecting hair is straightforward, somewhat resistant to tampering, and convenient for transportation.
A hair sample measuring 1.5 inches and containing around 200 strands (similar in size to a #2 pencil) near the scalp yields approximately 100mg of hair, which is the optimal amount for both screening and confirmation tests. For tests such as EtG, or those exceeding 10 panels, a recommended 150mg should be obtained. It's advisable to measure the specimen using a jeweler’s scale. If head hair is absent, a comparable amount of body hair may be used. References to head hair specifically mean scalp hair, while body hair encompasses all other types (e.g., facial, axillary).
Process Overview
The laboratory steps for processing drug test results include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step where a sample enters a lab's system. It involves verifying proper sealing and shipping, assigning it a LAN (Laboratory Accessioning Number), and completing any extra data entry not handled by an electronic custody chain.
Screening is a preliminary assessment for drug presence. Though cost-effective for excluding drug presence in most samples, a positive result must be confirmed for judicial validity. Samples testing positive initially require additional confirmation.
Should the Screening indicate potential positivity, more hair from the original sample is prepared for Extraction. In this phase, drug traces are extracted from hair at a substantially lower concentration compared to tests like urine or saliva, highlighting hair testing's complexity.
Confirming any positive outcomes from Screening involves methods like GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives undergo washing before confirmation. The entire laboratory process, from Accessioning to Confirmation, is evaluated according to CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Note: The term "hair follicle tests" is often misused, as the analysis targets the hair strand, not the follicle under 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.
