In Lake Elmo, Minnesota, Accredited Drug Testing offers thorough hair follicle drug assessments. If you're in need of either hair drug or alcohol screenings, we are experts in hair analyses, with facilities present in every city across the country capable of administering these tests. Typically, 1.5 to 2 inches of hair from the crown or body suffices. Hair evaluations can detect drugs, alcohol/ETG, or be tailored for other testing necessities.
Lately, the prevalence of hair follicle drug tests has surged among drug screening methods. Numerous employers, judiciary bodies, and addiction specialists are opting for hair drug tests over traditional urine tests. These tests cater to employers enforcing zero-drug tolerance policies, the courts, and individuals on probation. A significant advantage of hair follicle testing is its extended detection timeframe, typically reaching up to 90 days, alongside an observed collection method, making it nearly impossible to manipulate. Nevertheless, when it concerns detecting recent drug use within five days, urine tests remain unparalleled.

Hair tests are increasingly recognized as an effective means to detect drug and alcohol consumption. Hair offers an extensive timeline of substance use by embedding biomarkers along the fibers of a developing hair strand. If taken near the scalp, hair samples can show drug and alcohol usage for up to around three months. Hair collection is straightforward, hard to tamper with, and convenient to transport.
An ideal hair sample involves a 1.5-inch length of about 200 strands (comparable to a #2 pencil width) nearest to the scalp, yielding 100mg, which is optimal for testing and verification. For EtG, extended tests, and panels above 10, 150mg of hair is advised. It's best to weigh the sample with a jeweler’s scale. In the absence of scalp hair, a similar amount of body hair can be taken. When mentioning head hair, it specifically refers to scalp hair, whereas body hair covers all other types (facial, underarm, etc.).
Process Overview
The lab processing of a drug test result consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial integration of a sample into the lab’s system, confirming proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data not captured by an electronic chain of custody.
Screening is a swift initial assessment for substances of abuse. Although it's a cost-efficient method to eliminate drug usage for the majority of samples, a positive screening needs confirmation for court admissibility. Presumptive positives from Screening necessitate secondary verification.
For samples deemed presumptively positive during Screening, more hair is extracted from the initial sample and processed in the Extraction stage. Here, drugs are isolated from hair at notably lower concentrations compared to methods like urine or saliva testing, highlighting why hair drug screening is a challenging method.
To confirm any positive screening result, methods such as GC/MS, GC/MS/MS, or LC/MS/MS are utilized. Samples that show presumptive positives are washed before confirmation when necessary. The complete laboratory journey, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Note: While commonly termed as "hair follicle tests", the analysis actually examines the hair strand, excluding 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.
