In Alexandria, Minnesota, Accredited Drug Testing offers comprehensive hair follicle drug testing. Specializing in hair and alcohol testing, we provide services in all cities across the nation. For a hair test, we require 1.5 to 2 inches of hair, preferably from the crown, although body hair can also be used. Our hair tests can identify drugs, alcohol/ETG, or be tailored for specific requirements.
The hair follicle drug test has become a more prevalent method for drug testing recently. Employers, courts, and substance abuse experts often mandate a hair test over traditional urine analysis. This method is favored by organizations with zero-tolerance drug policies and is used for probation cases. The test's key advantage is its longer detection period, up to 90 days, and the observed collection process ensures a reliable result. Nonetheless, for recent drug use detection, urine tests remain the most precise.

Hair testing has emerged as a significant tool in detecting drug and alcohol consumption. By embedding biomarkers within the growing hair fiber, hair records an extended timeline of alcohol and other drug use. When hair is collected near the scalp, it can offer a detection window stretching up to roughly 3 months for both alcohol and drugs. Hair collection is straightforward, relatively tamper-resistant, and easy to transport.
Obtaining a 1.5-inch hair sample consisting of approximately 200 strands (about the thickness of a #2 pencil) closest to the scalp yields 100mg, the optimal sample size for both screening and confirmation. For EtG, add-ons, and tests beyond 10 panels, collecting 150mg of the specimen is suggested. It is advisable to weigh the specimen using a jeweler’s scale. If scalp hair cannot be sourced, an equivalent amount of body hair may be used. Head hair refers specifically to scalp hair, whereas body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result consists of four essential steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a sample within a laboratory system. This includes validating that the sample was correctly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not handled by an electronic chain of custody system.
Screening involves a preliminary quick assessment for substances of abuse. Although Screening offers a cost-effective method to rule out drug usage in most samples, a positive screen requires confirmation for court admissibility. Samples that are presumptively positive in Screening necessitate further confirmation.
If Screening yields a presumptive positive result, additional hair is extracted from the initial sample and prepared for Extraction. During Extraction, drugs are drawn from hair at a far lower concentration than other methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to execute.
Confirmation of any positive screening result is undertaken using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples are washed before confirmation as necessary. The entire laboratory procedure, from Accessioning to Confirmation, is examined under both the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although often labeled as "hair follicle tests", the test analyzes the hair strand itself and not the hair follicle beneath the scalp.

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.
