Accredited Drug Testing offers comprehensive hair follicle drug tests in La Crescent, Minnesota. If you're in need of a hair test for drugs or alcohol, our specialized hair testing services are available in all cities across the nation. Generally, hair from the crown of your head, measuring 1.5 to 2 inches, or body hair can be used. These tests provide analyses for drugs, alcohol/ETG, or other customized options.
In recent years, drug testing methods have increasingly utilized hair follicle tests. Employers, courts, and substance abuse experts often prefer hair tests over standard urine tests. Employers with zero-tolerance policies, courts, and individuals on probation frequently use these tests. A key advantage of hair follicle drug tests is their extended detection period, up to 90 days, with the collection process being monitored, making cheating nearly impossible. However, urine tests remain the most accurate for detecting recent drug use within the last 5 days.

Hair analysis is recognized as a robust method for detecting alcohol and drug usage. It locks in biomarkers within the hair fibers throughout the hair's growth, offering an extensive timeline of drug intake. If sampled near the scalp, it reveals a detection window of roughly three months for alcohol and other substances. Hair collection is straightforward, challenging to tamper with, and simple to transport.
A sample consisting of a 1.5-inch length of approximately 200 hair strands (comparable in thickness to a #2 pencil) from the scalp provides 100mg of hair, the preferred example for both initial screening and subsequent confirmation. For EtG, additional tests beyond 10 panels and/or enhancements, it's advisable to have 150mg of the hair specimen. Using a jeweler’s scale for weighing the specimen is advisable. If scalp hair is unavailable, an equivalent quantity of body hair is an alternative. Head hair exclusively refers to scalp hair, while body hair denotes all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result includes four primary stages: Accessioning, Screening, Extraction, and Confirmation.
In the Accessioning phase, the sample undergoes initial processing within the laboratory's system. This encompasses verifying the sample's proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and completing any data entry not automatically provided by an electronic chain of custody system.
Screening provides a preliminary assessment for substances of abuse. Although cost-effective for exonerating the majority of samples from drug use suspicion, positive results in Screening require confirmation for legal admissibility. Samples presumptively positive in Screening necessitate an additional confirmation step.
If Screening suggests a positive result, more hair is taken from the initial sample and readied for the Extraction phase. Here, drug compounds are isolated from hair at concentrations significantly lower than those of alternate methods (e.g., urine or oral fluid), making hair drug screening exceptionally challenging to conduct.
Confirmation of positive screening outcomes is conducted via GC/MS, GC/MS/MS or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as necessary. The entire laboratory process from Accessioning to Confirmation is endorsed under the CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Often described as “hair follicle tests”, the analysis targets the hair strand rather than the follicle beneath the scalp.

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.
