Accredited Drug Testing offers comprehensive hair follicle drug testing in Crookston, Minnesota. For those needing a hair drug or alcohol test, we at Accredited Drug Testing are experts in hair testing, with centers available for testing in cities across the nation. Typically, 1.5 to 2 inches of hair from your head's crown or body can be used. These tests can evaluate drugs, alcohol/ETG, or provide other personalized hair testing solutions.
In recent years, conducting drug tests has increasingly involved hair follicle drug tests. A growing number of employers, courts, and substance abuse professionals mandate hair drug tests over standard urine tests. Employers with strict no-drug-use policies, as well as courts and probationary programs, frequently use hair follicle tests. The key advantage is a significantly prolonged detection period of up to 90 days, using an observed collection process which is nearly impossible to tamper with. However, for detecting drug use within the past five days, urine tests remain the most precise.

Hair tests are recognized as a potent method for identifying substance use. Hair encases biomarkers over time within the growing strands, offering an extended record of alcohol and drug consumption. When sampled near the scalp, hair can reveal alcohol and drug use within approximately a 3-month timeframe. Hair is uncomplicated to gather, somewhat resistant to tampering, and straightforward to mail.
A 1.5-inch portion, consisting of roughly 200 hair strands (comparable to a #2 pencil's diameter), closest to the scalp, yields 100mg of hair, the optimal amount for screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a 150mg specimen is advisable. We advise using a jeweler’s scale to weigh the specimen. Should scalp hair be inaccessible, a corresponding quantity of body hair can be used. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other variants (facial, axillary, etc.).
Overview of the Process
The laboratory procedures for processing a drug test result consist of four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the sample's initial integration into the laboratory's system. This step verifies the sample's correct sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and concludes any auxiliary data logging not covered by an electronic chain of custody protocol.
Screening comprises a preliminary rapid assessment for substances of abuse. Although Screening is a cost-efficient method for ruling out drug presence in most samples, any positive results must be confirmed for legal validity. Samples showing presumptive positivity in Screening necessitate further confirmation.
In cases where a sample indicates presumptive positivity during the Screening phase, additional hair is taken from the original sample for Extraction. In this step, substances are retrieved from hair at a lesser concentration than with other methods (e.g., urine or oral fluid), underlining hair drug screening as the most challenging methodology.
Positive results from Screening undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if necessary. The comprehensive lab process, from Accessioning to Confirmation, is evaluated per the CAP (College of American Pathologists) Hair guidelines and the ISO / IEC 17025 accreditation standards.

Drawbacks:
Note: Despite being termed "hair follicle tests," the analysis targets the hair strand, not the follicle beneath the scalp.

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.
