In Tracy, Minnesota, Accredited Drug Testing is a leading provider of comprehensive hair follicle drug testing. Should you require testing for drugs or alcohol, our company excels in hair testing, with facilities available in every city across the United States. Typically, you need to have 1.5 to 2 inches of hair available from your head or body, as it's generally suitable for the analysis. These tests can screen for substances like drugs, alcohol/ETG, and offer several custom testing solutions.
Hair follicle drug testing has increasingly become the preferred method for screening, particularly among employers, judicial systems, and professionals dealing with Substance Abuse. It's considered superior to the traditional urine tests. Employers with strict no-drug-use policies, courts, and individuals on probation widely adopt these tests. The major advantage of hair follicle testing is its extended detection window for substance abuse, lasting up to 90 days, with the sample collection process being observed and nearly immune to tampering. Nevertheless, for identifying recent drug use within the past five days, urine testing remains the most effective.

Hair testing has become recognized as a potent means for detecting drug and alcohol consumption. Hair captures biomarkers in its growing strands, offering a prolonged history of substance use. When obtained near the scalp, hair can present a detection period of up to about 90 days for alcohol and drugs. It's easy to collect hair, challenging to tamper with, and simple to transport.
A sample measuring 1.5 inches, comprising approximately 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp, provides 100mg of hair, which is ideal for screening and confirming. For EtG testing, add-ons, and/or panels exceeding 10, a specimen of 150mg is advised. It's suggested to weigh the sample with a jeweler’s scale. Should scalp hair be inaccessible, a similar amount from body hair can be used. "Head hair" strictly refers to scalp hair, while "body hair" encompasses all other types like facial and axillary.
Process Overview
Drug test results undergo four primary stages in the lab: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial sample processing into a lab’s system, which includes ensuring proper sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry absent from an electronic chain of custody system.
Screening involves an initial rapid check for abusive drug substances. While Screening is a budget-friendly approach to eliminate drug use in most samples, court-admissible evidence requires confirmation of a positive screen. Presumptive positives from Screening necessitate secondary confirmation.
If detected as positive in the Screening phase, more hair is taken from the original specimen for Extraction. Here, drugs are extracted from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), which makes hair drug screening one of the most challenging methodologies to undertake.
Confirmation of any positive screen is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo washing before confirmation as needed. The comprehensive process, from Accessioning to Confirmation, is evaluated per both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Often called "hair follicle tests", the analysis is on the hair strand rather than 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.
