Accredited Drug Testing offers comprehensive hair follicle drug testing services in Northbrook, Illinois. If you require a hair drug or alcohol screening, our specialty lies in hair analysis. We have centers across the nation equipped to conduct hair testing, provided there is 1.5 to 2 inches of hair on your head or body. These tests can detect drugs, alcohol, ETG, as well as other tailored testing options.
In recent times, the preference for drug test methods has shifted increasingly towards hair follicle analysis. Many businesses, judicial entities, and substance abuse specialists are opting for hair drug testing over traditional urine tests. Employers with rigorous no-drug policies, courts, and probation officers employ this method because of its prolonged detection window, which extends up to 90 days, its monitored collection process, and its resistance to tampering. Nonetheless, for capturing drug use within the last five days, a urine test remains the most precise.

Hair testing has gained recognition as an effective method for identifying substance use, including drugs and alcohol. Hair provides an extended timeline of drug and alcohol use by encapsulating biomarkers within the growing hair strand's fibers. Hair gathered near the scalp can offer an approximate detection window of up to three months for alcohol and various drugs. It is straightforward to collect hair, relatively resistant to tampering, and convenient to ship.
A sample of 1.5 inches consisting of around 200 hair strands (similar in size to a #2 pencil) nearest to the scalp yields 100mg of hair, the perfect quantity for testing and confirmation. For EtG, additional tests, or tests exceeding 10 panels, a 150mg specimen is advisable. We advise weighing the hair sample with a jeweler's scale. Should scalp hair be unavailable, a similar quantity of body hair is an alternative. "Head hair" specifically refers to scalp hair, while "body hair" encompasses all other hair types (such as facial and axillary hair).
Process Overview
The laboratory process for analyzing drug test results consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning initiates the procedure by entering a sample into the lab's system. This step includes confirming that the sample is appropriately sealed and shipped, generating a random LAN (Laboratory Accessioning Number), and completing any missing data entries not covered by an electronic chain of custody system.
Screening conducts a preliminary assessment for drug presence. While screening offers a budget-friendly technique to dismiss drug use in most samples, a positive result necessitates confirmation for legal acceptability. Samples that test presumptively positive during screening require further confirmation.
Samples deemed presumptively positive in the screening phase involve further hair extracted from the initial sample and prepared for the Extraction phase. This phase isolates drugs from hair at lower concentrations than alternative methods (such as urine or oral fluid), making hair drug screening the most complex methodology to conduct.
Confirmation of any positive screening result employs GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive samples undergo washing before confirmation as required. The full laboratory process, from Accessioning to Confirmation, is reviewed under both the CAP (College of American Pathologists) Hair standards and accredited to ISO / IEC 17025 standards.

Note: The commonly used term "hair follicle tests" is a misnomer; the tests analyze 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. 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.
