Accredited Drug Testing provides comprehensive hair follicle drug assessments in Norris, Tennessee. If obtaining a hair drug or alcohol test is essential, our expertise in this area, with numerous centers Nationwide, ensures seamless testing. Typically, a sample of 1.5 to 2 inches of hair from the scalp or body is required. Our tests can examine drugs, alcohol/ETG, or other bespoke options tailored to your needs.
Over the years, hair follicle drug testing has become a preferred method for substance detection. Mandated by many employers, courts, and substance abuse experts, this method is increasingly replacing traditional urine tests, especially among zero-tolerance employers and in probation assessments. Its advantage lies in detecting drug use over a 90-day period, collected under observation, rendering tampering nearly impossible. However, for recent drug use (within 5 days), urine tests still hold the upper hand.

Hair analysis is now regarded as an effective method for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and drug intake by locking in biomarkers within the strands' fibers as they grow. Collected near the scalp, hair can indicate drug or alcohol use for up to roughly three months. Collection is straightforward, altering is challenging, and transportation is convenient.
A sample measuring 1.5 inches of roughly 200 hair strands (akin to a #2 pencil's thickness) near the scalp yields 100mg, the optimal quantity for testing and validation. For EtG, additional checks, and/or tests beyond ten panels, a quantity of 150mg is advisable. Utilizing a jeweler’s scale for weighing the sample is suggested. If scalp hair isn't available, a comparable quantity of body hair may be used. "Head hair" specifically denotes scalp hair, while "body hair" encompasses all other varieties (facial, axillary, etc.).
Process Overview
The primary stages in the laboratory analysis of a drug sample include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial entry of a sample into a laboratory's system, ensuring the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and finalizing any extra data entry not covered by an electronic chain of custody system.
Screening is the initial quick evaluation for drug presence. While Screening is efficient for excluding drug use in most samples, a positive result requires confirmation for court admissibility. Samples showing preliminary positive results in Screening need further verification.
If a sample shows presumptive positivity during Screening, additional hair is taken from the initial sample to prepare for Extraction. During Extraction, drugs are retrieved from hair in significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening exceptionally challenging.
Any positive screening outcome is validated via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivity are laundered before confirmation if necessary. The complete lab process from Accessioning to Confirmation adheres to CAP (College of American Pathologists) Hair guidelines and ISO/IEC 17025 standards.
