In New River, Tennessee, Accredited Drug Testing offers comprehensive hair follicle drug testing services. For those in need of a hair drug or alcohol test, our expertise in hair testing is backed by numerous testing centers across the nation. Typically, 1.5 to 2 inches of head or body hair are required for testing. These hair tests can detect drugs, alcohol/ETG, or be customized for additional analyses.
The trend towards hair follicle drug tests has been on the rise, replacing traditional urine tests in many scenarios, including for employers, courts, and substance abuse professionals. Employers with strict drug policies, along with courts and individuals on probation, find hair tests beneficial. The main advantage lies in their extended detection window of up to 90 days, while urine tests remain more precise for use within the last five days.

Hair analysis is now widely accepted as an effective means for identifying drug and alcohol consumption. Hair captures a long-term record of these substances by retaining biomarkers within the growing hair strand's fibers. When taken near the scalp, hair offers a detection period of up to roughly 90 days for both alcohol and drugs. It is straightforward to gather, somewhat resistant to tampering, and straightforward to transport.
A sample comprising 1.5 inches of around 200 strands (similar in size to a #2 pencil) positioned nearest to the scalp will yield 100mg, which is the optimum quantity for both preliminary screening and confirmatory testing. For EtG, add-ons, and/or screenings exceeding 10 panels, a specimen quantity of 150mg is advisable. We suggest using a jeweler’s scale for accuracy in weighing the specimen. If scalp hair is not available, a comparable amount of body hair can be utilized. "Head hair" specifically denotes scalp hair, while "body hair" refers to all other types (facial, axillary, etc.).
Process Overview
The laboratory steps for processing a drug test result are divided into Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves integrating a sample into the lab's system. This covers the verification of the sample's sealing and proper shipment, the assignment of a random LAN (Laboratory Accessioning Number), and completing any manual data entry not covered by an electronic chain of custody.
Screening entails an initial, quick evaluation for drug presence. It’s an economical method to exclude drug use in most samples, but a positive finding here needs judicial confirmation. Samples that show a presumptive positive in Screening must undergo a secondary confirmation.
In situations where Screening results are presumptively positive, additional hair is extracted from the primary sample for the Extraction phase. Here, drugs are separated from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), making hair drug testing notably challenging.
Confirmation of any positive screening result is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Every sample with presumptive positive results is appropriately washed before confirmation. The complete lab process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and remains compliant with ISO / IEC 17025 accreditation standards.
