Comprehensive hair follicle drug testing is available through Accredited Drug Testing in Holston Valley, Tennessee. If you require a hair-based drug or alcohol test, our facility is equipped for such tests, with centers nationwide. You'll need 1.5 to 2 inches of hair on your head or body for testing. These tests can check for drugs, alcohol/ETG, or other customized options.
Lately, there has been a shift towards using hair follicle drug tests for screening. More and more employers, courts, and substance abuse professionals prefer these over traditional urine tests. Employers who enforce zero-tolerance policies, courts, and probationers commonly use hair tests. The key advantage is the extended detection window of up to 90 days, collected with direct oversight, making it tamper-proof. However, for drugs used within the last 5 days, urine tests are still the gold standard.

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. By capturing biomarkers within the fibers, hair offers a long-lasting record of alcohol and substance use. When gathered near the scalp, it can yield a detection period of up to around 3 months for various substances. Hair collection is straightforward, hard to tamper with, and convenient to transport.
A 1.5-inch segment of roughly 200 hair strands (approximately the diameter of a #2 pencil) closest to the scalp supplies 100mg of hair, which is the optimal amount for analysis and validation. For EtG, additional tests, or those exceeding 10 panels, a 150mg sample is advised. It's recommended to weigh the sample using a jeweler's scale. In the absence of scalp hair, a similar quantity of body hair can be used. Reference to head hair solely pertains to scalp hair. Body hair includes any other types of hair (facial, axillary, etc.).
Process Overview
The drug testing laboratory procedure is composed of four principal stages: Accessioning, Screening, Extraction, and Confirmation.
Initially, Accessioning involves incorporating a sample into the laboratory's framework. This step ensures the sample was correctly sealed and dispatched, allocates a random LAN (Laboratory Accessioning Number), and finalizes data entry not provided by an electronic chain of custody.
The Screening step is a preliminary, swift assessment for substances of abuse. Although it is an economical technique to exclude drug intake for most samples, a positive screen necessitates validation to be permissible in court. Samples that are likely positive in Screening must undergo further confirmation.
Should a sample yield a presumptive positive in Screening, additional hair is extracted from the initial sample for the Extraction phase. During this phase, the extraction of substances from hair occurs at a much lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug analysis the most challenging technique to execute.
The Confirmation of any positive screen is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. Samples identified as presumptively positive are cleaned before confirmation as necessary. The full laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.
