Accredited Drug Testing offers thorough drug testing using hair follicle analysis in South Tunnel, Tennessee. Whether a hair drug or alcohol test is needed, they specialize in hair testing and boast testing centers across the country capable of conducting these tests. Typically, 1.5 to 2 inches of hair from the scalp or body can be tested. Tests can detect drugs, alcohol/ETG, or tailored hair analysis options.
In recent developments, hair follicle drug tests have increasingly been adopted for drug testing. Numerous employers, judiciary bodies, and Substance Abuse experts favor a hair drug test over urinary analysis. These tests are favored by entities with stringent no-drug policies, legal systems, and individuals under supervision. A key advantage is their extended detection range for drug usage, often up to 90 days, collected under supervision, making them nearly immune to evasion. Yet, for detecting recent drug use, within 5 days, urine tests remain the most accurate.

Hair examinations are increasingly acknowledged as an effective resource for identifying drug and alcohol usage. Hair keeps a prolonged record of substance intake by encapsulating biomarkers within the growing hair strand's fibers. When cut near the scalp, hair can reveal drug and alcohol consumption data for an estimated duration of 3 months. Collecting hair samples is straightforward, challenging to tamper with, and easily shippable.
A 1.5-inch segment comprising roughly 200 hairs (approximately the thickness of a #2 pencil) closest to the scalp provides 100mg of hair, which is the optimal amount for initial screening and verification. For EtG, additional tests, or analyses exceeding 10 panels, a specimen of 150mg is suggested. It's advisable to measure the specimen with a jeweler’s scale. In the absence of scalp hair, a similar quantity of body hair can be collected. When mentioning head hair, it pertains solely to scalp hair. Body hair encompasses all other hair categories (such as facial, axillary, etc.).
Overview of the Process
The laboratory processing of a drug test result consists of four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the sample's initial entry into a laboratory’s system, ensuring the sample was adequately sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and finalizing any further data entry not furnished by an electronic chain of custody system.
Screening serves as a preliminary examination for the presence of drugs. While it is a cost-effective method to negate drug use in most samples, any positive result from Screening requires confirmation to be legally admissible. Samples that test presumptively positive must undergo a secondary confirmation.
Should a sample test presumptively positive during Screening, additional hair is extracted from the initial sample and readied for Extraction. This phase involves extracting drugs from hair at a significantly reduced concentration compared to other methods (such as urine or oral fluid), making hair drug screening one of the most complex methodologies to execute.
Confirmation for any positive screening outcome is performed through GC/MS, GC/MS/MS, or LC/MS/MS. Samples with presumptive positives undergo washing before confirmation if necessary. The entire laboratory sequence from Accessioning to Confirmation undergoes a review following both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.
Benefits of hair drug testing:
Disadvantages:
Note: Though often termed "hair follicle tests", the test itself evaluates the hair strand, not the follicle beneath the scalp.
