Accredited Drug Testing offers comprehensive hair follicle drug evaluations in Powell Valley, Tennessee. For those requiring a hair drug or alcohol analysis, our specialization is in hair testing, with testing centers available across all U.S. cities capable of performing such tests. Generally, 1.5 to 2 inches of hair from the crown or body is needed. Hair analyses can include drugs, alcohol/ETG, or other specific test selections.
In recent times, drug testing practices have increasingly involved hair follicle analyses. Employers, judicial systems, and substance abuse specialists often prefer a hair drug evaluation over traditional urine assessments. Such tests are ideal for employers enforcing strict drug policies, courts, and probation individuals. The chief advantage lies in the extended detection period of up to 90 days, under monitored collection, rendering them nearly tamper-proof. Nonetheless, urine analyses remain superior for detecting drug use within the past 5 days.

Hair testing is increasingly acknowledged as an effective method for detecting drug and alcohol consumption. The hair strands capture biomarkers within their fibers, allowing for a prolonged tracking of alcohol and drug use. When hair is sampled close to the scalp, it can reveal up to a 3-month usage history for alcohol and drugs. Collecting hair samples is simple, it’s relatively tamper-resistant, and convenient to transport.
A 1.5-inch sample, consisting of roughly 200 hair strands (comparable to a #2 pencil’s thickness), will yield 100mg of hair, deemed optimal for both screening and confirmation. For EtG, additional analyses, and tests beyond 10 panels, 150mg of the sample is preferred. Measuring the specimen’s weight using a jeweler’s scale is advisable. If scalp hair cannot be obtained, a similar quantity of body hair is a suitable alternative. By head hair, we specifically mean scalp hair. Body hair denotes all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result includes four key processes: Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, the sample is initially processed into a lab’s system. This phase ensures the sample was correctly sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and inputs additional data not covered by an electronic chain of custody system.
Screening provides a preliminary assessment for drug use. While Screening is an economical method to exclude drug use in the majority of samples, legally approving a positive screen requires confirmation. Samples showing presumptive positivity in Screening necessitate further confirmation.
Upon presumptive positivity during Screening, additional hair is extracted from the initial specimen for the Extraction phase. Here, drugs are extracted from hair at lower concentration levels than other methods (like urine or oral fluid), illustrating why hair drug screening is among the most challenging methodologies to execute.
Confirmation of any positive outcome in Screening is pursued via GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples undergo washing as necessary. The complete lab process, starting from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.
