Accredited Drug Testing offers comprehensive hair follicle drug testing services in Farragut, Tennessee. Specializing in this method, we cater to individuals needing hair-based tests for drugs or alcohol. With locations across various cities nationwide, we require a hair length of 1.5 to 2 inches for testing. Besides drugs, our tests can assess alcohol levels or offer tailored testing options.
Over recent years, drug testing methods have increasingly adopted hair follicle drug tests. Organizations such as employers, courts, and Substance Abuse experts prefer this over traditional urine tests. These tests are preferred by those with zero-tolerance policies, legal authorities, and those under probationary terms. Its main advantage is a longer detection window, typically up to 90 days, with collection under supervision to prevent fraud. However, urine tests remain more accurate for detecting recent drug use within a 5-day timeframe.

Recognized as a potent method, hair testing serves effectively in identifying drug and alcohol consumption. It offers a comprehensive history by capturing biomarkers within the fibrous structure of the hair as it grows. When sampled near the scalp, hair offers an approximate three-month detection period for various substances. The collection process is straightforward, making it challenging to tamper with and easy to transport.
A sample measuring 1.5 inches with around 200 hair strands (roughly the thickness of a #2 pencil) nearest to the scalp provides 100mg, which is optimal for both initial screening and subsequent confirmation. For EtG, additional tests, or those exceeding 10 panels, a specimen of 150mg is advisable. It is suggested that the specimen be weighed using a jeweler’s scale. Should scalp hair be inaccessible, a similar quantity of body hair can be used. "Head hair" specifically refers to scalp hair. "Body hair" includes all other varieties (like facial or axillary hair).
Process Overview
Lab processing for a drug test result comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to integrating a sample into the lab’s system initially. This step ensures proper sealing and transportation of the sample, assigns a unique LAN (Laboratory Accessioning Number), and completes any supplementary data entry absent in an electronic chain of custody.
Screening serves as a preliminary rapid assessment for substance misuse. Though cost-effective for dismissing drug use in numerous samples, a confirmed screen is mandatory for legal acceptance. Samples preliminarily positive in Screening necessitate further verification.
Specimens preliminarily positive in Screening undergo additional hair extraction from the original sample, preparing for the Extraction phase. This phase isolates drugs at notably lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug analysis the most challenging methodology.
Positive screening findings are authenticated through GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, presumptive positive samples undergo washing where necessary. The complete lab process, from Accessioning to Confirmation, adheres to the CAP (College of American Pathologists) Hair designation alongside ISO / IEC 17025 accreditation standards.
