Accredited Drug Testing provides comprehensive hair follicle drug testing services in Greeneville, Tennessee. For those in need of a hair drug or alcohol analysis, we have nationwide testing centers ready to conduct a hair test. Typically, you will need 1.5 to 2 inches of hair from the crown of your head or body. Hair tests can determine drug and alcohol/ETG use, along with other tailored testing solutions.
Over the years, hair follicle drug testing has become more prevalent for detecting drug use. Many employers, courts, and substance abuse professionals now prefer this method over traditional urine testing. Hair follicle tests serve employers with zero-tolerance policies, courts, and probation clients, offering a longer detection window of up to 90 days, conducted under observed conditions, making it nearly tamper-proof. However, urine tests still lead in detecting very recent (past 5 days) drug usage.
* You must register by phone or online to receive your donor pass/registration prior to proceeding to the testing center. You must bring a valid government issued ID along with the registration/barcode number which was sent to you by email.

The recognition of hair testing as a robust method for detecting drug and alcohol consumption has gained prominence. Hair retains biomarkers within its fibers, providing a comprehensive history of substance use over a prolonged period. When collected near the scalp, hair can yield a detection window of approximately three months for substances like alcohol and drugs. Collection is straightforward, challenging to manipulate, and easily shippable.
Obtaining a 1.5-inch segment containing roughly 200 strands of hair (comparable to the thickness of a #2 pencil) closest to the scalp equates to 100mg, which is the optimally required amount for both screening and confirmation. For EtG, additional analyses, or tests exceeding 10 panels, a 150mg specimen is advisable. It's suggested to measure the sample using a jeweler's scale. When scalp hair is absent, a comparable quantity of body hair might be gathered. By head hair, we mean exclusively scalp hair. Body hair encompasses all other types (e.g., facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial handling of a sample within the laboratory's infrastructure. This stage verifies the proper sealing and shipment of the sample, assigns a unique LAN (Laboratory Accessioning Number), and fulfills any additional data entries absent from an electronic chain of custody system.
Screening offers a preliminary, efficient check for drug abuse. Though a cost-effective means to dismiss drug use in most samples, a positive screen mandates confirmation for legal admissibility. Samples yielding a presumptive positive in this phase necessitate further confirmation.
Should a sample be deemed presumptively positive during Screening, additional hair is extracted from the original specimen for the Extraction phase. This phase retrieves drugs from hair at significantly lower concentrations than methodologies like urine or oral fluid, rendering hair drug screening notably complex.
Confirmation of any positive screening outcome is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing as required before confirmation. The full laboratory procedure, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
