Accredited Drug Testing provides comprehensive hair follicle drug examinations in Calhoun, Tennessee. Whether you require a hair drug or alcohol screening, we're specialists in hair analysis, with testing centers located Nationwide. A minimum of 1.5 to 2 inches of hair is necessary from the crown of your head or elsewhere on the body for most cases. The tests can detect drugs, alcohol/ETG, and other specialized hair testing options.
Over recent years, hair follicle drug tests have increasingly become a staple in drug testing. Employers, judicial entities, and Substance Abuse experts demand hair tests over traditional urine screening. Zero-tolerance policy employers, probation officers, and courts use these tests primarily due to their longer drug use detection period—up to 90 days—found through an observed collection, which is significantly resistant to manipulation. Nonetheless, urine tests remain the most reliable for recent consumption occurring within the last 5 days.

Recognized as a robust instrument, hair testing effectively uncovers alcohol and drug usage. The hair, by capturing biomarkers within its strands as they grow, chronicles a long-term history of substance use. When hair is harvested close to the scalp, it offers a detection window of about three months for alcohol and drug use. The collection of hair is straightforward, resistant to tampering, and simple to transport.
The optimal sample size for both screening and confirmation is a 1.5-inch segment consisting of approximately 200 hair strands (comparable to a #2 pencil in size), yielding 100mg of hair. For EtG add-ons and/or tests with more than 10 panels, a 150mg sample is suggested. To ensure accuracy, weighing the sample on a jeweler’s scale is advised. If the scalp hair is missing, an equivalent volume of body hair can be used. "Head hair" refers exclusively to scalp hair, whereas "body hair" encompasses all other hair types (such as facial and axillary).
Process Overview
The laboratory processing of drug test results comprises four essential phases: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a specimen initially enters a lab’s system. This step includes verifying the sample’s proper sealing and shipment, assigning a LAN (Laboratory Accessioning Number) randomly, and completing any left-out data input not covered by an electronic chain of custody system.
Screening is a swift initial evaluation for substances. While being a cost-efficient way to dismiss drug usage in most specimens, a positive screen requires confirmation for legal admissibility. All samples presumed positive in Screening undergo secondary confirmation.
Should a sample test positive at the Screening phase, more hair is extracted from the original sample and readied for Extraction. At this stage, drugs are drawn from hair at far lesser concentrations than in other methodologies (like urine or saliva), contributing to hair drug screening’s complexity and challenge.
Confirmatory tests for positive screen results utilize GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples receive necessary washing. The entire laboratory process from Accessioning to Confirmation undergoes scrutiny under CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Note: Despite being termed "hair follicle tests", the analysis actually examines the hair strand, not the follicle inside the scalp.
