Accredited Drug Testing provides comprehensive hair follicle drug screenings in Wear Valley, Tennessee. If a hair-based drug or alcohol assessment is required, Accredited Drug Testing is your go-to, with specialized hair tests and numerous centers across the country capable of conducting these tests. Typically, 1.5 to 2 inches of hair from the head or body suffices. Hair tests can determine drug, alcohol (ETG), or other specific requirements.
Recently, hair follicle testing has become a popular choice over traditional methods. Employers, judicial systems, and substance abuse experts now often prefer hair tests over urine tests. This method is favored by companies with zero-tolerance drug policies, legal systems, and probationary programs. Hair tests offer an extended detection period, often up to 90 days, ensuring observation during collection. However, for identifying drug use within five days, urine tests remain the most accurate.

Hair analysis is regarded as an effective method for uncovering drug and alcohol consumption. Hair captures a prolonged record of alcohol and other substances by embedding biomarkers within the strands' fibers. When sourced near the scalp, hair can offer up to a 3-month detection duration for alcohol and drugs. It's easy to collect, moderately challenging to tamper with, and simple to mail.
A 1.5-inch portion of around 200 hair strands (similar in size to a #2 pencil) from the scalp yields 100mg of hair, which is the optimal quantity for screening and confirmation. For EtG, additional tests, and/or those exceeding 10 panels, 150mg of sample is advisable. We suggest using a jeweler’s scale to weigh the sample. If scalp hair is absent, a comparable amount of body hair can be used. By head hair, we mean scalp hair alone. Body hair includes all other hair types (beard, armpit, etc.).
Process Overview
The laboratory processing of a drug test encompasses four core steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial sample processing within a lab's system. This step comprises ensuring the sample was appropriately sealed and shipped, generating a random LAN (Laboratory Accessioning Number), and accomplishing any supplementary data entry needed that isn't covered by an electronic chain of custody system.
Screening involves a preliminary swift review for drugs of abuse. Screening is an economical method for excluding drug use in most cases, yet a positive outcome requires verification to be court-admissible. Samples that appear positive in Screening need a subsequent confirmation.
Should a sample seem positive during the Screening phase, further hair is extracted from the primary specimen and set for Extraction. At this juncture, drugs are extracted from hair at significantly reduced concentrations than through other methods (e.g., urine or saliva), hence hair drug screening poses the utmost complexity.
Confirmation of a positive result from Screening is via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumed positive results undergo washing as required before confirmation. The comprehensive lab process from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

Note: Despite often being termed "hair follicle tests," the test actually evaluates the hair strand, not the follicle below the scalp.
