Accredited Drug Testing provides comprehensive hair follicle drug screening in Centerville, Tennessee. For those requiring a drug or alcohol test via hair sample, our specialty in hair testing is supported by a network of testing centers available in cities nationwide. Typically, 1.5 to 2 inches of hair from the crown or body is needed. These tests screen for drugs, alcohol/ETG, or can be tailored for specific needs.
Recently, the prevalence of hair follicle drug tests has increased in relevance for drug screenings. Agencies such as employers, legal systems, and substance abuse experts are opting for hair tests over traditional urine samples. These tests are ideal for entities with strict no-drug policies, legal frameworks, and probation cases. Key advantages include detection of substances for up to 90 days with witnessed collections and reduced opportunities for manipulation. Nonetheless, urine tests maintain accuracy for recent usage within 5 days.

Hair testing is now regarded as an effective method for identifying drug and alcohol consumption. By embedding biomarkers within the fibers of the growing hair strand, hair provides a lengthy record of alcohol and other substance use. When obtained from near the scalp, hair can offer up to an approximately 3-month period for detecting alcohol and other drugs. Hair collection is straightforward, relatively resistant to tampering, and easy to transport.
A 1.5-inch section containing roughly 200 hair strands (about the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample size for both screening and confirmation processes. For EtG, additional panels, or tests surpassing 10 panels, a 150mg sample is advised. Using a jeweler’s scale for measuring the specimen is recommended. In cases where scalp hair is unavailable, a comparable amount of body hair can be gathered. When mentioning head hair, it specifically refers to scalp hair, whereas body hair encompasses all other types (such as facial, axillary, etc.).
Process Overview
The four primary phases in processing a laboratory drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initiation of processing a sample within a laboratory’s infrastructure. This encompasses ensuring the sample’s proper sealing and shipping, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any outstanding data entry not captured by an electronic handling system.
Screening encompasses an initial rapid assessment for drug abuse indications. Screening is an economical approach to exclude drug usage for the majority of samples; however, any positive findings in Screening must be validated for legal admissibility. Samples that yield a presumptive positive in Screening require further confirmation.
In cases of a presumptive positive result during the Screening stage, additional hair is extracted from the original sample for preparation in the Extraction phase. In this phase, drugs are extracted from hair at significantly lower concentrations compared to other methods (for example, urine or oral fluid), making hair drug screening the most challenging methodology to execute.
The confirmation of any positive screening outcomes is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumptive for positive results undergo washing before confirmation as necessary. The entire laboratory process, spanning from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and accredited according to ISO / IEC 17025 standards.
