In Parsons, Tennessee, Accredited Drug Testing offers comprehensive hair follicle drug testing services. If you're in need of a test for drugs or alcohol, we specialize in this type of analysis, with centers available nationwide. Typically, 1.5 to 2 inches of hair from your head or body is required.

Recently, hair follicle drug testing has become a more common method for screening. Preferred by employers, courts, and Substance Abuse professionals, this method is favored over the traditional urine test. Hair follicle tests are utilized by those enforcing strict drug use policies due to their extended detection period of up to 90 days, their observed collection process, and their resistance to tampering. For recent drug use detection (within the last 5 days), urine tests remain the most accurate.

The process of hair testing is now acknowledged as an effective method for identifying drug and alcohol consumption. This is because hair captures a history of alcohol and drug activity by securing biomarkers within its growing strands. When hair is collected near the scalp, it can reveal drug and alcohol use over a period of up to three months. It's easy to gather, challenging to tamper with, and simple to transport.
Taking a 1.5-inch sample containing roughly 200 hair strands (comparable to a #2 pencil's thickness) nearest to the scalp yields 100mg of hair, which is optimal for both screening and confirmation. For tests such as EtG and those exceeding 10 panels, a sample of 150mg is advisable. It's recommended to weigh the hair sample using a jeweler’s scale. If there is no scalp hair available, a similar quantity of body hair can be used instead. Here, head hair specifically denotes scalp hair, whereas body hair encompasses all other hair types, such as facial or axillary hair.
Process Overview
The laboratory processes a drug test across four pivotal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the phase where a sample is initially integrated into a laboratory’s system. This step involves confirming the sample was properly sealed and shipped, assigning it a LAN (Laboratory Accessioning Number), and completing any missing data not covered by an electronic chain of custody.
Screening constitutes a preliminary evaluation for drug presence. It's a cost-efficient strategy to exclude drug use in most cases. However, results indicating a positive screen need a confirmation to be admissible in legal scenarios. Presumptive positives during Screening mandate subsequent confirmation.
Should a sample test positive in Screening, additional hair is extracted from the original specimen to undergo Extraction, during which substances are isolated from the hair at decreased concentration levels compared to other methods (e.g., urine or oral fluids). This makes hair drug testing a substantially challenging approach.
Confirmation follows a positive screening outcome through methods like GC/MS, GC/MS/MS, or LC/MS/MS. Samples presumed as positive undergo necessary washing before confirming. The entire sequence from Accessioning to Confirmation is scrutinized per the CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 standards accreditation.
