Serving Thompson's Station, Tennessee, Accredited Drug Testing provides comprehensive hair follicle drug analysis. If you're in need of hair or alcohol testing, we specialize in hair-based screening and have centers ready to conduct these tests Nationwide. At least 1.5 to 2 inches of hair is necessary—either from your head or body. These tests can detect drugs, alcohol/ETG, or be tailored to other specifications.
Increased preference has been given to hair follicle drug tests over recent years. Many employers, judicial systems, and substance abuse experts favor hair testing over traditional urine screening. Ideal for zero-tolerance workplaces or probation requirements, hair testing provides a much longer drug detection window—up to 90 days—collected under supervision and difficult to tamper with. However, for drug use within the past five days, urine tests remain the most precise.

When you're searching for hair drug testing near me or hair drug testing locations, we provide a simple and convenient process to find a drug and alcohol testing location near you that is certified to provide all of your drug and alcohol testing needs.
Hair testing has emerged as an effective method for detecting alcohol and drug use. Hair offers a prolonged history of substance use by capturing biomarkers within the growing hair fibers. When collected near the scalp, hair can reveal an up to 3-month detection window for both alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and easy to transport.
A sample of 1.5 inches consisting of roughly 200 hair strands (comparable to the thickness of a #2 pencil) near the scalp yields 100mg of hair, the optimal sample size for screening and verification. For EtG, additional analyses, and tests beyond 10 panels, it's advisable to use 150mg of the sample. It's recommended to measure the sample on a jeweler’s scale. In the absence of scalp hair, a comparable amount of body hair can be used. The term 'head hair' specifically refers to scalp hair, while 'body hair' pertains to other hair types (such as facial, axillary, etc.).
Process Overview
The core steps in processing a drug test result in the laboratory include Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the sample's initial entry into a laboratory system. This involves confirming that the sample was adequately sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary data entry absent from an electronic chain of custody system.
Screening is a preliminary assessment for drug use. Although Screening offers a cost-effective means to eliminate drug usage for most samples, a positive screen must be verified for court admission. Any samples yielding a presumptive positive in Screening necessitate further confirmation.
If a sample is presumptively positive at the Screening phase, additional hair is extracted from the initial collection for Extraction. Here, drugs are isolated from hair at much reduced concentrations compared to other approaches (like urine or oral fluid), which accounts for the complexities in hair drug screening.
Positive results from screening undergo Confirmation through methods like GC/MS, GC/MS/MS or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as needed. The comprehensive laboratory process, from Accessioning to Confirmation, is evaluated pursuant to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
