Accredited Drug Testing provides comprehensive hair follicle drug testing services in Poplar Top, Tennessee. Whether you require a hair drug or alcohol test, our expertise lies in hair testing, and we operate testing centers across all cities in the nation. Typically, 1.5 to 2 inches of hair from the scalp or body is suitable for this test. Hair testing can detect drugs, alcohol/ETG, or be tailored for specific needs.
In recent times, hair follicle drug testing has become increasingly prevalent. Many employers, judicial systems, and substance abuse professionals now prefer a hair drug test over the typical urine test. These tests are particularly favored by those with strict drug-free policies, the judiciary, and probation cases. Hair tests offer a distinct advantage—a longer detection period of up to 90 days, conducted under observation, with minimal risk of tampering. However, for recent drug use within 5 days, urine tests remain most precise.

Hair testing is increasingly viewed as an effective method for identifying drug and alcohol consumption. Hair delivers a comprehensive history of alcohol and drug use by capturing biomarkers within the fibers of the developing hair strand. When samples are collected near the scalp, hair can offer up to a 3-month detection period for alcohol and other substances. Hair is easy to gather, relatively resistant to tampering, and straightforward to transport.
A 1.5-inch segment of approximately 200 hairs (about the thickness of a #2 pencil) closest to the scalp will yield 100mg of hair, which is the preferred sample amount for analysis and verification. For EtG, additional tests, and/or assessments exceeding 10 panels, a 150mg specimen is advised. We suggest measuring the specimen on a jeweler’s scale. If scalp hair is not available, a comparable amount of body hair may be used. When discussing head hair, we refer specifically to scalp hair. Body hair encompasses all other hair types (facial, armpit, etc.).
Process Overview
The primary stages in the lab handling of a drug test sample are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial introduction of a sample into a lab’s database. This process ensures the sample is sealed and dispatched correctly, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any additional data input not covered by an electronic chain of custody.
Screening involves an initial rapid evaluation for abusive substances. Although Screening is an economical method to exclude drug consumption for the bulk of samples, any positive results require confirmation for court admissibility. All samples that test presumptively positive in Screening necessitate further verification.
If a sample tests presumptively positive during Screening, additional hair is extracted from the original sample and prepped for Extraction. At this phase, drugs are retrieved from hair at significantly lower concentrations compared to other techniques (e.g., urine or oral fluid), which is why hair drug analysis is the most challenging method to execute.
Verification of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing before confirmation as needed. The full lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair classification and with accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although frequently called "hair follicle tests", the examination focuses on the hair strand rather than the follicle beneath the scalp.
