Accredited Drug Testing offers comprehensive hair follicle drug testing services in Fall Branch, Tennessee. For those in need of hair-based drug or alcohol screening, our centers provide specialized hair testing across all cities Nationwide. Generally, 1.5 to 2 inches of hair from the crown or other body areas is required. These tests can detect drugs, alcohol/ETG, or be tailored for specific hair testing needs.
Over recent years, methods for drug testing have increasingly featured hair follicle assessments. Many businesses, legal entities, and substance abuse experts favor hair testing over traditional urine testing. Hair follicle drug tests are essential for employers with strict no-drug policies and are regularly used by courts and probation officers. The notable advantage of such tests is their ability to detect drug use over a potent 90-day period, through observed collections, making them extremely difficult to manipulate. However, for detecting recent drug use within 5 days, urine tests remain the precision leader.

Hair testing is recognized as an effective method to identify drug and alcohol consumption. Hair retains a long-term record of alcohol and drug use by capturing biomarkers within the strands as they grow. When hair is gathered near the scalp, it offers a detection window of up to about three months for alcohol and other substances. This method of collection is easy to perform, challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches in length and consisting of roughly 200 hair strands (comparable to a #2 pencil in size) close to the scalp yields 100mg of hair, which is ideal for screening and confirmation. For EtG, add-ons, and/or testing beyond 10 panels, a sample of 150mg is suggested. It is advisable to measure the sample's weight using a jeweler’s scale. In the absence of scalp hair, a similar volume of body hair can be collected. When mentioning head hair, it specifically refers to scalp hair. Body hair includes all other hair types (such as facial, axillary, etc.).
Process Overview
The laboratory processing of drug test results involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial handling of a sample as it enters a laboratory’s system. This step entails ensuring the sample was properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data input not available via an electronic chain of custody system.
Screening is a preliminary check for drugs of abuse. While it’s a cost-effective strategy to exclude drug use in most samples, a positive screen must be confirmed for it to be legally valid. Samples that are presumptively positive in Screening need further confirmation.
For samples presumptively positive at the Screening phase, additional hair is extracted from the original sample and prepared for Extraction. During Extraction, drugs are drawn out from hair at significantly lower concentrations than other methods (such as urine or oral fluid), hence making hair drug testing a challenging methodology.
Confirmation of a positive screening result is accomplished using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptively positive are cleaned before confirmation as needed. The entire process, from Accessioning to Confirmation, undergoes review under both the CAP (College of American Pathologists) Hair designation, as well as ISO / IEC 17025 accreditation standards.
