Accredited Drug Testing provides thorough hair follicle drug screening in Only, Tennessee. If a hair drug or alcohol test is required, Accredited Drug Testing is the expert in hair testing, with centers in every city across the country capable of conducting these tests. Typically, 1.5 to 2 inches of hair from the head or body are necessary. Hair tests can detect drugs, alcohol/ETG, or can be tailored for specific requirements.
Recently, hair follicle drug testing has become a more common method for drug screening. Employers, courts, and Substance Abuse professionals are increasingly favoring hair drug tests over standard urine tests. These tests serve employers with strict drug policies, courts, and individuals on probation. The key advantage is the extended detection period of drug use, lasting up to 90 days, is observed securely, and nearly tamper-proof. However, for detecting recent drug use within 5 days, urine tests remain the most precise option.

Hair testing is recognized as an effective means for detecting drug and alcohol use. Hair chronicles long-term alcohol and drug intake by embedding biomarkers within the strands of growing hair. When harvested near the scalp, hair can offer a detection span of up to around three months for alcohol and other substances. Hair collection is straightforward, difficult to tamper with, and easy to transport.
A 1.5-inch section containing approximately 200 hair strands (similar to the width of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample size for screening and verification. For EtG, enhancements, and/or tests exceeding 10 panels, 150mg of the sample is suggested. We advise measuring the sample using a jeweler's scale. Where scalp hair is not possible to collect, an equivalent amount of body hair can be gathered. When we mention head hair, it refers only to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning comprises the foundational processing of a sample into a lab's system. This step ensures that the sample was securely sealed and dispatched correctly, generates a random LAN (Laboratory Accessioning Number), and finalizes any supplementary data entry not included in an electronic chain of custody system.
Screening is an initial, rapid check for substances of abuse. While Screening is an economical approach to exclude drug consumption in most samples, a positive screen necessitates confirmation to be legally acceptable. Samples deemed presumptively positive in Screening require subsequent confirmation.
In the event of a presumptive positive during the Screening stage, additional hair is drawn from the initial sample for Extraction. In this phase, drugs are retrieved from hair at a significantly lower concentration than other methodologies (ex. urine or oral fluid), which explains why hair drug testing is notably complex to conduct.
Every positive screening result undergoes Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation as necessary. The complete laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
