Accredited Drug Testing offers comprehensive drug testing using hair follicles in Powells Crossroads, Tennessee. If a hair drug or alcohol test is required, Accredited Drug Testing is adept in hair analysis, with testing centers available nationwide. Typically, 1.5 to 2 inches of hair from the crown or body is required. Hair tests can evaluate for various drugs, alcohol/ETG, or other specialized options.
Recently, the hair follicle method has become more common for drug testing. Many employers, courts, and substance abuse specialists now opt for hair drug tests in favor of traditional urine analysis. Hair follicle tests suit zero-tolerance employers, courts, and probation clients. These tests offer a longer detection period—up to 90 days, are collected under observation, and are challenging to tamper with. Yet, for recent drug use detection within 5 days, urine tests remain more precise.

Hair analysis has emerged as a formidable method for detecting usage of alcohol and drugs. It offers a prolonged history by embedding biomarkers into the hair strands' growing fibers. When gathered near the scalp, it can reveal substance use up to a roughly three-month span. Hair is easy to collect, challenging to tamper with, and straightforward to transport.
A 1.5-inch cutting of nearly 200 hair strands (approximating the size of a #2 pencil) nearest to the scalp yields 100mg, which is optimal for both screening and confirmation. For EtG, supplementary tests, and/or panels exceeding 10, 150mg is ideal. It’s advisable to weigh the hair using a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair can be used. References to head hair pertain solely to scalp hair, while body hair encompasses other types like facial and axillary.
Processing Steps
The core steps in laboratory testing of a drug sample include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary phase where a sample is integrated into a lab's system. This entails ensuring the sample’s proper sealing and shipping, assigning a LAN (Laboratory Accessioning Number), and completing any pending data entry not covered by an electronic chain of custody.
Screening is an initial rapid testing for drugs of abuse. Although Screening is a budget-friendly way to eliminate drug use in most cases, a positive result requires confirmation to be court-valid. Any samples with presumptive positives in Screening must undergo further confirmation.
When a sample tests presumptively positive in Screening, additional hair is taken from the primary specimen for Extraction. During Extraction, drugs are isolated from hair at significantly lower concentrations than in methods like urine or oral fluid, making hair drug testing more challenging.
Positive Screening outcomes are verified via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples are cleaned before confirmation as applicable. Each segment of the lab process, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.

Note: Often labeled as "hair follicle tests", the analysis actually examines the hair strand itself, not the follicle beneath the scalp.
