Accredited Drug Testing offers comprehensive hair follicle drug tests in Cowan, Tennessee. Whether it's for drug or alcohol analysis, our specialization in hair testing is supported by a network of facilities across the nation capable of conducting these tests. Typically, hair samples from the crown spanning 1.5 to 2 inches are necessary, or body hair might serve in certain scenarios. Hair tests provide results for drugs, alcohol/ETG, along with other customizable examinations.
In recent times, drug testing procedures increasingly involve hair follicle testing. Employers, judicial systems, and Substance Abuse professionals now favor hair drug testing over traditional urine tests. This method serves those with strict no-drug policies, including court mandates and probationary requirements. Hair follicle testing is advantageous primarily due to its extended drug detection period—often reaching up to 90 days—combined with a monitored collection process that is highly resistant to tampering. However, for substance screening within the immediate past 5 days, urine testing remains superior.

Hair testing has become recognized as an effective method for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and drug use through trapping biomarkers within the strands as they grow. Collected near the scalp, hair offers a detection period of up to three months for alcohol and drugs. It's easy to collect, hard to tamper with, and convenient to transport.
A 1.5-inch portion encompassing roughly 200 strands (similar to the thickness of a #2 pencil) closest to the scalp yields about 100mg of hair, which is optimal for analysis and verification. For EtG, additional tests, or panels exceeding 10, a 150mg quantity is advised. It's best to weigh the sample on a jeweler’s scale. If scalp hair isn't accessible, an equivalent quantity of body hair can be used. "Head hair" refers exclusively to scalp hair. "Body hair" includes all other types (facial, axillary, etc.).
Process Overview
The key stages in laboratory drug test processing include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary handling of a sample into the lab's system, which involves confirming proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.
Screening provides an initial evaluation for potential drug presence. Although cost-effective for ruling out drug use in most samples, a positive Screen result necessitates confirmation to be used evidentially. Any samples suspected to be positive in Screening require a confirmation step.
When a sample tests presumptively positive during Screening, more hair is extracted and prepped for the Extraction process. During this phase, drug components are extracted from hair at far lower concentrations than other methods (e.g., urine or oral fluid), presenting hair drug screening as the most challenging technique to perform.
Positive Screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS analysis. Before confirmation, any presumptive positive samples are cleansed as necessary. The complete laboratory workflow from Accessioning to Confirmation is monitored according to both the CAP (College of American Pathologists) Hair protocol and the ISO/IEC 17025 standards accreditation.
