Accredited Drug Testing provides comprehensive hair follicle drug testing services in Crossville, Tennessee. If you're in need of a hair drug or alcohol test, Accredited Drug Testing is adept at hair testing, with testing centers across all cities nationwide that can conduct a hair test. A minimum of 1.5 to 2 inches of hair on your head's crown or body is required in most cases. Hair tests can assess drugs, alcohol/ETG, or other custom hair testing options.
In recent years, the method for drug testing increasingly involves a hair follicle drug test. Many employers, courts, and Substance Abuse professionals now request a hair drug test over the traditional urine test. Hair follicle drug tests are favored by employers maintaining zero-tolerance drug use policies, courts, and those on probation. The chief advantage of a hair drug test includes a prolonged detection window, typically reaching up to 90 days, gathered in an observed manner, making it nearly foolproof. However, for detecting drug use within the last five days, urine tests remain the most precise.

Hair assessments have emerged as a robust means for identifying substance and alcohol consumption. Hair offers a long-duration record of alcohol and drug use by embedding biomarkers in the fibers of the growing strand. When gathered near the scalp, it can present an approximate 3-month window of detection for alcohol and drugs. Hair is straightforward to gather, somewhat resistant to alteration, and simple to transport.
A 1.5-inch segment containing approximately 200 hairs (roughly the width of a #2 pencil) nearest to the scalp yields 100mg of hair, which is considered the ideal quantity for screening and confirmation. For EtG, add-ons, and/or tests beyond ten panels, 150mg of the sample is suggested. We advise weighing the sample using a jeweler’s scale. If scalp hair is not available, an equivalent volume of body hair can be gathered. In the context of head hair, our reference is specifically to scalp hair. All other hair types (facial, axillary, etc.) are referred to as body hair.
Process Overview
The four fundamental stages in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning constitutes the initial integration of a sample into a lab’s protocol. This encompasses verifying proper sealing and shipping of the sample, assigning a unique LAN (Laboratory Accessioning Number), and executing any supplementary data entry not covered by an electronic chain of custody process.
Screening involves an initial rapid check for illicit substances. While Screening is a cost-efficient approach to dismiss drug presence in the majority of samples, a positive screening requires confirmation to be valid in legal settings. Any samples that appear presumptively positive during Screening necessitate a secondary verification.
Should a sample reflect a presumptive positive in the Screening phase, additional hair is drawn from the initial sample and prepped for Extraction. This stage involves extracting drugs from hair at a concentration much lower than other techniques (e.g., urine or oral fluid), which is why hair drug testing is regarded as the most challenging methodology to administer.
Confirmation of any positive screening results is undertaken through GC/MS, GC/MS/MS, or LC/MS/MS methods. All presumptive positive samples undergo cleansing before confirmation as necessary. The comprehensive laboratory progression from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair classification and compliance with ISO/IEC 17025 standards.
