Accredited Drug Testing provides comprehensive hair follicle drug screening in Alexandria, Tennessee. If a hair drug or alcohol test is required, Accredited Drug Testing excels in hair analyses, with testing facilities across all U.S. cities capable of conducting hair tests. Generally, 1.5 to 2 inches of hair on the head or body is needed. Hair analysis can detect drugs, alcohol/ETG, or offer other tailored options.
Over recent years, the approach to drug screening increasingly involves hair follicle drug tests. Numerous employers, judicial systems, and Substance Abuse specialists are opting for hair drug tests instead of standard urine analyses. Hair follicle drug tests are utilized by employers with strict no-drug use policies, the courts, and probationers. A key advantage of a hair follicle drug test is its extended detection timeframe for drug use, covering up to 90 days, collected under supervision, making it almost tamper-proof. However, for detecting drug use within the past 5 days, urine tests remain the most precise.

When you're searching for hair drug testing near me or hair drug testing locations, we provide a simple and convenient process to find a drug and alcohol testing location near you that is certified to provide all of your drug and alcohol testing needs.
Hair tests have emerged as an effective means for identifying drug and alcohol consumption. Hair provides a prolonged record of substances by capturing markers within the strands as they develop. When taken near the scalp, this type of testing offers up to a three-month window of detection for drugs and alcohol. Hair collection is straightforward, hard to tamper with, and simple to transport.
A 1.5-inch section comprising roughly 200 hair strands (comparable to a #2 pencil's diameter) closest to the scalp yields about 100mg, which is optimal for screening and confirmation tests. For EtG assessments, additional analyses, and/or tests exceeding 10 panels, a 150mg specimen is advisable. It's recommended to use a jeweler’s scale for weighing. In cases where scalp hair isn't available, equivalent body hair can be collected. By head hair, we specifically mean scalp hair. Body hair encompasses all other types (such as facial or axillary hair).
Process Overview
The laboratory assessment for drug tests involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage where the sample is processed into the lab's system. This step verifies proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and includes any extra data entry absent from the electronic chain of custody system.
Screening represents a preliminary test for drug presence. Although cost-effective for eliminating drug use in most samples, any positive screen results must be verified for judicial acceptance. Samples showing a potential positive in Screening require additional confirmation.
For samples indicating a potential positive during Screening, additional hair is extracted and readied for the Extraction phase. Here, drugs are extracted at lower concentrations compared to other methods (e.g., urine or oral fluids), showcasing why hair testing is challenging.
Confirmed positive results undergo GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positives are cleaned before confirmation if necessary. The full lab process from Accessioning to Confirmation is scrutinized following CAP (College of American Pathologists) hair designation and aligns with ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Although often termed as "hair follicle tests", this analysis examines the hair strand itself rather than the follicle beneath the scalp.
