Accredited Drug Testing provides comprehensive hair follicle drug assessments in St. Bethlehem, Tennessee. If you're looking for a hair drug or alcohol assessment, we're experts in this field, with testing centers nationwide capable of executing a hair test. Typically, 1.5 to 2 inches of hair from the scalp or body suffices. These tests can evaluate drugs, alcohol/ETG, or offer personalized hair testing choices.
In recent times, hair follicle drug tests have become a more prevalent method for drug testing. A growing number of employers, legal bodies, and substance abuse specialists now opt for hair drug tests over conventional urine tests. Hair follicle tests are favored by employers with stringent no-drug-use policies, legal systems, and those on probation. Their main advantage is a longer drug detection span, up to 90 days, with an observed collection process, making them hard to tamper with. For drug use within the past 5 days, urine tests remain the most precise.

Hair analysis has gained recognition as an effective means for identifying drug and alcohol consumption. It captures long-term substance use history by embedding biomarkers within the fibers of the growing hair strand. When cut close to the scalp, hair can reveal a detection timeline of up to three months for alcohol and drugs. Hair is straightforward to collect, relatively hard to tamper with, and easy to transport.
A sample measuring 1.5 inches consisting of about 200 strands (around the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, meeting the ideal criteria for both screening and confirmation. For EtG, additional tests, or panels exceeding 10, a 150mg sample is advisable. It's recommended to weigh the sample using a jeweler's scale. If scalp hair is unattainable, an equivalent amount of body hair may be sourced. "Head hair" pertains to scalp hair only, while "body hair" includes all other types like facial and axillary hair.
Process Overview
Processing a drug test in the lab entails four critical steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes initial processing into the lab's system, encompassing verification of proper sealing and shipping, assignment of a random LAN (Laboratory Accessioning Number), and completing any additional data entry not available through an electronic chain of custody system.
Screening provides a preliminary check for drug abuse. While it's a cost-efficient method to exclude drug usage in most samples, any positive screen must undergo confirmation for court acceptance. Samples that test presumptively positive during Screening demand a secondary confirmation.
Should a sample test presumption positive at the Screening stage, additional hair is taken from the initial sample preparing it for Extraction. Here, drugs are extracted from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), accounting for the complexity of hair drug screening.
Confirmation of any positive screening result is performed with GC/MS, GC/MS/MS or LC/MS/MS. Prior to confirmation, all presumptive positive samples undergo washing as necessary. The entire lab process from Accessioning to Confirmation is rigorously reviewed under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
