Hair Follicle Drug Testing - Cornelius, NC

What it is, How it works

The utilization of hair testing has emerged as an effective method for identifying alcohol and drug consumption. By embedding biomarkers within the fibers of growing hair strands, hair can reveal a comprehensive history of alcohol and drug exposure. When extracted near the scalp, hair can offer approximately a 3-month detection period for these substances. It's easy to gather, relatively resistant to tampering, and straightforward to transport.

A 1.5-inch sample comprising about 200 strands of hair (around the thickness of a #2 pencil) closest to the scalp yields 100mg, which is the optimal sample size for evaluation and verification. For EtG, add-ons, or tests needing more than 10 panels, a 150mg specimen is advised. We suggest using a jeweler’s scale for specimen weighing. If scalp hair is inaccessible, a comparable portion of body hair can be obtained. When discussing head hair, we exclusively mean scalp hair. Body hair includes all other hair types (such as facial, axillary, etc.).

Process Overview

The main stages involved in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary processing of a sample within a lab’s framework. This consists of confirming that the sample was correctly sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and completing any extra data entry absent in an electronic chain of custody system.

Screening entails an initial rapid inspection for substance abuse. While Screening offers a cost-efficient approach to exclude drug usage for most samples, a positive result must be verified to be acknowledged in legal contexts. Any samples tentatively positive in Screening require additional confirmation.

If any sample is tentatively positive during the Screening phase, additional hair is sourced from the initial sample and readied for Extraction. This phase involves extracting drugs from hair at notably lower concentrations compared to other methodologies (e.g., urine or oral fluids), which is why hair drug screening is one of the most challenging methodologies to execute.

Confirmation for any positive screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples deemed presumptively positive are cleansed before confirmation if necessary. The entire lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation along with accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeline: Hair drug tests can determine drug use for a span of up to 90 days, unlike urine tests that offer a briefer detection timeframe.
• Challenging to manipulate: Manipulating hair drug tests is highly challenging, thereby enhancing result accuracy.
• Historical record: It can map a pattern of substance use over an extended duration, beyond just recent usage.

Limitations:

• Inability to detect recent usage: A span of roughly 5-7 days is needed before drugs become detectable in hair.
• Expense: Hair drug tests generally incur higher costs compared to other drug testing approaches.
• Outcome variance: Aspects like hair color and personal differences in hair growth can influence the concentration of drug metabolites within hair.

Note: Although termed as "hair follicle tests", the examination concerns the hair strand itself, not the hair follicle beneath the scalp.
