Hair Follicle Drug Testing - Pleasant Hill, NC

What it is, How it works

The utilization of hair testing has emerged as an influential technique in recognizing drug and alcohol consumption. Hair effectively records the usage of alcohol and other substances over time by embedding biomarkers within the hair's fibers as it grows. If obtained adjacent to the scalp, hair can reveal drug and alcohol use for roughly a 3-month period. Hair collection is straightforward, challenging to tamper with, and convenient to transport.

A 1.5-inch segment consisting of around 200 hair strands (comparable in size to a #2 pencil) nearest the scalp will provide 100mg of hair, which is the preferred quantity for evaluation and verification. For tests like EtG, additional panels, or those exceeding 10 panels, it is preferable to have 150mg of the hair sample. Using a jeweler’s scale is advised to measure the sample. In instances where scalp hair isn't accessible, an equivalent volume of body hair can be utilized. References to head hair pertain strictly to scalp hair. Body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The primary stages included in the lab handling of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is first integrated into a lab's system. This step reviews if the sample's seal and shipment are intact, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any outstanding data entry not covered by an electronic chain of custody mechanism.

Screening is a preliminary inspection for drug abuse. While cost-efficient for eliminating drug use in most cases, any positive screen needs further verification for legal admissibility. Presumptive positives found in Screening demand additional confirmation.

For samples that show presumptive positivity during Screening, additional hair is extracted from the original batch for Preparation in Extraction. Here, drugs are extracted from hair at a significantly lower density compared to other practices (e.g., urine or oral fluid), rendering hair drug testing the most intricate methodology to execute.

GC/MS, GC/MS/MS, or LC/MS/MS techniques are employed for verifying any positive outcomes from Screening. Required presumptive positive samples are cleansed before confirmation. The entire lab sequence from Accessioning through Confirmation is overseen by CAP (College of American Pathologists) Hair label and adherence to ISO / IEC 17025 criteria.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug testing can identify drug use for up to 90 days, unlike urine tests that have shorter detection spans.
• Hard to manipulate: Hair drug tests are notoriously resilient to deception, enhancing result precision.
• Shows drug use patterns: It reveals long-term drug usage patterns, not merely recent activities.

Limitations:

• Incapable of detecting recent usage: Hair needs about 5-7 days before drugs become apparent.
• Expense: Typically, hair drug tests are costlier than alternative drug testing methodologies.
• Result variability: Discrepancies such as hair color and personal hair growth rate can affect drug metabolite levels.

Note: Although commonly termed "hair follicle tests", the test assesses the strand of hair rather than the follicle beneath the scalp.
