Hair Follicle Drug Testing - Blowing Rock, NC

What it is, How it works

The use of hair testing has emerged as an effective method for identifying alcohol and drug consumption. Hair retains biomarker evidence within the strands, offering a historical perspective on drug use. When taken near the scalp, hair can reveal evidence of alcohol and drug use for a period of up to three months. It's easy to gather, resistant to tampering, and convenient for transportation.

A 1.5-inch segment comprising approximately 200 hairs, similar in size to a #2 pencil, ensures an optimal 100mg sample for testing and verification. For EtG or enhanced screenings exceeding 10 panels, a 150mg specimen is advised. Using a jeweler's scale is ideal for weighing the sample. If scalp hair isn't present, body hair of the same quantity may be used. Specifically, "head hair" denotes scalp hair, while "body hair" covers all other types (like facial or axillary hair).

Process Overview

There are four principal stages in laboratory processing for drug test results: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample undergoes initial integration into a laboratory's systems. This step confirms the sample's proper sealing and shipment, allocates a random LAN (Laboratory Accessioning Number), and finalizes data entry omitted by electronic custody systems.

Screening serves as a preliminary evaluation for drug presence. Although cost-effective for ruling out drug usage across most samples, court verification requires positive screens to undergo confirmation. Any Screening-flagged samples need secondary validation.

In cases of presumptive positivity in Screening, additional hair is extracted from the original sample for the Extraction process. Here, drugs are isolated from hair at lower concentrations than other methods (such as urine or oral fluid), highlighting the complexity of hair drug screenings.

For positive screen verification, GC/MS, GC/MS/MS, or LC/MS/MS techniques are employed. If needed, positive samples are cleansed before confirmation. The complete lab process, from Accessioning to Confirmation, is reviewed under the framework of both the College of American Pathologists' Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Enduring detection window: Hair tests trace drug use for up to 90 days, outlasting the shorter window found in urine tests.
• Immunity to deception: Cheating a hair drug test is notably difficult, enhancing result reliability.
• Usage history: It delineates drug use trends over time, not limiting results to recent consumption.

Limitations:

• Inability to detect recent usage: Drugs require about 5-7 days before becoming traceable in hair.
• Expense: Hair drug testing tends to be pricier compared to other methods.
• Result variability: Hair color and individual growth patterns may influence drug metabolite presence in hair.

Note: Referred to as "hair follicle tests," these tests actually examine the hair strand, not the subscalp hair follicle.

Why Hair Follicle Testing Beats Urine Testing
