Hair Follicle Drug Testing - Tallulah, LA

What it is, How it works

Hair analysis is increasingly recognized as an effective method for determining both drug and alcohol usage. The hair captures long-term substance use history by encasing biomarkers within the hair strand's growing fibers. When hair samples are obtained close to the scalp, they can offer a detection timeframe of up to roughly three months for both alcohol and other substances. Hair collection is straightforward, not easily tampered with, and simple to transport.

A sample measuring 1.5 inches and approximately 200 hair strands (around the thickness of a #2 pencil) taken nearest to the scalp provides 100mg of hair, which is optimal for testing and validation. For EtG assessments, add-ons, or tests exceeding 10 panels, a specimen amount of 150mg is advised. It's suggested to use a jeweler's scale to weigh the specimen. In the absence of scalp hair, an equivalent quantity of body hair may be used. Head hair refers strictly to scalp hair, whereas body hair includes all other hair types (such as facial and axillary hair).

Process Overview

There are four primary steps in the laboratory handling of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning starts with the sample's initial processing into a laboratory system, confirming proper sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and fulfilling any needed additional data entry not covered by an electronic chain of custody system.

Screening involves a preliminary assessment for substance abuse. While cost-effective, a positive screen must be verified to hold up legally. Samples that are initially positive in Screening need to undergo additional confirmation.

For samples flagged as positive during Screening, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are extracted from hair at much lower concentrations compared to other methods (like urine or oral fluids), emphasizing the complexity of hair drug testing.

Confirmation of any initial positive result is done using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, any presumptive positive samples are washed as necessary. The full lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for up to 90 days, unlike urine tests which have a more limited timeframe.
• Hard to tamper with: Hair drug tests are challenging to falsify, enhancing result accuracy.
• Offers historical insight: It reveals drug use patterns over time, not just recent consumption.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair roughly 5-7 days after use.
• Expense: Hair drug tests tend to be pricier compared to other drug testing options.
• Result variations: Elements such as hair color and personal hair growth differences can influence drug metabolite concentration in hair.

Note: Although sometimes termed "hair follicle tests," this test actually examines the hair strand rather than the underlying scalp hair follicle.
