Hair Follicle Drug Testing - Keller, TX

What it is, How it works

Hair analysis is recognized as an effective method for identifying drug and alcohol usage. Hair offers an extended historical record of substance use by encasing biomarkers within the hair strand’s fibers as it grows. When hair is collected near the scalp, it can yield approximately a 3-month detection timeframe for drugs and alcohol. Collecting hair is straightforward, relatively resistant to tampering, and convenient to transport.

A 1.5-inch portion containing approximately 200 hair strands (roughly the thickness of a #2 pencil) closest to the scalp provides 100mg of hair, which is optimal for analysis and further confirmation. For EtG tests, supplementary tests, and tests above 10 panels, 150mg of the hair sample is advised. We suggest utilizing a jeweler’s scale for weighing the sample. In the absence of scalp hair, an equivalent quantity of body hair can be gathered. The term "head hair" specifically denotes scalp hair. "Body hair" refers to any other hair varieties (facial, axillary, etc.).

Process Overview

The drug testing laboratory procedure encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary processing of a sample into a lab's system. This step ensures the sample was properly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and fills in any missing data entry that isn't covered by an electronic chain of custody system.

Screening consists of an initial swift assessment for drugs of abuse. Although Screening is a cost-efficient method to exclude drug use on most samples, a positive result must undergo confirmation to be admissible in legal contexts. Samples with a presumptive positive screening outcome require confirmation through a secondary analysis.

If a sample shows a presumptive positive outcome during Screening, additional hair is extracted from the initial sample and prepped for Extraction. This phase involves extracting drugs from hair at notably lower concentrations than those found in other methods (like urine or oral fluids), illustrating why hair drug testing is a challenging technique to execute.

The Confirmation phase for any positive screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All samples with presumptive positive results are cleansed before confirmation as necessary. The complete lab process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair standard and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection range: Hair drug analyses can reveal drug consumption over a span of up to 90 days, unlike urine tests with a much shorter detection period.
• High resistance to falsification: Cheating on a hair drug test is exceedingly challenging, leading to more reliable outcomes.
• Reveals usage patterns: It provides an overview of drug consumption trends over time, rather than just recent use.

Limitations:

• Incapable of detecting recent consumption: It requires 5-7 days for drugs to become detectable in hair samples.
• Cost: Hair drug assessments tend to be pricier compared with alternative drug testing methods.
• Result variability: Elements including hair color and individual hair growth rates can impact drug metabolite concentrations in hair.

Note: While commonly referred to as "hair follicle tests," the analysis actually focuses on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing
