Hair Follicle Drug Testing - Yznaga, TX

What it is, How it works

Hair testing is regarded as an effective method for detecting drug and alcohol consumption. Hair archives a prolonged history of alcohol and narcotics by embedding biomarkers within the hair strand's fibers as it grows. When gathered near the scalp, hair offers a detection window for alcohol and drugs of up to about 3 months. Collection is straightforward, tampering is relatively challenging, and shipping is convenient.

A sample of 1.5 inches comprised of around 200 hair strands (roughly the thickness of a #2 pencil) close to the scalp provides 100mg of hair, the optimal amount for testing and verification. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the sample is advisable. Measuring the sample on a jeweler’s scale is recommended. If scalp hair isn't an option, an equal volume of body hair can be used. References to head hair pertain strictly to scalp hair, while body hair encompasses all other types (such as facial, axillary, etc.).

Overview of the Procedure

The lab processing of a drug test result includes four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning starts with integrating a sample into a lab's system. This step confirms proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and fills in any necessary data not supplied by an electronic chain of custody.

Screening is the initial brief verification for drug abuse. Although it's a cost-efficient approach to dismiss drug use in most samples, a positive screen must be verified for court use. Samples that seem positive during Screening need secondary confirmation.

For specimens that test positive during Screening, additional hair is retrieved from the original sample and prepped for Extraction. During Extraction, drugs are isolated from hair at much lower levels than other techniques (e.g., urine or oral fluid), marking hair drug screening as the most challenging method to execute.

Confirmation of any positive screen is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all samples presumed positive are cleaned as required. The complete laboratory workflow, from Accessioning to Confirmation, undergoes evaluation under the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection period: Hair drug testing can identify drug use up to 90 days, unlike urine testing, which has a reduced detection span.
• Hard to falsify: It's significantly challenging to manipulate results of a hair drug test, ensuring higher accuracy.
• Provides past usage data: It illustrates a pattern of drug consumption over time, not just recent usage.

Challenges:

• Incapable of detecting recent usage: Detection of drugs in hair typically takes 5-7 days.
• Expense: Hair drug tests generally cost more than other drug testing techniques.
• Result fluctuations: Drug metabolite concentration in hair can be influenced by aspects like hair color and personal differences in hair growth.

Clarification: Often called "hair follicle tests", these tests actually analyze the hair strand, not the hair follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Yznaga, TX, hair follicle testing surpasses traditional urine tests in numerous aspects. Hair tests offer a much broader detection window, allowing for a more extended history of substance usage.
