Hair Follicle Drug Testing - Darco, TX

What it is, How it works

Hair assessments are increasingly acknowledged for their efficacy in identifying substance use. These strands offer an extended record of alcohol and drugs, capturing biomarkers within the hair's fibers. When taken near the scalp, hair presents an approximate three-month detection timeline for alcohol and drugs. Collecting hair is straightforward, challenging to tamper with, and convenient for transport.

A 1.5-inch collection of roughly 200 hair strands (comparable to a #2 pencil's width) next to the scalp yields 100mg, the optimal quantity for both screening and verification. For tests exceeding 10 panels, including EtG and additional ones, 150mg of samples is advised. It's best to weigh the sample using a jeweler's scale. If head hair isn't accessible, an equivalent amount of body hair is acceptable. 'Head hair' refers strictly to scalp hair, while 'Body hair' includes all other varieties (e.g., facial, axillary).

Process Overview

The laboratory evaluation of a drug test encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is initially processed into the lab's system, ensuring its proper sealing and dispatch, allocating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.

Screening executes an initial swift assessment for drug abuse. Although a cost-effective method for excluding drug usage in most samples, a positive screen necessitates confirmation to be court-admissible. Any Screening samples indicating presumptive positivity require subsequent confirmation.

In cases of presumptive positivity during Screening, additional hair is sourced from the initial sample for Extraction. This process involves extracting drugs from hair at much lower concentrations compared to other methodologies (e.g., urine or oral fluid), making hair drug screening highly challenging.

Verification of any positive Screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Any samples with presumptive positivity are cleansed before confirmation as necessary. The complete lab procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accredited standards.

Advantages of hair drug testing:

• Extensive detection timeline: Hair drug analyses can trace drug consumption up to 90 days, unlike urine tests that offer a shorter detection frame.
• Difficult to falsify: Tampering with a hair drug test is notably challenging, ensuring more accurate findings.
• Delivers historical insight: It outlines drug use patterns over time rather than just recent consumption.

Limitations:

• Incapable of identifying recent use: It requires about 5-7 days for substances to manifest in hair.
• Expense: Hair drug tests generally incur higher costs than other testing methods.
• Result variability: Elements such as hair color and individual hair growth differences can influence drug metabolite concentrations within hair.

Note: Although typically referred to as "hair follicle tests", the actual analysis focuses on the hair strand itself, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why is hair follicle testing superior to urine testing in Darco, TX? For starters, it provides greater detection accuracy, offering reliability that traditional urine tests may lack.

Hair testing surpasses urine testing by detecting a broader range of substances over a longer period, showcasing its effectiveness in ensuring a drug-free environment.
