Hair Follicle Drug Testing - French Settlement, LA

What it is, How it works

Hair assessments are now recognized as a substantial approach for identifying the consumption of drugs and alcohol. As hair grows, it captures biomarkers within the strands, offering a prolonged history of substance usage. When gathered near the scalp, hair can demonstrate a detection span of nearly three months for alcohol and drugs. Collection of hair is straightforward, moderately hard to tamper with, and convenient to transport.

A 1.5-inch section of around 200 hair strands (approximately the width of a #2 pencil) closest to the scalp will yield 100mg of hair, which is the preferred quantity for examination and verification. For EtG, additional tests, or examinations exceeding 10 panels, 150mg of hair is advised. It's suggested to measure the sample on a jeweler's scale. If scalp hair isn't accessible, a similar quantity of body hair might be utilized. References to head hair imply scalp hair specifically. Body hair includes all other types (facial, axillary, etc.).

Process Overview

The laboratory handling of a drug test result includes four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the introductory processing of a sample into a lab’s system. This procedure confirms the sample’s proper sealing and shipment, generates a random LAN (Laboratory Accessioning Number), and finalizes any supplementary data entry absent from an electronic chain of custody system.

Screening entails a preliminary swift check for drug abuse. While Screening is a cost-conscious strategy to exclude drug consumption in most samples, a positive reading needs verification to be valid in court. Samples that display a provisional positive in Screening necessitate a subsequent confirmation.

If a sample shows a provisional positive during the Screening phase, additional hair is extracted from the original sample and prepared for Extraction. This phase extracts drugs from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), establishing hair drug screening as the most challenging methodology to conduct.

Verification of any positive screening result employs GC/MS, GC/MS/MS, or LC/MS/MS. All samples identified as presumptive positive are cleansed before confirmation if deemed necessary. The entire laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the certification to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can identify drug consumption for up to 90 days, unlike urine tests which offer a more limited detection timeframe.
• Hard to falsify: Cheating a hair drug assessment is exceedingly difficult, ensuring more precise outcomes.
• Offers sequential data: It provides a usage pattern over time rather than merely indicating recent consumption.

Limitations:

• Incapable of detecting immediate usage: Drugs become noticeable in hair only after about 5-7 days.
• Expense: Hair drug assessments tend to be pricier compared to other drug testing techniques.
• Result disparities: Variations like hair color and differences in an individual's hair growth can influence the concentration of drug metabolites in the hair.

Note: Although commonly called "hair follicle tests," the analysis is conducted on the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In French Settlement, LA, hair follicle testing surpasses traditional urine tests due to superior detection accuracy and reliability. Unlike urine tests, hair tests cover a longer detection window, providing a comprehensive view of drug use patterns.
