Hair Follicle Drug Testing - Calvin, LA

What it is, How it works

Hair screening has emerged as an effective method for identifying the use of drugs and alcohol. Hair retains a prolonged record of substances by embedding biomarkers within the strands. When collected near the scalp, hair can offer a detection period for substances extending up to roughly 3 months. Hair is easy to gather, relatively resistant to tampering, and straightforward to transport.

A 1.5-inch section of about 200 hair strands (comparable to the width of a #2 pencil) nearest to the scalp supplies 100mg of hair, the optimal amount for analysis and confirmation. For EtG, extra screenings, and/or examinations exceeding 10 panels, 150mg of the sample is advised. Using a jeweler’s scale to weigh the sample is suggested. If scalp hair isn't accessible, an equivalent body hair amount might be utilized. "Head hair" pertains specifically to scalp hair. "Body hair" includes all other hair categories (facial, axillary, etc.).

Process Overview

The procedure for processing a drug test outcome comprises four critical stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the incorporation of a sample into a lab’s framework. This step involves confirming that the sample was appropriately sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data entries not captured by an electronic custody chain.

Screening is an initial rapid evaluation for substance abuse. While Screening is a cost-efficient method to eliminate drug presence in most samples, any positive results require confirmation for legal admissibility. Presumptively positive Screening samples demand further confirmation.

Upon presumptive positivity during Screening, additional hair is extracted from the original sample and readied for Extraction. In this phase, drugs are withdrawn from hair at a much lower concentration compared to other techniques (e.g., urine or oral fluid), which makes hair drug analysis the most challenging technique to perform.

The Confirmation step for any positive screen result utilizes GC/MS, GC/MS/MS, or LC/MS/MS. Pre-confirmation, all presumptive positive samples are cleansed as necessary. The complete lab process from Accessioning to Confirmation is evaluated in accordance with both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can identify drug use for up to 90 days, whereas urine tests have a shorter detection window.
• Challenge to compromise: The high difficulty in compromising a hair drug test enhances the precision of results.
• Historical usage pattern: It can reveal a usage pattern over an extended period, not just recent consumption.

Limitations:

• Inability to detect recent use: It requires about 5-7 days for substances to become traceable in hair.
• Expense: Hair drug testing generally incurs higher costs compared to other methods.
• Result variances: Factors like hair color and individual growth differences can influence the metabolite concentration in hair.

Note: Despite being referred to as "hair follicle tests," the test evaluates the hair strand rather than the scalp's follicle.
