Hair Follicle Drug Testing - Libuse, LA

What it is, How it works

Hair testing is now recognized as an effective means for detecting alcohol and drug use. With hair carrying a historical record of substances by capturing biomarkers within its strands, it offers a window of up to three months when taken near the scalp. Hair collection is straightforward, resistant to tampering, and easily mailed.

A sample consisting of a 1.5-inch portion of around 200 hair strands, akin to the thickness of a #2 pencil and situated near the scalp, will yield 100mg, the perfect amount for testing. For EtG additions or panels beyond ten, a 150mg sample is advised. Using a jeweler’s scale for measurement is advisable. If scalp hair isn't accessible, an equivalent mass of body hair may be used. References to head hair specifically mean scalp hair, while body hair encompasses all other types (like facial or axillary hair).

Process Overview

The laboratory processing of drug test results involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the initial step of integrating a sample into the laboratory. It ensures correct sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and finalizes any data entry absent from an electronic chain of custody.

Screening serves as a preliminary assessment for potential drug use. Even though Screening offers a cost-efficient means to eliminate drug use for most samples, any positive test result must be verified for legal admissibility. Samples with positive preliminary results need to undergo further confirmation.

For samples testing positive preliminarily, extra hair from the original sample undergoes preparation for Extraction. In this step, drugs are extracted from hair in much lower concentrations compared to other methods (like urine or oral fluid), which contributes to the complexity of hair drug testing.

Confirmation for any positive result from Screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positives undergo washing before confirmation when necessary. The complete laboratory procedure from Accessioning through Confirmation is thoroughly audited under the CAP (College of American Pathologists) Hair specifications and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection window: Hair tests can reveal drug use over a span of 90 days, unlike urine tests with shorter windows.
• Difficulty to cheat: Hair tests are notably difficult to manipulate, ensuring more precise outcomes.
• Provides historical data: It illustrates patterns of drug use over time rather than just recent occurrences.

Limitations:

• Cannot detect recent use: A timeframe of approximately 5-7 days is required for hair to show drugs.
• Cost: Typically, hair tests are pricier than other drug testing techniques.
• Variations in results: Drug metabolite levels in hair can be influenced by factors like hair color and individual's hair growth variations.

Note: Though commonly termed as "hair follicle tests", the testing is performed on the hair strand itself, not the follicle beneath the scalp.
