Hair Follicle Drug Testing - Wardville, LA

What it is, How it works

Utilizing hair analysis has become recognized as an effective instrument for identifying drug and alcohol consumption. Hair encapsulates a comprehensive timeline of substances by ensnaring biomarkers in the fibers of the growing strand. When collected near the scalp, hair can offer a detection timeframe of up to roughly 3 months for substances. Hair collection is straightforward, relatively resistant to tampering, and convenient for transport.

A sample of roughly 1.5 inches comprising about 200 strands near the scalp equates to 100mg, the preferred quantity for assessment and validation. For EtG, additional features, and/or tests exceeding 10 panels, a recommendation of 150mg is noted. It is advisable to utilize a jeweler’s scale for specimen measurement. In the absence of scalp hair, an equivalent volume of body hair is an acceptable alternative. References to head hair imply solely scalp hair. The term body hair encompasses all other hair types (facial, axillary, etc.).

Process Summary

The laboratory assessment of a drug test result encompasses four fundamental stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the initial integration of a sample into a laboratory's protocol. This comprises confirming the sample’s proper sealing and shipment, assigning a randomized LAN (Laboratory Accessioning Number), and executing any supplementary data entry absent from an electronic custody chain.

Screening entails an initial rapid evaluation for substance abuse. This approach offers a budget-friendly method to dismiss drug usage in most instances; however, a positive finding necessitates confirmation to hold up in legal settings. Samples with a presumptive positive status from Screening require further verification.

In scenarios where a sample is judged presumptively positive during Screening, additional hair is extracted from the primary specimen for the Extraction stage. Here, substances are retrieved from hair at a considerably reduced concentration compared to other techniques (such as urine or saliva), hence hair testing is considered the most intricate method.

Confirmation of any affirmative screening outcome is accomplished using GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Before confirmation, all samples preliminarily deemed positive are cleansed as necessary. The entire lab process from Accessioning to Confirmation undergoes review under CAP (College of American Pathologists) Hair specifications and follows ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection period: Hair testing can identify drug consumption for up to 90 days, whereas urine tests feature a more limited detection period.
• Challenge to deceive: Efforts to manipulate hair testing outcomes are notably challenging, thereby yielding more reliable results.
• Delivers historical insights: It can reveal a chronological pattern of substance intake instead of only recent usage.

Constraints:

• Incapable of identifying recent intake: Drugs require about 5-7 days post-use to become recognizable in hair.
• Expense: Generally, hair testing incurs higher costs compared to other testing methods.
• Outcome variability: Elements such as hair pigmentation and personal growth discrepancies can influence metabolite concentration.

Note: Although commonly called "hair follicle tests", the assessment focuses on the strand rather than the follicle situated under the scalp.
