Hair Follicle Drug Testing - Mccoole, MD

What it is, How it works

The method of hair testing is progressively recognized as an effective means for identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol alongside other substances by embedding biomarkers within the strands' fibers as it grows. When obtained near the scalp, hair can offer a detection timeframe of up to roughly three months for alcohol and drugs. Hair is straightforward to gather, relatively resistant to tampering, and conveniently shipped.

A 1.5-inch segment comprising approximately 200 hair strands (akin to the dimension of a #2 pencil) nearest to the scalp yields 100mg of hair, deemed the optimal sample for both screening and confirmation. For EtG, additional testing, and/or evaluations exceeding 10 panels, a 150mg sample is advised. Utilizing a jeweler's scale for specimen weighing is recommended. In the absence of scalp hair, a comparable volume of body hair can be utilized. Any mention of head hair specifically refers to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

Laboratory processing of a drug test result encompasses four major phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a sample into a laboratory's framework. Steps involve ensuring the sample's secure seal and proper shipping, allocating a unique LAN (Laboratory Accessioning Number), alongside finalizing supplementary data entry absent in an electronic chain of custody protocol.

Screening incorporates an initial rapid evaluation for substance abuse. As a budget-friendly method, it aids in excluding drug usage in most cases; however, a confirmed positive screen is essential for legal validity. Any presumption of positivity during Screening necessitates a subsequent confirmation.

Upon a positive indication at the Screening stage, additional hair from the original specimen undergoes preparation for Extraction. Here, drugs are distilled from hair at significantly lower concentrations compared to alternate methodologies (e.g., urine or oral fluid), rendering hair drug testing notably challenging to execute.

Confirmation concerning any positive screening result employs techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo necessary washing prior to confirmation. The complete laboratory procedure from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair requirements and compliance with ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection duration: Hair drug assessments can reveal drug usage for a period reaching 90 days, unlike urine tests with more restricted detection times.
• Challenge to subvert: Successfully circumventing a hair drug test is highly challenging, thereby enhancing result accuracy.
• Displays usage history: It illustrates a timeline of drug consumption over a span of time rather than indicating merely recent usage.

Limitations:

• Absence of recent usage detection: Drugs typically take around 5-7 days to become noticeable in hair.
• Expense: Generally, hair drug evaluations are pricier relative to other testing means.
• Result variations: Elements including hair color and individual disparities in hair development can influence drug metabolite concentrations in hair.

Note: Though occasionally labeled as "hair follicle tests," the evaluation is conducted on the hair strand itself, not the follicle beneath the scalp.
