Hair Follicle Drug Testing - North Star, DE

What it is, How it works

The perception of hair testing has evolved into an effective method for identifying drug and alcohol consumption. Hair offers a comprehensive timeline of exposure to alcohol and drugs by encapsulating biomarkers within the strands as they grow. If collected close to the scalp, hair can reveal substance use over a roughly 3-month timeframe. Its collection is straightforward, tampering is challenging, and it is easily transportable.

A sample taken from 1.5 inches of about 200 hairs (approximately the diameter of a #2 pencil) nearest to the scalp yields 100mg, ideal for both preliminary screening and detailed confirmation. For assessments involving EtG, extra tests, or panels exceeding 10, a 150mg specimen is advised. Utilization of a jeweler’s scale for weighing the sample is recommended. If scalp hair is not obtainable, an equal volume of body hair can be used. References to head hair specifically mean scalp hair. Body hair encompasses all other types (e.g., facial, axillary, etc.).

Process Overview

The laboratory workflow for processing drug test samples includes four steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning handles a sample’s initial integration into a lab's system, ensuring it was adequately sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any remaining data entry absent from an electronic chain of custody.

Screening provides a preliminary evaluation for substance misuse. Though cost-efficient for eliminating negatives in most samples, results needing legal validation require a confirmatory test. Screen positives mandate a secondary confirmation step.

Should a sample test positive during Screening, additional hair from the original sample is processed during Extraction. Here, drug extraction from hair occurs at significantly lower concentrations than other methods (such as those using urine or oral fluid), which complicates hair drug screening execution.

Confirmation uses GC/MS, GC/MS/MS, or LC/MS/MS techniques to verify any preliminary positive results. Each sample marked presumptively positive undergoes cleansing before confirmation as necessary. The complete process, from Accessioning through Confirmation, is scrutinized under both CAP (College of American Pathologists) Hair designation and the accreditation of ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair testing identifies drug use up to 90 days prior, exceeding the shorter range of urine tests.
• Tampering resistance: Hair tests are particularly hard to manipulate, ensuring result integrity.
• Tracks substance history: The method illustrates a user’s drug pattern over time, beyond immediate usage.

Limitations:

• Inability to detect immediate use: Drugs become traceable in hair after approximately 5-7 days.
• Expense: Hair testing tends to be pricier than alternative testing options.
• Variability in outcomes: Result concentrations can vary due to factors like hair color and individual growth differences.

Note: While commonly misidentified as "hair follicle tests," the analysis targets hair strands rather than follicles beneath the scalp.
