Hair Follicle Drug Testing - White Lake, NC

What it is, How it works

Hair assessments have emerged as a robust mechanism for identifying alcohol and drug usage. Hair captures a prolonged history of substance consumption by embedding biomarkers within the fibers of the hair strand as it grows. When hair samples are cut near the scalp, they can reveal a detection timeline of up to three months for substances like alcohol and other drugs. Collecting hair samples is straightforward, not easily tampered with, and simple to transport.

An optimal sample comprises a 1.5-inch portion containing roughly 200 hair strands (equivalent to a #2 pencil), yielding 100mg of hair, which is ideal for both screening and validation processes. For EtG, supplemental tests, or tests exceeding ten panels, a 150mg sample is advisable. We suggest using a jeweler’s scale for weighing samples. If hair from the scalp is unavailable, an equal quantity of body hair may serve as a substitute. References to head hair are specifically to scalp hair, whilst body hair pertains to all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the preliminary processing of a specimen into the lab's system, ensuring the sample was securely sealed and dispatched correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any ancillary data entry not provided by an electronic chain of custody system.

Screening is the initial rapid assessment for drug presence. Although Screening is a cost-efficient method to eliminate drug use in most samples, a subsequent confirmation is required for court admissibility in case of a positive result. Any samples with a presumptive positive in Screening mandate a secondary validation.

For samples showing a presumptive positive during Screening, additional hair is extracted from the original specimen for the Extraction process. In this stage, substances are drawn from hair at considerably lower concentrations compared to other approaches (e.g., urine or oral fluid), which renders hair drug screening a complex method.

To verify any positive results from Screening, methods such as GC/MS, GC/MS/MS, or LC/MS/MS are employed. Samples with presumptive positives are washed prior to confirmation as required. The complete lab process from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designations and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests have the ability to trace drug use for up to 90 days, unlike urine tests which offer a shorter perspective.
• Heightened security against tampering: Cheating a hair drug test is highly challenging, enhancing result accuracy.
• Historical insights: Offers a timeline of substance use patterns across a span, not merely recent consumption.

Limitations:

• Cannot detect immediate use: A period of approximately 5-7 days is required for drugs to be traceable in hair.
• Expense: Generally, hair drug tests incur greater costs than other testing approaches.
• Result variability: Factors such as hair pigmentation and personal differences in hair growth can influence drug metabolite concentrations in hair.

Note: Although frequently labeled as "hair follicle tests", the procedure analyzes the hair strand rather than the follicle below the scalp.

Why Hair Follicle Testing Beats Urine Testing

In White Lake, NC, hair follicle testing presents clear benefits over traditional urine testing. Superior detection accuracy is a key advantage, as hair testing captures a more extensive drug use history, providing a complete picture of an individual's habits.
