Hair Follicle Drug Testing - Stokes, NC

What it is, How it works

Hair analysis is now recognized as an effective means for identifying drug and alcohol consumption. Hair captures a chronological record of alcohol and drug intake by embedding biomarkers within the strands of growing hair. When collected near the scalp, hair can offer a detection timeframe of up to approximately 90 days for alcohol and drugs. Hair is easy to collect, challenging to tamper with, and convenient to transport.

A sample of 1.5 inches with about 200 hair strands (roughly the thickness of a #2 pencil) near the scalp will yield 100mg of hair, the optimal sample size for screening and verification. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the sample is advised. It is suggested to weigh the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair can be collected. References to head hair concern scalp hair solely. Body hair encompasses all other hair types (facial, underarm, etc.).

Process Overview

The drug testing process in the lab encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves incorporating a sample into a lab’s system. This step includes verifying the sample’s sealing and proper shipment, allocating a random LAN (Laboratory Accessioning Number), and concluding any additional data input not covered by an electronic chain of custody system.

Screening constitutes an initial swift assessment for drug abuse. While Screening is a cost-efficient method to negate drug usage in most samples, a positive result necessitates confirmation for it to be court-admissible. Samples showing preliminary positive results during Screening require subsequent confirmation.

If a sample returns a presumptive positive during Screening, additional hair is extracted from the initial sample for Extraction. During this phase, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which contributes to the complexity of hair drug analysis.

For any positive results in screening, confirmation is undertaken using GC/MS, GC/MS/MS, or LC/MS/MS. All samples thought to be positive undergo washing before confirmation as needed. The complete laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug usage for as long as 90 days, whereas urine tests detect for a shorter period.
• Tough to falsify: Cheating on a hair drug test is quite difficult, enhancing result accuracy.
• Shows usage patterns: It illustrates a timeline of drug use over time, not just recent activity.

Limitations:

• Cannot detect recent consumption: Drugs become detectable in hair within approximately 5-7 days.
• Expense: Hair drug tests are typically pricier than other drug testing techniques.
• Result variability: Factors like hair color and personal variations in hair growth can impact drug metabolite concentration in hair.

Note: While frequently dubbed “hair follicle tests”, the test examines the hair strand and not the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

Why is hair follicle testing preferred over traditional urine tests in Stokes, NC? The answer is simple: superior detection accuracy and reliability. While urine tests are conventional, hair testing provides more consistent and trustworthy data when monitoring substance misuse.
