Hair Follicle Drug Testing - Lake City, AR

What it is, How it works

Hair analysis has emerged as an effective approach for identifying drug and alcohol consumption. Hair captures a continuous record of alcohol and drug use by embedding biomarkers within the hair shaft's fibers. When collected near the scalp, hair can offer an approximate three-month detection period for alcohol and drugs. Hair is easy to gather, relatively resistant to tampering, and straightforward to transport.

A 1.5-inch segment of roughly 200 hair strands (comparable to a #2 pencil's thickness) nearest to the scalp will yield 100mg of hair, which is optimal for screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, a 150mg sample is advisable. Using a jeweler's scale for weighing the sample is suggested. In the absence of scalp hair, an equivalent quantity of body hair may be collected. When mentioning head hair, it exclusively refers to scalp hair. Body hair encompasses all other hair forms (facial, axillary, etc.).

Process Overview

The key phases in laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the sample's initial integration into the laboratory’s system. This phase includes ensuring the sample's proper sealing and transportation, assigning a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry absent from an electronic chain of custody process.

Screening constitutes an initial rapid check for abuse substances. Although cost-effective for negating drug use in most samples, a positive screen necessitates confirmation for court acceptability. Samples presumptively positive in Screening undergo secondary confirmation.

Should a sample test presumptively positive in Screening, additional hair is extracted from the primary specimen and prepped for Extraction. This phase involves extracting drugs from hair at lower concentrations than other methods (e.g., urine or oral fluid), which accounts for hair drug screening's complexity.

Positive screening outcomes are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned before confirmation as necessary. The complete laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use up to 90 days, contrasting with urine tests' shorter detection span.
• Hard to falsify: Cheating a hair drug test is extremely challenging, ensuring more reliable results.
• Supplies historical insights: It records a pattern of drug usage over time, beyond just recent activity.

Limitations:

• Does not identify recent usage: Drugs take around 5-7 days to become discernible in hair.
• Expense: Hair drug tests typically incur higher costs than other drug testing techniques.
• Result variability: Differences such as hair color and individual hair growth variations can influence drug metabolite concentrations in hair.

Note: Often termed "hair follicle tests," this test actually evaluates the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Lake City, AR, hair follicle testing has distinct advantages over traditional urine testing. One major benefit is its extended detection window, allowing for a much broader view of an individual's substance use. While urine tests often miss long-term drug use, hair testing accurately reflects a pattern of behavior.

Further, hair follicle tests offer superior accuracy in detecting a variety of substances. They remove any doubts regarding the reliability of the results, which is a significant concern with traditional methods. This makes hair testing an excellent choice for employers demanding stringent screening protocols.

Extended Detection Window

The extended detection range of hair follicle testing in Lake City, AR, provides a clear advantage by capturing evidence of drug use over as many as 90 days. This extensive window makes it invaluable for a deep dive into an employee's substance use history.

Employers appreciate the depth hair testing offers, as it helps them make informed decisions based on a comprehensive view of behavior rather than a snapshot. This comprehensive perspective aids in maintaining a high standard of workplace safety and reliability.

Tamper-Resistant Testing Method

In Lake City, AR, hair follicle tests are recognized for their resistance to tampering, ensuring the authenticity of results. The method of collection and testing significantly reduces the risk of adulteration, a common issue in other testing forms.
