Hair Follicle Drug Testing - Glenwood, WA

What it is, How it works

Hair analysis has emerged as an effective means for identifying substance and alcohol consumption. Hair captures a long-term record of these substances by embedding biomarkers within the strands as they grow. When collected near the scalp, hair can reveal up to an approximate 90-day period of alcohol and drug presence. Hair is easy to gather, hard to tamper with, and convenient to transport.

A hair sample measuring 1.5 inches consisting of about 200 strands (similar in size to a #2 pencil) nearest to the scalp will yield 100mg of hair, which is optimal for evaluation and confirmation. For EtG, additional tests, or panels beyond 10, a specimen of 150mg is advised. It's suggested to measure the specimen with a jeweler’s scale. If scalp hair isn't available, a comparable quantity of body hair can be used. By head hair, we mean only scalp hair, while body hair includes all other hair categories (facial, axillary, etc.).

Process Overview

The laboratory process for evaluating a drug test result entails four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the initial handling of a sample within a lab's framework. This involves ensuring the sample was properly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not covered by an electronic chain of custody system.

Screening is a preliminary rapid assessment for substance abuse. Although Screening offers a cost-savvy method for excluding drug use in most samples, a positive result must be confirmed to be court-acceptable. Samples that show presumptive positive results during Screening require further confirmation.

Upon a presumptive positive result in the Screening phase, additional hair is retrieved from the initial sample and prepped for Extraction. At this phase, substances are drawn out from hair at a significantly lower concentration than with other approaches (e.g., urine or saliva), underscoring why hair drug analysis is among the most challenging methodologies to execute.

Confirmation for any positive Screening result proceeds using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo washing before confirmation if necessary. The complete lab procedure from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use up to 90 days, unlike urine tests which have a shorter detection period.
• Difficult to falsify: It is exceedingly hard to falsify a hair drug test, thus enhancing result accuracy.
• Offers historical insight: It can show a timeline of substance use over months, not just recent usage.

Limitations:

• Inability to detect immediate use: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Hair drug testing tends to be pricier than alternative drug testing methods.
• Result variability: Elements like hair color and individual differences in hair growth can influence the concentration of drug indicators in hair.

Note: Although commonly referenced as "hair follicle tests," the analysis actually examines the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why does hair follicle testing outshine urine testing in Glenwood, WA? Hair testing offers a broader detection scope, identifying substance use up to 90 days prior. Unlike urine tests, which capture only recent usage, hair tests ensure comprehensive insight into an individual's behavior, marking it superior in reliability and thoroughness.

The accuracy of hair testing mitigates false negatives and inconsistencies seen in traditional urine methods. Opting for hair follicle evaluations offers a more dependable means to uphold drug-free environments.

Extended Detection Window

Hair follicle testing's strength in Glenwood, WA, lies in its extended detection period, stretching up to 90 days. This longevity provides a clearer picture of an individual's substance use across months, rather than days, allowing employers to assess historical behavior effectively.

Employers benefit from this extensive window, acquiring detailed insights into a potential or current employee's substance history, assisting in educated decision-making for a safer work environment.

Tamper-Resistant Testing Method

Hair follicle tests in Glenwood, WA, present a robust guard against sample tampering. The difficulty in adulterating a hair sample ensures the results are authentic and credible, providing users with substantial confidence in the findings.

Particles remain embedded in hair strands, resisting external tampering techniques that may otherwise jeopardize results. Thus, hair testing provides an unquestionable, tamper-resistant methodology for drug evaluation.
