Hair Follicle Drug Testing - Grasston, MN

What it is, How it works

The utilization of hair testing has emerged as an effective approach for identifying drug and alcohol misuse. Hair offers an extensive historical record of substance use by embedding biomarkers within the fibers of the active hair shaft. When gathered near the scalp, hair can furnish up to a roughly 90-day detection timeframe for alcohol and drugs. Collecting hair is straightforward, relatively tamper-resistant, and convenient for shipping.

An optimal sample consisting of a 1.5-inch segment of about 200 strands of hair (approximately the width of a #2 pencil) nearest to the scalp yields 100mg of hair, suitable for both screening and confirmation. For EtG testing, additional analyses, and/or assessments exceeding 10 panels, a sample of 150mg is advised. We suggest using a jeweler’s scale for specimen measurement. Should scalp hair be unavailable, a comparable quantity of body hair is acceptable. "Head hair" refers specifically to scalp hair, whereas "body hair" encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory procedure for processing a drug test result includes four key phases: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is initially processed into a laboratory’s system. This process involves confirming that the sample was securely sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any remaining data entry not covered by an electronic chain of custody system.

Screening consists of a preliminary quick assessment for substances of abuse. While Screening efficiently rules out drug use in most samples, a positive result necessitates confirmation to be valid in legal proceedings. Samples that test presumptively positive in Screening require additional verification.

When a sample yields a presumptively positive result during Screening, more hair is extracted from the primary specimen for Extraction. This process involves extracting drugs from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug screening methodologies.

Any positive screening outcomes are confirmed utilizing GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive specimens undergo washing before confirmation as required. The comprehensive laboratory process, from Accessioning to Confirmation, undergoes review adhering to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can identify drug consumption for up to 90 days, unlike urine tests with a shorter detection period.
• Limited potential for tampering: Hair drug tests are extremely challenging to manipulate, enhancing accuracy.
• Reveals usage patterns: Offers insights into drug use patterns over time, beyond recent usage.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair approximately 5-7 days post-consumption.
• Expense: Hair drug testing typically incurs higher costs than alternative drug testing methods.
• Variability in results: Hair color and individual differences in hair growth can influence the concentration of drug metabolites.

Note: Commonly referred to as "hair follicle tests," the analysis focuses on the hair strand itself and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

The advantages of hair follicle testing over urine analysis are clear in Grasston, MN. Hair tests provide more accurate and reliable results. Unlike traditional urine tests, a hair follicle test boasts a longer detection window, identifying substance use long after a urine test would fail. It leverages the inherent nature of hair growth, making it harder to manipulate, thus offering more genuine insights into a person's drug use history.

Extended Detection Window

Hair follicle testing in Grasston, MN brings about an extended detection period, capturing drug use over an impressive 90-day timeline. This allows employers a more comprehensive look into the substance histories of applicants or staff. Unlike other test types, hair testing doesn't just give a snapshot of recent activity, but a broader view, which is invaluable for maintaining long-term safety in the workplace.

Tamper-Resistant Testing Method

For those requiring trustworthy drug tests in Grasston, MN, hair follicle methods severely lower the chances of tampering. The test procedure intrinsically deters adulteration, ensuring the results are reliable and beyond dispute.
