Hair Follicle Drug Testing - Little Canada, MN

What it is, How it works

Hair testing is recognized as a robust method for identifying drug and alcohol consumption. This method captures a long-term record of substances by embedding biomarkers in the strands of hair as they grow. When gathered near the scalp, hair can indicate alcohol and drug use over a period extending up to three months. It's easy to collect, somewhat resistant to tampering, and simple to transport.

A 1.5-inch segment consisting of roughly 200 hairs (comparable in size to a #2 pencil) from close to the scalp offers 100mg, the preferred amount for preliminary screening and further analysis. For examinations like EtG, additional tests, or those beyond 10 panels, 150mg of hair is suggested. It's advisable to measure the sample using a jeweler's scale. Should scalp hair be unavailable, an equivalent volume of body hair is acceptable. References to head hair are specific to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The primary stages in laboratory processing of a drug test are Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial entry of a sample into a lab's workflow. This step includes confirming the sample's secure sealing and shipment, as well as assigning a unique LAN (Laboratory Accessioning Number) and completing any missing data entry that an electronic custody system might not cover.

Screening provides a preliminary assessment for drug abuse. Although screening is a cost-efficient practice to negate drug use in most cases, a screen test showing positive must be confirmed to be legally valid. Presumptive positives from screening require an additional confirmation step.

When a screen indicates a presumptive positive, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are removed from hair at notably lower concentrations compared to other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug screening.

Positive results from screening are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives undergo washing before final confirmation if necessary. The complete lab procedure from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) guidelines for Hair designation and ISO/IEC 17025 certification standards.

Advantages of hair drug testing:

• Expanded detection period: Hair drug tests can show drug use over a 90-day timeframe, in contrast to urine tests which have a shorter span.
• Harder to falsify: Hair drug tests are difficult to manipulate, enhancing the reliability of results.
• Reveals drug use trends: It provides an overview of drug use patterns over time, not merely recent use.

Limitations:

• Unable to detect recent use: Drugs typically become detectable in hair after about 5-7 days.
• Expense: Hair drug tests tend to be pricier than other drug testing approaches.
• Result variability: Factors like hair color and individual hair growth rates can influence drug metabolite concentrations in hair.

Note: Although commonly termed "hair follicle tests", the assessment focuses on the hair strand itself rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Little Canada, MN, hair testing holds a significant advantage over traditional urine testing methods. Hair follicle tests are superior in detecting drugs with greater precision and reliability, owing to their longer detection window and less intrusive collection process.

Unlike urine tests, hair analysis can identify drug use over an extended period, diminishing the chances of recent abstinence masking substance use. It provides a clearer, long-term insight into drug habits, which is invaluable for comprehensive screenings.

Extended Detection Window

Hair follicle testing in Little Canada, MN, offers an extended detection window, making it ideal for understanding an individual's substance use history. It can detect drugs used up to 90 days prior, providing a much broader view than other testing methods.

Employers benefit from this extended timeline as it gives a more complete overview of an employee's drug use patterns, ensuring that they maintain a drug-free environment and make informed staffing decisions.

Tamper-Resistant Testing Method

In Little Canada, MN, hair follicle tests serve as a robust defense against sample tampering. Due to the nature of hair testing, attempts to alter or compromise the sample are significantly minimized, yielding trustworthy results.

The collection process involves a closely observed procedure that further ensures the integrity of the test, providing organizations with reliable data to base their critical decisions effectively, thus neutralizing any fraudulent attempts.
