Hair Follicle Drug Testing - Wright, MN

What it is, How it works

Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair retains a comprehensive record of substance use by embedding biomarkers within the shafts of the emerging hair. When sampled near the scalp, hair can indicate drug and alcohol consumption for an approximate duration of three months. Collection is straightforward, tampering is challenging, and transport is uncomplicated.

Gathering a 1.5-inch segment, equivalent to around 200 hair strands (approximately the thickness of a #2 pencil) near the scalp yields 100mg of hair, which is ideal for both screening and confirmation processes. For EtG tests, additional panels, and assessments beyond 10 panels, a 150mg sample is preferred. It is advisable to weigh the sample using a jeweler's scale. If scalp hair is inaccessible, a comparable quantity of body hair may be used. References to head hair specifically denote scalp hair. Body hair encompasses other types like facial or axillary hair.

Process Overview

The laboratory assessment of drug test outcomes consists of four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary handling of a sample within a lab's framework. This phase includes ensuring the sample's proper sealing and dispatch, assigning a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data input absent from an electronic custody chain system.

Screening involves a swift preliminary detection of substance abuse. While Screening is cost-efficient in excluding drug use in most samples, positive screenings necessitate confirmation for legal admissibility. Any samples that yield presumptive positives in Screening mandate additional confirmation.

Should a sample yield a presumptive positive during the Screening phase, additional hair is retrieved from the original sample for further Extraction. In this phase, drugs are isolated from the hair at significantly reduced concentrations compared to other techniques (such as urine or saliva), making hair drug screening notably challenging to execute.

Confirmation of any positive screening outcome occurs using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo a wash before confirmation if necessary. The entire processing sequence, from Accessioning to Confirmation, adheres to CAP (College of American Pathologists) Hair standards and ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Prolonged detection period: Hair tests identify drug use for up to 90 days, whereas urine tests possess a more limited detection scope.
• Challenging to falsify: Hair tests are notably difficult to manipulate, ensuring more reliable results.
• Historical usage patterns: Provides insights into consistent drug use over time, not merely recent consumption.

Limitations:

• Inability to identify recent use: Drugs become detectable in hair approximately 5-7 days post-consumption.
• Expense: Generally more costly than alternative drug testing methods.
• Result variability: Factors such as hair pigmentation and personal hair growth rates can influence drug metabolite levels in the hair.

Note: Although often labeled as "hair follicle tests", the actual analysis centers on the hair shaft instead of the follicle beneath the skin.

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle tests to traditional urine tests in Wright, MN, hair testing demonstrates superior detection accuracy and reliability. Hair tests have an edge over urine tests due to their extended detection window. While urine tests provide information about recent drug use, hair tests offer a detailed history, making it a valuable tool for comprehensive drug policy enforcement.

Extended Detection Window

Hair follicle testing in Wright, MN, provides a window into an individual's substance use over an extended period, up to 90 days. This broad detection span gives employers insight into a person’s substance history, going well beyond the couple of days typical of other testing methods. This makes it invaluable for assessing long-term patterns of behavior and enhancing decision-making processes.

Tamper-Resistant Testing Method

In Wright, MN, hair follicle testing significantly reduces the possibility of adulteration, ensuring reliable and unquestionable results. Unlike other methods, which are susceptible to tampering, hair testing can't be easily altered once the sample is collected. This tamper-resistant nature provides an extra layer of assurance for both employers and agencies seeking honest results.
