Hair Follicle Drug Testing - Dawson, MD

What it is, How it works

Hair analysis is recognized as an effective method for identifying substance and alcohol consumption. The hair strand captures biomarkers within its fibers, offering a prolonged timeline of alcohol and drug usage. Collecting hair close to the scalp allows for a detection period of up to three months for alcohol and drugs. It's straightforward to collect hair, challenging to tamper with, and simple to transport.

Securing a 1.5-inch segment of approximately 200 hair strands near the scalp yields 100mg, which is the recommended sample size for testing and validation. For EtG, supplementary screenings, and tests that exceed 10 panels, 150mg is advised. It's best to use a jeweler’s scale for measuring the sample. If scalp hair isn't available, an equivalent quantity of body hair is acceptable. When mentioning head hair, we refer solely to scalp hair. All other hair types, such as facial and axillary, are classified as body hair.

Process Overview

The laboratory processing of a drug test outcome incorporates four key phases: Accessioning, Screening, Extraction, and Confirmation.

The Accessioning step includes the initial handling of a specimen into the lab’s system, ensuring the sample was properly sealed, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry needed that isn't covered by an electronic chain of custody system.

Screening entails an initial rapid assessment for substances. Though cost-effective in eliminating drug use in most samples, a positive screen requires confirmation for court admissibility. Any samples that appear positive during Screening need further confirmation.

If a sample appears positive during Screening, additional hair is taken from the original sample for Extraction. This step involves extracting drugs from the hair, albeit at lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening a complex methodology.

Positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation if required. The entire lab process from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection window: Can identify drug use for up to 90 days, unlike the shorter detection period of urine tests.
• Difficulty to cheat: Cheating a hair drug test is highly challenging, enhancing accuracy.
• Provides historical data: Offers a pattern of substance use over time, not just recent usage.

Limitations:

• Cannot detect recent use: Drugs generally become apparent in hair after 5-7 days.
• Cost: Hair drug testing tends to be more costly than other testing methods.
• Variations in results: Factors such as hair color and individual hair growth variations can impact drug metabolite concentration in hair.

Note: Often termed "hair follicle tests", the actual analysis focuses on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Dawson, MD, hair follicle testing surpasses traditional urine tests, offering several advantages. The enhanced detection fidelity of hair tests captures drug use over an extended timeframe of up to 90 days, providing more reliable data for evaluators. Meanwhile, urine tests, though useful for recent usage detection, fall short of offering such a comprehensive history.

Employers in Dawson seeking robust drug detection methods find hair testing superior due to its accuracy. Unlike urine tests, the meticulous analysis of hair samples diminishes the chances of false positives, ensuring precise identification of substance use.

Extended Detection Window

Hair follicle drug testing provides an extended detection window, up to 90 days, significantly longer than other testing methods available in Dawson, MD. This extensive timeframe gives employers a better understanding of an individual's drug use over months, rather than days, leading to more informed decisions.

With hair testing, employers can comprehensively evaluate an applicant or employee’s substance history. This method aids in maintaining a safe and drug-free workplace by offering insights into long-term drug use patterns that shorter windows cannot detect.
