Hair Follicle Drug Testing - Greenbriar, VA

What it is, How it works

Hair analysis is recognized as a robust tool for uncovering drug and alcohol consumption. Hair can offer an extended history of substance use by encapsulating biomarkers within the fibers of the developing hair strand. When sampled near the scalp, hair can reveal substance use over about a 90-day period. The collection of hair is straightforward, challenging to tamper with, and convenient to transport.

A 1.5-inch segment of approximately 200 strands of hair (roughly the width of a #2 pencil) closest to the scalp yields 100mg, which is the optimal quantity for both screening and confirmation. For EtG, additional tests, and screenings beyond 10 panels, a collection of 150mg of the hair sample is advised. We suggest using a jeweler’s scale for accurate measurement. If scalp hair cannot be gathered, a similar amount of body hair can be utilized. The term head hair specifically denotes scalp hair, whereas body hair encompasses all other types (including facial, axillary, etc.).

Process Overview

The laboratory handling of a drug test involves four critical steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the initial inclusion of a sample into the lab's database. This step ensures that the sample is secured and dispatched correctly, assigns a unique LAN (Laboratory Accessioning Number), and incorporates any data entry not already covered by an electronic chain of custody protocol.

Screening entails an initial, rapid assessment for drug abuse. While Screening is a cost-efficient means to exclude drug usage for most samples, a positive screen must be validated for court purposes. Presumptive positives during Screening mandate a confirmatory follow-up.

For samples flagged as presumptively positive during the Screening phase, additional hair is extracted from the original specimen and made ready for Extraction. This process retrieves drugs from hair at significantly lower concentrations compared to other procedures (such as urine or oral fluid tests), making hair drug screening a notably complex method.

Confirmation of any positive screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS techniques. To assure accuracy, all samples marked as presumptive positives are cleansed before confirmation as needed. The full laboratory cycle from Accessioning to Confirmation is governed by the CAP (College of American Pathologists) Hair criteria as well as ISO / IEC 17025 accreditation standards.

Benefits of hair drug testing:

• Extended detection scope: Hair drug tests can track drug use for up to 90 days, unlike urine tests, which feature a more limited detection timeframe.
• Challenging to manipulate: Due to its nature, a hair drug test is difficult to deceive, ensuring the results are more precise.
• Reveals use patterns: It can illustrate a history of drug use over time, beyond just the recent activity.

Drawbacks:

• Delayed detection: It generally requires about 5-7 days for substances to become detectable in hair.
• Expense: Hair drug tests tend to cost more compared to alternative drug testing methods.
• Result variability: Drug metabolite concentrations in hair can be influenced by elements like hair color and individual hair growth differences.

Note: Although often called "hair follicle tests", this test actually examines the hair strand, not the follicle itself.

Why Hair Follicle Testing Beats Urine Testing

In Greenbriar, VA, hair follicle tests are more effective than urine tests for identifying long-term substance use. Unlike urine tests, which have limited detection windows, hair testing analyzes samples for drugs consumed over several months. This difference gives institutions reliant on drug-free policies an upper hand in vetting individuals. Additionally, hair tests are less susceptible to test manipulation.

Extended Detection Window

In Greenbriar, VA, hair testing's extended detection window reveals a broader spectrum of an individual's drug use history. Covering up to 90 days, this method provides employers with deeper insights into patterns and persistent substances, aiding informed decision-making. Such longevity in detection surpasses most traditional drug tests, making it invaluable for vigilant workplaces.

Tamper-Resistant Testing Method

Hair follicle testing in Greenbriar, VA, is renowned for its resistance to tampering. By closely analyzing hair samples, the method eradicates common adulteration tactics associated with other tests.
