Hair Follicle Drug Testing - Mckenney, VA

What it is, How it works

The perception of hair testing as an effective instrument for identifying alcohol and substance use has gained traction. Hair captures a longitudinal record of alcohol and drug biomarkers within the fibers as the hair grows. When obtained close to the scalp, hair samples can exhibit detection capabilities for substances over approximately three months. Hair sample collection is straightforward, challenging to tamper with, and convenient for shipping.

Gathering a 1.5-inch segment of roughly 200 hair strands (similar to the diameter of a #2 pencil) near the scalp yields 100mg of hair, which is the ideal quantity for testing and verification. For EtG, extra screenings, or assays exceeding 10 panels, a minimum specimen of 150mg is advised. We suggest measuring the specimen with a jeweler’s scale. In the absence of scalp hair, a similar volume of body hair can be gathered. References to head hair indicate scalp hair only, while body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory process for drug test results encompasses four principal stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample undergoes initial processing within a laboratory’s framework. This procedure includes ensuring that the sample is securely sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any additional information entry not already available via an electronic chain of custody system.

Screening functions as a preliminary evaluation for drug presence. Although Screening is cost-effective, any positive findings require confirmation for legal admissibility. Samples that test presumptively positive in Screening must undergo a secondary validation process.

Should a sample test presumptively positive during Screening, extra hair will be collected from the original sample in preparation for Extraction. This stage involves extracting drugs from hair at notably lower concentrations than alternative methods (e.g., urine or oral fluid), underscoring the complexity of hair drug screening.

Affirmation of any positive screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples undergo washing if needed. The entire laboratory workflow from Accessioning to Confirmation is evaluated under both CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can identify drug use for up to 90 days, in contrast to urine tests with a shorter detection scope.
• Difficulty to cheat: Hair drug tests are notably hard to manipulate, resulting in more accurate outcomes.
• Provides historical data: Offers insights into drug consumption patterns over time, beyond recent usage.

Limitations:

• Cannot detect recent use: Typically, it takes around 5-7 days for drugs to become detectable in hair.
• Cost: Generally, hair drug tests carry higher costs compared to other testing methods.
• Variations in results: Factors like hair color and individual hair growth differences can impact drug metabolite levels in hair.

Note: Commonly termed "hair follicle tests", the procedure examines the hair strand rather than the actual follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing offers distinct advantages over urine tests, particularly in McKenney, VA. The most obvious benefit is the extended detection period, allowing for a more comprehensive understanding of an individual's drug use history. Unlike urine tests, hair analysis can detect substance consumption over months, providing a broader picture.

Furthermore, hair testing boasts superior accuracy. The structure of hair retains drug metabolites longer than urine, leading to more reliable results. This method also minimizes the potential for tampering, a common issue with urine tests, ensuring that results remain untainted and credible.

Extended Detection Window

In McKenney, VA, hair follicle tests excel with their extended detection period, analyzing drug use over a span of up to 90 days. This timeframe allows employers to gain comprehensive insights into an individual's substance history, greatly surpassing the capabilities of more traditional methods.

This broad detection window offered by hair testing provides a clearer picture of consistent substance use, deterring sporadic users from escaping notice. It offers employers a more thorough means of assessing the long-term habits of their applicants or employees, fostering a safer workplace environment.

Tamper-Resistant Testing Method
