Hair Follicle Drug Testing - Dranesville, VA

What it is, How it works

Hair analysis is regarded as a potent method for identifying drug and alcohol consumption. By embedding biomarkers in the hair strand's fibers as it grows, hair retains a long-term record of alcohol and drug use. When sourced near the scalp, hair can reveal alcohol and drug use with a detection timeframe of almost three months. Hair is straightforward to gather, not easily tampered with, and simple to transport.

A sample measuring 1.5 inches comprising roughly 200 hair strands (approximately the width of a #2 pencil) adjacent to the scalp provides 100mg of hair, which is the optimal amount for both screening and confirmation. For extended tests such as EtG, add-ons, and panels exceeding 10, a 150mg sample is advisable. Checking the specimen weight on a jeweler’s scale is suggested. If scalp hair isn't available, an equivalent quantity of body hair is acceptable. Head hair specifically refers to scalp hair, while body hair includes all other hair categories (facial, axillary, etc.).

Process Overview

The lab procedures for processing a drug test entail four essential phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the outset of integrating a sample into a lab's system. This phase encompasses verifying the correct sealing and shipment of the sample, assigning it a unique LAN (Laboratory Accessioning Number), and supplementing any missing information not provided by an electronic custody system.

Screening provides an initial rapid assessment for drug abuse. Although Screening is economical for eliminating drug use across most samples, a court-admissible positive screen must undergo confirmation. Samples that show presumptive positivity in Screening require additional confirmation.

For samples flagged as presumptive positives during Screening, additional hair is extracted from the original sample and prepped for Extraction. At this step, drug extraction from hair occurs at a notably lower concentration compared to other methods (e.g., urine or oral fluid), which makes hair drug screening the most intricate methodology.

For any positive findings from Screening, Confirmation is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Any samples showing presumptive positivity are washed before confirmation if required. The comprehensive laboratory process, from Accessioning to Confirmation, complies with both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extensive detection window: Hair drug tests can identify drug usage for a duration extending up to 90 days, as opposed to urine tests which have a shorter detection range.
• Hard to manipulate: Cheating a hair drug test is exceedingly arduous, thus enhancing result precision.
• Chronicles past usage: Offers a pattern of drug consumption over time, instead of recent usage alone.

Limitations:

• Recent usage undetectable: It requires about 5-7 days before drugs become detectable in hair.
• Expense: Hair drug tests are typically pricier than other drug testing techniques.
• Result variability: Factors like hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Although commonly termed as "hair follicle tests", the actual test analyzes the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Dranesville, VA, hair follicle testing triumphs over traditional urine tests, offering greater detection accuracy and reliability.
