Hair Follicle Drug Testing - Mccaskill, AR

What it is, How it works

Hair testing is increasingly recognized as an effective method for determining drug and alcohol consumption. Hair captures a comprehensive timeline of alcohol and drugs by embedding biomarkers within the fibers of the growing strands. When obtained near the scalp, hair can reveal drug and alcohol use over a period of up to roughly three months. The collection process for hair is straightforward, relatively challenging to tamper with, and convenient for transportation.

A hair sample measuring 1.5 inches and including approximately 200 strands (comparable in thickness to a #2 pencil) nearest to the scalp should yield 100mg, which is the optimal amount for both screening and verification. For tests of EtG, add-ons, and/or beyond 10 panels, it is advised to collect 150mg of the specimen. It is suggested to measure the sample using a jeweler’s scale. If scalp hair is not accessible, a corresponding quantity of body hair can be collected. References to head hair specifically indicate scalp hair. Body hair encompasses all other types of hair (such as facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result consists of four main steps: Accessioning, Screening, Extraction, and Confirmation.

In the Accessioning step, the sample is initially processed into the laboratory’s system. This step involves ensuring that the sample was sealed and transported correctly, assigning it a random LAN (Laboratory Accessioning Number), and completing any necessary data entry not available via an electronic chain of custody system.

Screening serves as a preliminary rapid assessment for detecting drugs of abuse. While Screening is a cost-effective approach for dismissing drug use in most samples, a positive screen requires confirmation to be acceptable in legal proceedings. All samples that show a potential positive in Screening must undergo secondary confirmation.

For samples that yield a potential positive outcome during Screening, additional hair is extracted from the original sample and prepared for Extraction. During this phase, drugs are extracted from hair at a much lower concentration compared to other methods (like urine or oral fluid), which makes hair drug screening the most challenging method to execute.

Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed to be positive are washed before confirmation if required. The entire lab process from Accessioning to Confirmation is examined under the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection timeline: Hair drug screenings can identify drug use up to 90 days, unlike urine tests, which have a shorter detection duration.
• Difficulty in falsification: Tampering with a hair drug test is extremely challenging, which enhances the accuracy of results.
• Offers historical insights: It provides a depiction of drug usage patterns over time, rather than capturing only recent use.

Drawbacks:

• Does not detect recent use: Drugs generally become detectable in hair after about 5-7 days.
• Expense: Hair drug tests typically cost more than other drug testing techniques.
• Diverse results: Elements such as hair color and individual differences in hair growth can affect the concentration of drug metabolites in the hair.

Please note: Although commonly termed as "hair follicle tests," this test examines the hair strand itself, not the follicle beneath the scalp.
