Hair Follicle Drug Testing - Hollis, AK

What it is, How it works

Viewing hair testing as a robust resource for detecting substance use, it effectively captures a prolonged history of drug and alcohol consumption by encapsulating related markers in the hair fiber during its growth. If collected near the scalp, hair can potentially offer a detection timeline of up to roughly three months for substances. The collection process is straightforward, somewhat resistant to tampering, and convenient for transport.

A segment of 1.5 inches comprising roughly 200 hair strands (comparable in size to a #2 pencil) nearest to the scalp will yield 100mg of hair, deemed the optimal sample for both screening and confirmation processes. For EtG testing, additional services, and/or assessments exceeding 10 panels, it is suggestible to gather 150mg of the sample. Utilizing a jeweler’s scale for measurement is recommended. In cases where scalp hair is unavailable, a comparable amount of body hair may be obtained. When referring to head hair, it strictly means scalp hair. Body hair encompasses various other types of hair (facial, axillary, etc.).

Process Overview

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

Accessioning describes the preliminary sample processing within a laboratory's system. This stage includes ensuring the proper sealing and transport of the sample, assigning a random LAN (Laboratory Accessioning Number), and finalizing any additional data input absent from an electronic chain of custody protocol.

The Screening phase serves as an initial assessment for substance abuse. It offers a budget-friendly approach to discrediting drug usage among the majority of collected samples, albeit, a positive outcome necessitates confirmation to ensure its legal validity. Every sample that exhibits a presumptively positive result in Screening must undergo subsequent confirmation.

In instances of a presumptively positive outcome during Screening, additional hair is extracted from the original sample, readying it for the Extraction phase. During this phase, substances are extracted from hair at significantly reduced concentrations compared to other methods (e.g., urine or oral fluid), underscoring the complexity of performing hair drug screening.

The Confirmation of any positive result from screening employs techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples deemed presumptively positive undergo requisite washing prior to confirmation. The complete laboratory sequence from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug tests can trace drug use over a timeframe of up to 90 days, unlike urine tests which have a shorter detection range.
• Difficult to manipulate: The difficulty in falsifying a hair drug test lends greater credibility to the results.
• Reveals historical usage patterns: Offers insight into an individual's substance use over time, rather than only recent activity.

Limitations:

• Incapable of detecting recent consumption: It requires about 5-7 days for substances to become detectable in hair.
• Expense: Hair drug tests generally entail a higher cost compared to alternative drug testing approaches.
• Result variability: Differences such as hair color and personal hair growth rates can impact the drug metabolite concentrations present in the hair.

Note: Although frequently labeled as "hair follicle tests," the procedure examines the hair strand itself rather than the underlying scalp follicle.
