Hair Follicle Drug Testing - Zenith, WA

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair secures a prolonged record of alcohol and drug intake by embedding biomarkers within its growing strands. When obtained near the scalp, hair can reveal substance usage within an approximate three-month timeframe. Collecting hair is straightforward, challenging to alter, and convenient to transport.

A sample measuring 1.5 inches, consisting of roughly 200 hair strands (approximately the diameter of a #2 pencil) nearest the scalp, yields 100mg of hair, which is the preferred amount for both screening and confirmation tests. For EtG, additional tests, and/or panels exceeding ten, it is advisable to gather 150mg of hair. It is recommended to measure the sample using a jeweler’s scale. Should scalp hair be unavailable, a similar quantity of body hair may be utilized. When mentioning head hair, it specifically means scalp hair, while body hair covers all other types (facial, axillary, etc.).

Process Overview

The four principal phases in processing a lab drug test are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase where a sample is introduced into a lab’s system. This step ensures the sample was correctly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data input not covered by an electronic chain of custody system.

Screening serves as an initial assessment for drug presence. Although Screening is a budget-friendly means to eliminate drug usage in most samples, a positive screen warrants confirmation for legal acceptance. Samples showing presumptive positives during Screening necessitate a subsequent confirmation.

When a sample tests presumptively positive during Screening, additional hair is retrieved from the original specimen for the Extraction process. This phase involves extracting drugs from hair at a lower concentration compared to other methods (e.g., urine or oral fluid), rendering hair drug analysis the most intricate methodology.

Positive results from the Screening process undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are washed before confirmation as deemed necessary. The comprehensive lab procedure from Accessioning to Confirmation is reviewed in compliance with both the CAP (College of American Pathologists) Hair designation and accreditation according to ISO / IEC 17025 standards.

Benefits of hair drug examination:

• Extended detection period: Hair drug assessments can identify drug usage for up to 90 days, unlike urine tests with a brief detection window.
• Hard to falsify: Evading a hair drug test is notably difficult, enhancing result accuracy.
• Offers historical insights: It provides a record of drug consumption trends over time, rather than just recent use.

Drawbacks:

• Inability to detect recent consumption: It takes about 5-7 days for substances to become detectable in hair.
• Expense: Hair drug evaluations are generally costlier than other drug testing approaches.
• Result variability: Aspects like hair color and individual hair growth differences can impact metabolite concentration in the hair.

Note: Commonly termed as "hair follicle tests", the assessment actually examines the hair strand, not the follicle beneath the scalp.
