Hair Follicle Drug Testing - Kamilche, WA

What it is, How it works

Hair analysis is increasingly recognized as a robust method for identifying drug and alcohol consumption. It retains a comprehensive record of substance use by embedding biomarkers within the growing hair shaft. When obtained near the scalp, hair can reveal substance usage for up to a three-month timeframe. It is easy to collect, presents challenges to adulterate, and is straightforward to transport.

Acquiring a 1.5-inch piece of roughly 200 hair strands, equivalent to the girth of a #2 pencil, near the scalp yields 100mg of hair, optimal for testing and verification. For EtG, additional assays, or tests exceeding 10 panels, a sample size of 150mg is suggested. It's advisable to measure the sample using a jeweler's scale. In the absence of scalp hair, a similar quantity of body hair can be taken. Reference to head hair pertains solely to scalp hair, while body hair encompasses all other hair varieties (e.g., facial, axillary).

Process Overview

The laboratory workflow for processing a drug test outcome consists of four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the procedure of integrating a sample into a lab's database. This step includes confirming the sample's proper sealing and shipment, allocating a unique LAN (Laboratory Accessioning Number), and filling in any further information absent from an electronic chain of custody system.

Screening is a preliminary, cost-efficient assessment for identifying illicit drug use. Although useful for excluding substances in most samples, any positive indication in Screening requires verification to be upheld in legal proceedings. Samples testing presumptively positive during Screening mandate secondary verification.

For samples presumed positive at Screening, additional hair is extracted from the original sample and readied for Extraction. This phase involves separating drugs from hair at markedly lower concentrations than in alternate techniques (such as urine or oral fluid), which is why hair drug screening is notably challenging to conduct.

Verification of any positive result from Screening is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before confirmation as necessary. The complete laboratory process, from Accessioning through Confirmation, is evaluated in line with both the CAP (College of American Pathologists) Hair criteria and the accreditation conforming to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection range: Hair drug analyses can pinpoint drug use for as long as 90 days, in contrast to urine tests with a narrower detection span.
• Hard to falsify: Hair drug tests are quite difficult to manipulate, enhancing the accuracy of the findings.
• Offers longitudinal data: These tests can chart a history of drug use over time, not merely recent consumption.

Limitations:

• Inability to detect recent use: Drugs typically take 5-7 days to become detectable in hair.
• Cost: Hair drug screenings tend to be pricier than other testing procedures.
• Result variability: Elements such as hair color and individual differences in hair growth can influence the concentration of drug metabolites in hair.

Note: Commonly termed "hair follicle tests", the tests evaluate the hair shaft itself, not the follicle beneath the scalp
