Hair Follicle Drug Testing - North Omak, WA

What it is, How it works

Hair analysis is now recognized as an effective method for uncovering drug and alcohol consumption. It offers a prolonged record of substance use by capturing biomarkers within the fibers of the developing hair shaft. When harvested near the scalp, hair can indicate substance use over a span of up to three months. Collecting hair is straightforward, relatively tamper-proof, and easy to transport.

A hair sample of 1.5 inches comprising about 200 hairs (roughly the size of a number two pencil) near the scalp will yield 100mg, which is the optimal sample size for both screening and verification. For EtG, additional tests, and/or panels exceeding ten, 150mg of the sample is advised. It's recommended to measure the sample on a jeweler’s scale. If scalp hair is not available, a comparable quantity of body hair may be used. References to head hair specifically denote scalp hair. Body hair encompasses all other hair types (like facial and axillary hair).

Process Overview

The laboratory process for determining drug test outcomes comprises four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the primary integration of a sample into a lab’s framework. This involves confirming that the sample was correctly sealed and dispatched, assigning a LAN (Laboratory Accessioning Number), and completing any supplementary data input absent from an electronic chain of custody system.

Screening entails a preliminary evaluation for substance misuse. Although Screening is an economical approach to exclude drug presence in most samples, a positive finding must be confirmed to be valid in legal settings. Samples that test presumptively positive in Screening necessitate further validation.

If a sample tests presumptive positive during the Screening phase, additional hair is retrieved from the remaining sample and readied for Extraction. In this phase, substances are withdrawn from hair at a considerably reduced concentration compared to other methods (e.g., urine or oral fluid), underscoring why hair drug testing is the most intricate technique.

All positive results from screening undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before confirmation, every presumptively positive sample is cleaned if required. The entire laboratory process from Accessioning through Confirmation is scrutinized according to both CAP (College of American Pathologists) Hair accreditation and ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug consumption up to 90 days prior, unlike urine tests which offer a reduced detection window.
• Challenge to circumvent: It is extremely challenging to manipulate a hair drug test, enhancing the credibility of results.
• Yields historical insight: It narrates a chronicle of drug intake over a duration, not just recent use.

Limitations:

• Incapable of recent detection: It requires around 5-7 days for substances to become traceable in hair.
• Expense: Hair drug tests generally bear a higher cost than alternative testing procedures.
• Disparities in outcomes: Elements such as hair pigmentation and individual hair growth rates can influence drug metabolite levels in the hair.

Note: Frequently termed "hair follicle tests", they analyze the hair shaft rather than the follicle beneath the scalp.
