Hair Follicle Drug Testing - Issaquah Plateau, WA

What it is, How it works

Hair analysis is now recognized as an effective method for detecting substance use, including drugs and alcohol. The hair captures biomarkers in its fibers, offering a long-term record of drug and alcohol intake. When cut near the scalp, hair can reveal drug and alcohol use over a period of up to three months. Collecting hair is straightforward, relatively tamper-proof, and easily transported.

A 1.5-inch segment comprising roughly 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp yields 100mg, which is perfect for both screening and confirmation. For EtG, additional tests, or panels exceeding ten, a sample weighing 150mg is suggested. It's advisable to measure the hair sample's weight using a jeweler's scale. Should scalp hair be absent, a similar quantity of body hair may be gathered. "Head hair" references scalp hair explicitly, whereas "body hair" denotes other types (e.g., facial, armpit hair).

Process Overview

The drug testing procedure in laboratories typically involves four critical stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes introducing the sample into the lab system. This step ensures the sample was appropriately sealed and transported, assigns it a unique LAN (Laboratory Accessioning Number), and completes any remaining data needs not covered by an electronic chain of custody.

Screening is a preliminary assessment to check for drug use. Although Screening is an economical way to negate drug use in most samples, a positive screening outcome mandates confirmation to be legally valid. Therefore, results indicating possible drug use in Screening require a further confirmatory test.

When Screening suggests potential drug presence, additional hair is extracted from the original sample for the Extraction phase. During Extraction, drugs are isolated from the hair at significantly lower concentrations than other methods (like urine or oral fluids), underscoring the challenges of hair drug analysis.

Verification of any positive screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS methods. Samples with presumed positivity are washed before verification as necessary. The comprehensive lab process from Accessioning to Confirmation complies with the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which offer a shorter detection span.
• Challenge to deceive: Cheating a hair drug test is exceedingly challenging, enhancing result accuracy.
• Historic usage insights: Hair testing reveals patterns of drug consumption over time, not merely recent usage.

Limitations:

• Delayed detection of recent use: Drugs become noticeable in hair roughly 5-7 days post-use.
• Higher cost: Hair drug testing typically incurs greater expenses than alternative testing techniques.
• Result variability: Elements such as hair color and growth differences can influence drug metabolite concentrations.

Note: Despite the nickname "hair follicle tests", this test examines the hair strand rather than the follicle beneath the skin.

Why Hair Follicle Testing Beats Urine Testing

When it comes to drug testing in Issaquah Plateau, WA, hair follicle tests outshine urine tests in several ways. Hair testing offers superior detection accuracy and reliability, capable of identifying a broader range of substances over extended periods.
