Hair Follicle Drug Testing - Silver Firs, WA

What it is, How it works

Recognized as a significant resource, hair testing effectively detects drug and alcohol usage. Hair fibers trap biomarkers as they grow, offering a prolonged history of alcohol and drug exposure. A sample taken near the scalp can potentially reveal substance use within a three-month detection period. Collecting hair is straightforward, challenging to tamper with, and easy to transport.

Obtaining a 1.5-inch length of approximately 200 hair strands (equivalent to a #2 pencil's thickness) nearest to the scalp yields about 100mg of hair, which is ideal for both screening and verification. For tests involving EtG, additional screenings, or those exceeding 10 panels, a 150mg sample is advised. It's advisable to weigh the specimen using a jeweler's scale. Should scalp hair be unavailable, an equivalent amount of body hair can be collected. "Head hair" specifically denotes scalp hair. "Body hair" encompasses all other hair types (such as facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four crucial stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage where a sample is entered into a lab's system. This process ensures the sample's secure sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and completes any necessary extra data entry not handled by an electronic chain of custody system.

Screening offers an initial rapid assessment for drug abuse. Although it provides a cost-effective approach to eliminating drug use in most samples, a positive result requires confirmation to hold validity in legal proceedings. Samples suspected of positivity in Screening require subsequent confirmation.

If Screening reveals a presumptive positive result, additional hair is drawn from the initial sample for Extraction. At this stage, drug content is extracted from hair at considerably lower concentrations compared to other methods (such as urine or oral fluid), making hair drug screening a sophisticated technique.

Positive Screening outcomes are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Any samples with presumptive positive results undergo washing before confirmation as necessary. The comprehensive lab process, ranging from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can expose drug usage for as long as 90 days, unlike urine tests which have a reduced detection span.
• Challenging to manipulate: Cheating a hair drug test poses significant difficulty, enhancing result accuracy.
• Historical usage data: Provides insight into drug usage patterns over an extended time, not merely recent activity.

Limitations:

• Incapacity to discern recent use: Detectable drug presence takes around 5-7 days to manifest in hair.
• Expense: Hair drug tests usually bear a higher cost than other testing modalities.
• Result disparities: Variables like hair color and personal hair growth differences can influence drug metabolite levels in the hair.

Note: Despite the common term "hair follicle tests," the actual analysis pertains to the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why do hair follicle tests outshine urine tests in Silver Firs, WA? The enhanced detection ability of hair tests is key.
