Hair Follicle Drug Testing - Covada, WA

What it is, How it works

Hair examinations have evolved to be acknowledged as an effective mechanism for recognizing substance and alcohol consumption. Hair captures a prolonged chronology of alcohol and drug intake as it seizes biomarkers within the strands of expanding hair fibers. When procured near the root, hair can offer approximately a 90-day window for detecting alcohol and other substances. Hair collection is straightforward, relatively resistant to tampering, and convenient for transport.

A 1.5-inch portion consisting of around 200 hair fibers (approximately matching a #2 pencil's thickness) nearest to the root yields 100mg of hair, which is the optimal sample for both screening and verification. For EtG tests, additional panels, and tests exceeding 10 panels, a 150mg sample is suggested. It is advisable to measure the sample’s weight using a jeweler's scale. If scalp hair is inaccessible, a comparable quantity of body hair can be obtained. When cited as head hair, it indicates exclusively scalp hair, whereas body hair encompasses all other types such as facial, axillary, etc.

Process Overview

The quartet of pivotal steps in the lab processing of a drug test result comprises Accessioning, Screening, Extraction, and Validation.

Accessioning pertains to the initial processing of a specimen into the lab's framework. It involves confirming the proper sealing and shipment of the sample, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any missing data entry that an electronic custody system does not provide.

Screening entails a preliminary swift evaluation for drugs of abuse. Although Screening is an economical method to exclude drug use for the majority of samples, a positive outcome necessitates confirmation to be court-admissible. Any samples with presumed positive results in Screening need subsequent confirmation.

Should a sample yield a presumptive positive result in the Screening phase, additional hair is extracted from the original sample for Preparation for Extraction. This stage involves isolating drugs from hair at a concentration considerably lower than that used in other methodologies (e.g., urine or oral fluid), which renders hair drug evaluation the most challenging technique to execute.

Validation of any positive screening results is accomplished through GC/MS, GC/MS/MS, or LC/MS/MS. All presumed positive samples undergo cleansing prior to validation as appropriate. The entire lab procedure from Accessioning to Validation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug evaluations can trace drug utilization for as much as 90 days, contrasted with urine tests which have a briefer detection range.
• Challenge in cheating: It is extremely challenging to deceive a hair drug evaluation, ensuring greater accuracy in results.
• Provides historical data: It can offer an overview of drug usage trends over time, beyond just recent usage.

Limitations:

• Inability to detect recent usage: It takes about 5-7 days for substances to become recognizable in hair.
• Expense: Hair drug evaluations generally incur higher costs compared to other testing methods.
• Variability in outcomes: Elements such as hair color and individual differences in growth rates can influence drug metabolite levels in hair.

Note: Although commonly referred to as "hair follicle tests", the evaluation itself targets the hair strand and not the follicle beneath the skin.

Why Hair Follicle Testing Beats Urine Testing

In Covada, WA, hair tests stand superior to urine alternatives, providing enhanced detection accuracy. Hair follicle testing yields a broader window of detection, revealing drug use up to 90 days back, while urine tests are limited in time frame.
