Hair Follicle Drug Testing - Pleasant Hill, OR

What it is, How it works

Hair analysis has emerged as an effective means for identifying drug and alcohol consumption. Hair captures a prolonged timeline of alcohol and substance use by embedding biomarkers within the strands as they grow. When collected near the scalp, it offers an approximate 3-month detection period for alcohol and substances. Hair collection is straightforward, challenging to manipulate, and convenient to transport.

An ideal sample consists of a 1.5-inch segment containing about 200 hairs (akin to the thickness of a #2 pencil) nearest to the scalp, equating to 100mg, perfect for both screening and confirmation. For EtG, additional tests, and/or more than 10-panel tests, a sample of 150mg is suggested. It is advisable to weigh the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair can be gathered. Reference to head hair denotes exclusively scalp hair, while body hair encompasses all other hair categories (facial, axillary, etc.).

Process Overview

The key phases in processing a lab drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning initiates the introduction of a sample into the lab system. This step verifies the sample's secure sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and completes any supplementary data entry absent in an electronic chain of custody system.

Screening is an initial swift evaluation for substance abuse. While Screening is cost-effective for negating drug use in most samples, a court-admissible positive result requires confirmation. Samples showing presumptive positivity in Screening necessitate a further confirmation test.

For samples testing presumptive positive at the Screening phase, more hair is extracted from the initial specimen to prepare for Extraction. Here, drugs are retrieved from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), rendering hair drug screening the most intricate technique to execute.

Positive screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples are thoroughly washed as required. The comprehensive lab process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use for up to 90 days, surpassing the shorter detection period of urine tests.
• Hard to falsify: Tampering with hair drug tests is notably challenging, ensuring higher result accuracy.
• Chronological drug use data: Provides insights into drug use patterns over a substantial timeframe, not merely recent usage.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair after roughly 5-7 days.
• Expense: Hair drug tests usually incur higher costs than alternative testing methods.
• Result variability: Attributes such as hair color and unique hair growth variations can impact the concentration of drug metabolites within hair.

Note: The term "hair follicle tests" is a misnomer, as the assessment targets the hair strand rather than the follicle beneath the scalp.
