Hair Follicle Drug Testing - Mount Tabor, VT

What it is, How it works

Hair testing is recognized as an effective means for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug use by locking in biomarkers within the strands of the hair as it grows. When sourced close to the scalp, hair can reveal a detection timeline of up to roughly 3 months for alcohol and drugs. It is straightforward to collect, relatively challenging to tamper with, and simple to transport.

A 1.5-inch segment of about 200 hair strands (around the size of a #2 pencil) nearest the scalp will yield 100mg, which is considered the perfect sample size for preliminary screening and confirmation. For EtG, add-ons, and/or analyses exceeding 10 panels, it's advised to obtain 150mg. Using a jeweler’s scale to weigh the sample is suggested. If scalp hair isn't available, the equivalent volume of body hair can be used. 'Head hair' specifically denotes scalp hair while 'body hair' encompasses all other types (such as facial or axillary hair).

Process Overview

The primary stages in processing a lab drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial introduction of a sample into the lab's system. This stage verifies proper sealing and shipping of the sample, assigns a LAN (Laboratory Accessioning Number), and completes any additional electronic chain of custody system data that isn't automatically entered.

Screening performs a preliminary assessment for substance abuse. While Screening provides a cost-efficient method to eliminate drug usage in most samples, a confirmed positive is necessary for legal purposes. Each sample yielding a presumptively positive indication from Screening mandates a secondary confirmation.

In cases where Screening suggests a positive result, additional hair is extracted from the specimen and prepared for Extraction. During this phase, drugs are drawn out from hair at a significantly reduced concentration compared to other methodologies (e.g., urine or oral fluid), which accounts for hair drug testing being the most complex methodology to conduct.

GC/MS, GC/MS/MS, or LC/MS/MS methods are used for confirming any positive screening results. Prior to confirmation, all presumptively positive samples undergo a wash as needed. The entire lab process from Accessioning to Confirmation is examined under both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation criteria.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests can reveal drug usage for up to 90 days compared to urine tests, which have a shorter detection period.
• Hard to manipulate: Cheating a hair drug test is quite difficult, resulting in more precise outcomes.
• Supplies historical insight: It can exhibit patterns of drug usage over time, not just recent consumption.

Limitations:

• Inability to identify recent usage: Drugs require about 5-7 days to become detectable in hair.
• Expense: Hair drug testing generally incurs higher costs than alternative testing approaches.
• Result variation: Factors like hair color and individual hair growth rates can influence drug metabolite concentration in hair.

Note: Often called "hair follicle tests", the analysis actually examines the hair strand and not the follicle beneath the scalp.
