Hair Follicle Drug Testing - Ira, VT

What it is, How it works

Hair analysis has emerged as a crucial method for identifying substance and alcohol intake. Hair offers an extensive history of alcohol and drug presence by capturing biomarkers within the fibers of the developing hair strand. When obtained near the scalp, hair can reveal a detection window for alcohol and substances of up to roughly three months. Hair is straightforward to collect, presents some challenges for tampering, and is convenient to transport.

A hair sample measuring 1.5 inches, consisting of approximately 200 strands (similar in size to a #2 pencil) proximate to the scalp, yields 100mg of hair, the optimal sample size for analysis and verification. For EtG, additional tests, and/or panels exceeding 10, a recommendation of 150mg of the specimen is suggested. Assessing the specimen's weight on a jeweler’s scale is advised. Should scalp hair be unavailable, a comparable quantity of body hair can be obtained. When we mention head hair, it pertains solely to scalp hair. Body hair encompasses all other hair forms (facial, axillary, etc.).

Process Overview

The lab procedure for processing a drug test outcome encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial entry of a sample into a lab’s framework. This process includes confirming the sample was appropriately sealed and sent, allocating a random LAN (Laboratory Accessioning Number), and finalizing any added data input absent from an electronic chain of custody system.

Screening offers a preliminary quick evaluation for substances of abuse. While Screening is an economical approach to exclude drug usage in most samples, a positive screen must be validated to hold up legally. Samples indicating a presumptive positive in Screening indeed necessitate follow-up confirmation.

Upon a presumptive positive outcome during the Screening phase, further hair is drawn from the initial sample and prepped for Extraction. In this phase, substances are drawn from hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), which renders hair drug analysis the most complex method to conduct.

Confirmation of any positive screening is achieved using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All preliminary positive samples undergo washing prior to confirmation as necessary. The complete lab sequence from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug evaluations can reveal substance usage up to 90 days, versus urine tests which have a more limited detection period.
• Fraud resistance: Cheating a hair drug test is notably challenging, enhancing result accuracy.
• Supplies historical insight: It provides a pattern of substance use across a span of time, not merely recent intake.

Limitations:

• Incapability to detect recent intake: Approximately 5-7 days are required for substances to become detectable in hair.
• Pricing: Hair drug tests tend to be pricier than alternative drug testing methods.
• Result variability: Elements such as hair color and personal differences in hair growth may influence drug metabolite concentration in the hair.

Note: While often termed as "hair follicle tests", the examination itself assesses the hair strand rather than the follicle beneath the scalp
