Hair Follicle Drug Testing - Cedar Rock, NC

What it is, How it works

Hair analysis has emerged as a potent method for identifying drug and alcohol consumption. This technique offers an extensive history of substance use by capturing biomarkers within the hair's fibers as it grows. When hair is gathered close to the scalp, it can reveal substance use over a period of about three months. Hair is straightforward to collect, challenging to tamper with, and straightforward to transport.

Collecting a 1.5-inch segment of roughly 200 hair strands, similar in size to a #2 pencil, from near the scalp yields 100mg of hair, which is the optimal sample for testing and confirmation. For EtG, additional tests, and/or panels exceeding ten, 150mg of the sample is advised. Using a jeweler’s scale to weigh the specimen is suggested. If scalp hair cannot be accessed, an equivalent amount of body hair may be used. References to head hair imply only scalp hair, while body hair encompasses other types (facial, axillary, etc.).

Process Overview

The procedure for processing a drug test consists of Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the sample's initial incorporation into the laboratory’s system. This step involves confirming that the sample was properly sealed and dispatched, generating a random LAN (Laboratory Accessioning Number), and finalizing any outstanding data input not covered by an electronic chain of custody system.

Screening encompasses an initial rapid test for drug abuse. Screening offers a cost-efficient way to dismiss the possibility of drug use for most samples, yet positive results necessitate confirmation for legal admissibility. Any samples that test positive in Screening must be confirmed again.

In cases where the Screening result is presumptively positive, additional hair is taken from the original sample for Extraction. At this phase, drugs are extracted from hair at significantly lower levels than in other techniques (like urine or oral fluid), which makes hair drug screening the most complex methodology to execute.

Confirmation of any positive Screening is accomplished using GC/MS, GC/MS/MS, or LC/MS/MS. All positive samples are cleaned before confirmation as required. The complete laboratory process from Accessioning to Confirmation is inspected in compliance with both the CAP (College of American Pathologists) Hair designation and in line with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Protracted detection period: Hair drug tests can uncover drug usage for as long as 90 days, contrasting with urine tests that have shorter detection periods.
• Difficult to manipulate: Cheating a hair drug test is extremely challenging, thereby enhancing result accuracy.
• Offers longitudinal data: It provides a chronicle of drug consumption patterns over time rather than just recent usage.

Limitations:

• Cannot detect recent usage: It takes around 5-7 days for drugs to be noticeable in hair.
• Expense: Hair drug tests are typically costlier than alternative drug testing approaches.
• Result variability: Elements such as hair color and individual differences in hair growth can impact drug metabolite levels in hair.

Note: Although commonly termed as "hair follicle tests", the test actually examines the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing
