Hair Follicle Drug Testing - Roy, LA

What it is, How it works

Hair testing has become recognized as an influential method for identifying drug and alcohol consumption. Hair offers a prolonged timeline of substance use by capturing biomarkers within the strands as hair grows. When retrieved near the scalp, hair can provide up to about a 3-month observation period for both alcohol and drugs. It’s easy to collect, challenging to tamper with, and simple to transport.

A 1.5-inch piece consisting of around 200 hair strands (roughly the size of a #2 pencil) nearest to the scalp will provide 100mg of hair, regarded as the ideal amount for both screening and verification. For EtG, additional tests, and/or screens exceeding 10 panels, 150mg of the sample is advisable. Using a jeweler’s scale is recommended for weighing the specimen. In cases where scalp hair isn’t available, an equivalent quantity of body hair may be used. "Head hair" refers specifically to hair on the scalp, while "body hair" applies to other types of hair (such as facial and axillary).

Process Overview

The laboratory processing of a drug test result consists mainly of four steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning starts with the sample's initial integration into the lab's framework. This step ensures that the sample was appropriately sealed and sent, assigns a unique LAN (Laboratory Accessioning Number), and completes any supplementary data entry not handled by an electronic custody system.

Screening serves as an initial, rapid assessment for substance abuse. While this step is cost-efficient for excluding drug usage in most samples, a positive result needs confirmation for legal admissibility. Samples showing potential positivity in Screening must go through a subsequent confirmation.

If a sample tests potentially positive during the Screening phase, additional hair is taken from the original sample for further processing in the Extraction phase. Here, drug substances are separated from the hair at a significantly lower concentration than other methods (e.g., urine or oral fluid), which is why hair drug screening is deemed the most complex methodology to execute.

Verification of any positive result from Screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples that appear positive are cleansed before confirmation as necessary. The whole laboratory method from Accessioning through Confirmation is scrutinized under both CAP (College of American Pathologists) Hair guidelines and certified to ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection period: Hair tests can identify drug use for as long as 90 days, unlike urine tests that have a shorter detection period.
• Difficult to manipulate: Tampering with a hair drug test is highly challenging, ensuring the results are more reliable.
• Historical insight: This testing can reveal a trend of substance usage over an extended duration, not just recent intake.

Limitations:

• Cannot determine recent usage: It takes around 5-7 days for substances to appear in hair.
• Expensive: Hair tests generally bear higher costs compared to other drug testing approaches.
• Result variations: Influences like hair color and personal differences in hair growth can alter drug metabolite levels in the hair.

Note: Although commonly called "hair follicle tests", the test examines the hair strand and not the follicle located under the skin
