Hair Follicle Drug Testing - Pleasant Hill, LA

What it is, How it works

Hair testing is recognized as an effective method for detecting drug and alcohol consumption. Hair offers an extended timeline of alcohol and drug use by encapsulating biomarkers within the fibers of the hair as it grows. When collected near the scalp, hair can reveal drug and alcohol use within approximately a 90-day period. It is easy to gather hair samples, challenging to tamper with them, and convenient to transport.

A 1.5-inch strand sample, approximately 200 hairs (around the thickness of a #2 pencil) near the scalp, provides 100mg of hair, which is the preferred quantity for testing and confirmation. For extensive tests, such as EtG add-ons or over 10 panels, 150mg of hair is suggested. Utilizing a jeweler’s scale for weighing the sample is advisable. If scalp hair isn't available, an equivalent amount of body hair may be used. References to head hair imply scalp hair only, while body hair encompasses all other types (such as facial and axillary hair).

Process Overview

The laboratory processing of a drug test result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of integrating a sample into the lab’s system. This step involves confirming the sample's proper sealing and shipment, assigning a random Laboratory Accessioning Number (LAN), and completing additional data entry not supplied by an electronic chain of custody system.

Screening offers a preliminary assessment for drug abuse. Although a cost-efficient means to eliminate drug use in most samples, any positive result at this stage requires confirmation to be legally valid. Presumptively positive samples in Screening need subsequent confirmation.

In cases of presumptive positivity during Screening, more hair is extracted from the primary specimen for Extraction. During this stage, drugs are isolated from hair at lower concentrations than other methods (like urine or oral fluid), which accounts for the complexity of performing hair drug screening.

Confirmation for any positive results obtained during screening is achieved using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples showing presumptive positivity are properly washed before confirmation if deemed necessary. The entire laboratory workflow from Accessioning to Confirmation is reviewed adhering to both CAP (College of American Pathologists) Hair guidelines and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug examinations can reveal drug use extending to 90 days, as opposed to urine tests, which have shorter detection timelines.
• Difficult to falsify: Cheating on a hair drug test is highly challenging, thereby ensuring more accurate outcomes.
• Delivers historical insights: It can demonstrate a trend of drug use over time, rather than just immediate consumption.

Limitations:

• Cannot reveal recent use: Drugs take roughly 5-7 days to manifest in hair samples.
• Expense: Hair drug examinations typically incur higher costs compared to other drug-testing methods.
• Result variability: Individual factors like hair color and growth rates may influence the drug metabolite levels present in hair.

Note: Although often referred to as "hair follicle tests," the analysis involves the hair strand rather than the follicle below the scalp.
