Hair Follicle Drug Testing - Hopkinsville, KY

What it is, How it works

The utilization of hair testing has been recognized as an effective method for identifying drug and alcohol consumption. Hair strands capture drug-related biomarkers within their fibers as they grow, providing an extended history of substance use. When hair is collected near the scalp, it can indicate drug and alcohol presence within an approximate 3-month timeframe. The collection process is straightforward, tampering is challenging, and transportation is uncomplicated.

A 1.5-inch segment consisting of roughly 200 strands (comparable to a #2 pencil) closest to the scalp will yield 100mg of hair, which serves as the optimal sample for both screening and confirmation processes. For EtG, additional examinations, and/or assessments involving more than 10 panels, 150mg of the sample is advisable. Utilizing a jeweler’s scale to weigh the specimen is recommended. Should scalp hair be unavailable, an equivalent quantity of body hair is an acceptable alternative. When discussing head hair, it specifically pertains to scalp hair, whereas body hair encompasses all additional hair types (such as facial or axillary hair).

Process Overview

The laboratory processing of drug test results consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is initially processed into the laboratory’s system. This step includes confirming the sample’s proper sealing and shipping, assigning it a unique LAN (Laboratory Accessioning Number), and completing any supplementary data entry not accounted for by an electronic chain of custody system.

Screening provides a preliminary evaluation for substance presence. It serves as an economical approach to discount drug use for most samples; however, a positive result in this stage necessitates confirmation for legal validity. Samples with presumptively positive results in Screening require further verification.

In cases where a sample tests positive in the Screening phase, additional hair is sourced from the original sample for Preparation in Extraction. This phase involves extracting drugs from hair, which occurs at comparatively lower concentrations than alternative methods (e.g., urine or oral fluid), hence the complexity of conducting hair drug screening.

Confirmation of any positive result from the Screening phase is carried out using GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Presumptive positive samples undergo washing before final confirmation when necessary. The entire lab procedure from Accessioning to Confirmation is meticulously reviewed according to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can monitor drug usage up to 90 days, unlike urine tests which cover shorter durations.
• Challenging to manipulate: Hair drug tests are highly resistant to manipulation, ensuring greater accuracy in the results.
• Delivers historical insights: This testing method can outline a pattern of drug usage over an extended timeframe, not merely recent consumption.

Limitations:

• Inability to identify recent use: It requires approximately 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests typically incur higher costs compared to other drug testing techniques.
• Result variability: Factors such as hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Although often labeled as "hair follicle tests", this test examines the hair strand itself, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing
