Hair Follicle Drug Testing - Hargill, TX

What it is, How it works

Hair testing has gained recognition as an effective means for identifying drug and alcohol consumption. Hair contains a prolonged record of alcohol and drug usage by encapsulating biomarkers within the fibers of the growing strand. When taken close to the scalp, hair delivers approximately a 3-month timeframe for detecting alcohol and drug presence. Collecting hair is straightforward, relatively resistant to tampering, and simple to transport.

A 1.5-inch segment of roughly 200 hair strands (comparable to the thickness of a #2 pencil) near the scalp provides 100mg, the preferred sample weight for analysis and validation. For EtG, additional tests, and/or panels exceeding 10, one should consider collecting 150mg of the sample. Utilizing a jeweler’s scale for specimen measurement is advisable. If scalp hair isn't available, an equivalent amount of body hair can be collected. When discussing head hair, we are specifically alluding to scalp hair. Body hair encompasses all other hair varieties (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test outcome comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the sample's initial processing into the laboratory’s system. This step includes confirming that the specimen was correctly sealed and transported, allotting a random LAN (Laboratory Accessioning Number), and finishing any further data entry absent an electronic chain of custody system.

Screening constitutes an introductory rapid assessment for illicit drugs. While Screening is a cost-effective approach to excluding drug use in most instances, a positive screen requires confirmation to be valid in judicial settings. Any samples that screen positively are subject to a secondary verification.

Incase a sample tests positively during the Screening, additional hair is extracted from the initial sample and prepped for Extraction. At this phase, drugs are taken from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), explaining why hair drug testing is notoriously intricate to conduct.

Any positive screening results undergo Confirmation through GC/MS, GC/MS/MS or LC/MS/MS. All positive samples undergo cleaning prior to necessary confirmation. The complete laboratory procedure from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 certification standards.

Advantages of hair drug testing:

• Long detection window: Hair drug assessments can track drug use for up to 90 days, unlike urine tests that feature a shorter detection interval.
• Difficulty to cheat: Cheating a hair drug test is remarkably challenging, resulting in more credible outcomes.
• Provides historical data: It portrays a pattern of drug usage over time, not just recent consumption.

Limitations:

• Cannot detect recent use: Drugs take about 5-7 days to become visible in hair tests.
• Cost: Hair drug tests tend to be pricier than other drug testing techniques.
• Variations in results: Elements like hair color and unique hair growth rates can impact the concentration of drug metabolites in hair.

Note: Though frequently labeled as "hair follicle tests", the test analyzes the hair strand rather than the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing
