Hair Follicle Drug Testing - Burchard, MN

What it is, How it works

The use of hair testing has emerged as a significant method for uncovering drug and alcohol consumption. Hair captures a comprehensive timeline of substance use by embedding biomarkers within the strands as they grow. Collecting hair near the scalp provides a detection window for substances extending up to about three months. The collection process is straightforward, hair alteration is relatively challenging, and shipping is convenient.

An ideal sample involves a 1.5-inch segment of around 200 hair strands (roughly equivalent to the circumference of a #2 pencil) at the scalp, equating to 100mg. This is perfect for both screening and confirmation. For EtG add-ons or tests exceeding 10 panels, a 150mg sample is advised. Using a jeweler's scale for weighing the specimen is suggested. In cases where scalp hair is inaccessible, body hair equivalent in quantity can be used. When mentioning head hair, it exclusively pertains to scalp hair. Body hair includes all other types like facial, axillary, etc.

Process Overview

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

Accessioning is the preliminary stage where the sample is introduced into the lab system. This step ensures proper sealing and shipment of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any data entry not already present from an electronic chain of custody system.

Screening offers an initial rapid evaluation for drugs of abuse. Although cost-efficient for eliminating drug presence in most samples, a positive result from Screening requires confirmation to be court-admissible. Presumptive positives from Screening necessitate secondary confirmation.

For samples showing presumptive positives at the Screening stage, additional hair is extracted from the main sample and prepped for Extraction. Here, drugs are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug testing one of the most intricate methodologies.

Positive screenings are validated through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, any presumptive positive samples undergo washing if necessary. The entire lab process from Accessioning to Confirmation adheres to CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can track drug use for as long as 90 days, whereas urine tests have a more limited detection period.
• High resistance to contamination: Cheating a hair drug test is extremely difficult, ensuring more precise results.
• Tracing usage patterns: It reveals usage trends over time rather than just recent usage.

Limitations:

• Inability to detect recent use: It requires about 5-7 days before drugs become detectable in hair.
• Expense: Generally, hair drug tests cost more than other drug testing techniques.
• Result variability: Drug metabolite concentrations can differ due to factors such as hair color and growth variations.

Note: Although commonly referred to as "hair follicle tests", the analysis targets the hair strand, not the follicle beneath the scalp.
