Hair Follicle Drug Testing - Welcome, MN

What it is, How it works

The utilization of hair testing has gained recognition as an effective approach for identifying drug and alcohol consumption. Hair captures biomarkers in the fibers of its growing strands, thus offering a long-term record of substance use. Collected near the scalp, hair can reveal drug and alcohol consumption up to a 3-month window. Hair collection is straightforward, relatively resistant to tampering, and convenient for transportation.

Gathering a 1.5-inch section of approximately 200 hair strands close to the scalp yields 100mg, which is the optimal quantity for initial testing and verification. For EtG, add-ons, or testing beyond 10 panels, a specimen of 150mg is advisable. It's recommended to weigh the sample using a jeweler's scale. If scalp hair is unavailable, an equivalent amount of body hair can be used. When referring to head hair, it specifically means scalp hair, whereas body hair encompasses all other types (such as facial, axillary, etc.).

Process Overview

The laboratory processing of drug tests follows four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage where a sample is processed into the lab's system. This step involves checking the proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not included by an electronic chain of custody.

Screening is a preliminary and cost-effective method to check for substance abuse. While effective for most samples, any positive screen must be confirmed to be legally viable. Samples showing presumptive positivity in Screening need further confirmation.

Presumptively positive samples from the Screening stage have more hair extracted from the initial sample for the Extraction phase. Here, drugs are extracted at lower concentrations compared to other methods (e.g., urine or oral fluids), highlighting the complexity of hair drug screening.

Confirmation of positive results from Screening is conducted using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to confirmation as necessary. The end-to-end lab process from Accessioning to Confirmation is overseen under the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests offer detection of substance use for up to 90 days, which is longer than the detection period offered by urine tests.
• Difficulty to cheat: The resilience against tampering makes hair drug tests more reliable.
• Provides historical data: Reflects a pattern of substance use over time rather than just recent usage.

Limitations:

• Cannot detect recent use: Drugs become detectable in hair only after approximately 5-7 days.
• Cost: Typically, hair drug tests are more costly than alternative methods.
• Variations in results: Hair color and individual growth differences can impact drug metabolite concentration in hair.

Note: Although sometimes called "hair follicle tests", these tests assess the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing
