Hair Follicle Drug Testing - Granite Falls, MN

What it is, How it works

Hair analysis is now recognized as a robust method for detecting drug and alcohol consumption. The hair strands, by capturing biomarkers in the fibers, provide a comprehensive record of substance intake over an extended period. When strands are collected near the scalp, they offer a detection period extending up to roughly three months for alcohol and drugs. Hair is straightforward to collect, not easily tampered with, and convenient to transport.

A 1.5-inch segment of approximately 200 hair strands (similar in size to a #2 pencil) closest to the scalp equates to 100mg, which is the optimal sample size for analysis and verification. For EtG, add-ons, and/or tests exceeding 10 panels, a specimen weighing 150mg is advised. Utilizing a jeweler’s scale to weigh the sample is recommended. In the absence of scalp hair, an equivalent amount of body hair can be used. By head hair, we mean scalp hair specifically. Body hair includes all other types (facial, axillary, etc.).

Process Overview

The laboratory steps for processing a drug test result consist of Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary sample handling within the laboratory's framework. This step ensures the sample's proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and completes any supplementary data needed beyond the electronic chain of custody.

Screening offers an initial rapid assessment for drug presence. Although Screening is cost-effective for negating drug use in most cases, a positive screen necessitates confirmation to be legally valid. Samples deemed presumptively positive during Screening require further confirmation.

For samples displaying presumptive positives in Screening, additional hair is extracted from the initial batch and prepared for Extraction. This stage involves isolating drugs from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging to execute.

Positive results in Screening are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples displaying presumptive positives undergo washing before confirmation as required. The complete laboratory protocol from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair designation alongside accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests trace drug use for up to 90 days, unlike urine tests with limited detection periods.
• Difficult to manipulate: Cheating a hair drug test is notably challenging, thus ensuring more reliable results.
• Reveals usage patterns: Tracks drug use over an extended timeframe, not just recent consumption.

Limitations:

• Inability to identify recent use: Drugs become detectable in hair approximately 5-7 days post-consumption.
• Expense: Hair drug tests generally cost more than alternate testing approaches.
• Result variability: Factors like hair color and individual hair growth variations may influence drug metabolite concentrations in hair.

Note: Though often termed as "hair follicle tests", the assessment focuses on the hair strand, not the follicle beneath the scalp
