Hair Follicle Drug Testing - Lake Lillian, MN

What it is, How it works

The use of hair tests has emerged as an effective method for identifying drug and alcohol consumption. Hair serves as a comprehensive record of substance use by capturing biomarkers within the strands as they grow. When obtained near the scalp, hair can reveal drug and alcohol usage within approximately a 90-day timeframe. Hair samples are not only straightforward to collect but also challenging to tamper with and convenient to transport.

A sample measuring 1.5 inches and containing roughly 200 strands (comparable to the diameter of a #2 pencil) from near the scalp can yield 100mg of hair, which is ideal for both screening and confirmation. For tests like EtG, additional analyses, or those exceeding 10 panels, a 150mg sample is recommended. It's advisable to use a jeweler’s scale for weighing the specimen. In cases where scalp hair is absent, a similar quantity of body hair is acceptable. When discussing head hair, we specifically mean scalp hair, while body hair encompasses all other types (such as facial and axillary hair).

Process Overview

The laboratory processing of drug tests involves four stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a sample into the laboratory system. This step involves ensuring the sample was sealed and transported correctly, generating a unique LAN (Laboratory Accessioning Number), and completing any extra data input not already managed by an electronic chain of custody system.

Screening is the preliminary assessment for substances of abuse. Although this step is an economical method to exclude drug use in most samples, a positive screening result requires confirmation to be deemed legally valid. Any samples that yield a preliminary positive result in Screening must undergo further confirmation.

If a sample tests presumptively positive in the Screening phase, additional hair is taken from the original specimen for the Extraction process. Here, substances are extracted from hair at significantly lower concentrations compared to other testing methods (e.g., urine or oral fluid), making hair drug screening one of the most challenging methodologies to execute.

Confirmation of any screening-positive result is achieved using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positive results undergo washing before confirmation as necessary. The entire lab procedure, from Accessioning to Confirmation, is conducted under the oversight of the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Lengthy detection period: Hair drug tests can reveal drug use for as long as 90 days, unlike urine tests, which have a shorter detection span.
• Hard to manipulate: Cheating a hair drug test is very difficult, ensuring more accurate outcomes.
• Supplies historical data: It offers a pattern of drug use over an extended period rather than only recent usage.

Limitations:

• Incapable of detecting recent use: It generally takes 5-7 days for substances to be traceable in hair.
• Expensive: Hair drug tests typically cost more than other drug testing approaches.
• Result variability: Hair color and personal differences in hair growth can influence the levels of drug metabolites in hair.

Note: Although frequently called "hair follicle tests," the analysis actually examines the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Lake Lillian, MN sees hair follicle testing surpassing urine testing in several ways. While traditional urine tests offer a snapshot of recent substance use, hair tests provide a detailed history over months.
