Hair Follicle Drug Testing - Viola, IL

What it is, How it works

Hair analysis is now regarded as an effective method for identifying drug and alcohol consumption. It offers a prolonged timeline for tracking alcohol and other substances by embedding biomarkers in the strands of growing hair. When hair is taken near the scalp, it can reveal drug and alcohol use over an approximate three-month span. Hair collection is straightforward, challenging to tamper with, and convenient for transport.

Sampling a 1.5-inch segment of roughly 200 hair strands (comparable to a #2 pencil's diameter) closest to the scalp yields approximately 100mg of hair, which is the preferred sample size for screening and confirmation. For tests like EtG add-ons or those exceeding 10 panels, 150mg is advised. Using a jeweler's scale to weigh the specimen is recommended. If scalp hair is not available, an equivalent amount of body hair can be gathered. When mentioning head hair, it specifically refers to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).

Process Overview

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

In the Accessioning stage, the sample undergoes initial processing into the lab's system. This step ensures the sample was sealed and transported correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry absent from the electronic chain of custody system.

Screening performs a preliminary check for drugs of abuse. Although cost-efficient for excluding drug use in many samples, a positive result needs confirmation for legal admissibility. Samples that test positive initially do require further validation.

Samples testing positive in the Screening phase undergo additional preparation for Extraction, where more hair is extracted from the original sample. This phase isolates drugs at lower concentrations compared to other techniques (such as urine or oral fluid), making hair drug screening the most intricate methodology.

Positive screenings are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all samples presumed positive are washed as necessary. The comprehensive laboratory process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: It can detect drug consumption up to 90 days, unlike urine tests which offer a shorter detection window.
• Resistance to manipulation: Cheating a hair drug test is significantly difficult, enhancing result accuracy.
• Illustrates usage patterns: It reflects substance use patterns over time, not just recent consumption.

Limitations:

• Cannot identify recent consumption: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests tend to be pricier than alternative testing methods.
• Result variability: Factors like hair color and individual growth differences can influence drug metabolite concentrations in hair.

Note: Commonly termed as "hair follicle tests," the test evaluates the hair strand itself, not the follicle beneath the scalp.
