Hair Follicle Drug Testing - Steward, IL

What it is, How it works

Utilizing hair analysis is recognized as an effective method for identifying drug and alcohol consumption. Hair strands capture long-term evidence of alcohol and drug use by embedding biomarkers in the strand as it grows. When taken from near the scalp, hair can reveal a history of up to three months for alcohol and drug use. This method is easy to conduct, challenging to tamper with, and convenient to transport.

A 1.5-inch segment of approximately 200 hairs (roughly the thickness of a #2 pencil) from the scalp yields 100mg, which is the optimal sample quantity for both initial screening and confirmation. For EtG evaluations, add-on tests, and tests exceeding 10 panels, 150mg is preferred. It's advisable to weigh the collected hair on a jeweler’s scale. If scalp hair cannot be used, a comparable amount of body hair can substitute. The term head hair specifically denotes scalp hair; in contrast, body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The laboratory analysis of a drug test follows four core steps: Accessioning, Screening, Extraction, and Confirmation.

The Accessioning phase integrates a sample into the laboratory’s workflow, ensuring it was properly sealed and delivered, assigning a LAN (Laboratory Accessioning Number), and completing any necessary data input not already in an electronic chain of custody system.

Screening provides a preliminary overview to identify drug abuse. It is a cost-efficient approach to dismiss drug presence in most samples, although any positive result during Screening necessitates confirmation for legal validity, requiring a secondary verification for presumptive positives.

If the Screening indicates a presumptive positive, additional hair is sourced from the initial sample for the Extraction phase. Here, extraction of drugs occurs at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug analysis.

Positive results from Screening are verified through GC/MS, GC/MS/MS, or LC/MS/MS. All samples marked positive preliminary are washed before confirmation if needed. The entire process, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Long detection window: Hair drug testing identifies drug usage over a 90-day period, whereas urine tests offer comparatively shorter detection periods.
• Difficulty to cheat: The reliability of a hair drug test is heightened due to the difficulty in tampering with it.
• Provides historical data: This method outlines a drug use pattern over time, covering more than just recent usage.

Limitations:

• Cannot detect recent use: It takes roughly 5-7 days for drugs to be traceable in hair.
• Cost: Generally, hair drug testing incurs higher costs compared to alternative methods.
• Variations in results: Drug metabolite concentration in hair can be influenced by hair color and personal hair growth differences.

Note: Although often termed "hair follicle tests," the assessment actually examines the hair strand rather than the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

Hair Follicle Testing vs. Urine Testing in Steward, IL, shows a clear winner. Hair tests detect drug use over a significantly longer period, while urine tests are limited to recent usage. This provides a broader understanding of an individual's drug history.
