Hair Follicle Drug Testing - Knoxville, IL

What it is, How it works

Hair analysis is now recognized as an effective method for identifying drug and alcohol consumption. Hair captures a comprehensive history of substances by embedding biomarkers within the hairs as they grow. By gathering samples near the scalp, hair can reveal alcohol and drug use over a period of nearly three months. The collection process is straightforward, relatively tamper-resistant, and the samples are easy to transport.

A sample measuring 1.5 inches, comprising roughly 200 hair strands (approximately akin to the size of a #2 pencil) nearest to the scalp, supplies 100mg of hair, which is the preferred quantity for both screening and verification. For EtG, additional testing, or panels exceeding 10, gathering 150mg is advised. We suggest employing a jeweler’s scale for specimen measurement. In instances where scalp hair is unobtainable, a comparable quantity of body hair is an alternative. The term head hair is specifically used for scalp hair only. All other types, including facial and axillary hair, are referred to as body hair.

Process Overview

The laboratory processing of drug test results entails four fundamental steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial introduction of a sample into a lab’s framework. It encompasses ensuring the sample's secure sealing and proper shipment, allocating a unique LAN (Laboratory Accessioning Number), and inputting any supplementary information absent from an electronic chain of custody.

Screening involves a preliminary, expedient check for common drugs of abuse. Despite it being a cost-efficient means to eliminate drug presence in most samples, a positive screening necessitates confirmation to hold up in court. Any samples showing potential positivity during Screening require a follow-up confirmation.

Should a sample exhibit presumptive positivity during Screening, additional hair is sourced from the original collection and prepared for Extraction. Here, drugs are extracted at substantially lower concentrations than seen in alternative methods (like urine or oral fluid), highlighting the complexity of performing hair drug testing.

Confirmation for any sample testing positive through screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positives undergo washing as necessary prior to confirmation. The complete laboratory procedure from Accessioning through Confirmation is thoroughly vetted under the CAP (College of American Pathologists) Hair guideline and is certified to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests offer drug detection capability for up to 90 days, compared to the shorter span typical for urine tests.
• Difficult to evade: Avoiding a positive hair drug test through tampering is challenging, ensuring more reliable outcomes.
• Reveals usage patterns: It illustrates a timeline of drug consumption, as opposed to mere recent intake.

Limitations:

• No immediate use detection: Drugs become detectable in hair after roughly 5-7 days.
• Expense: Hair drug tests generally incur higher costs compared to other testing methods.
• Result variability: Hair color and individual growth variances can impact drug metabolite levels in hair.

Note: These tests, often called "hair follicle tests", actually analyze the hair strand rather than the follicle below the surface.
