Hair Follicle Drug Testing - Barnhill, IL

What it is, How it works

Hair examinations have increasingly become a formidable resource for identifying drug and alcohol consumption. Hair captures a comprehensive history of substances by encapsulating biomarkers within the strands as they grow. When obtained near the scalp, hair can reveal up to roughly a 3-month period of alcohol and other drug usage. Hair is easy to collect, challenging to tamper with, and simple to send.

A 1.5-inch fragment of about 200 hair strands (similar to the thickness of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the perfect sample for evaluation and validation. For EtG, add-ons, or tests exceeding 10 panels, 150mg of the hair sample is advisable. It’s suggested to measure the sample using a jeweler’s scale. If scalp hair is absent, a comparable quantity of body hair can be gathered. When mentioning head hair, it strictly means scalp hair. Body hair denotes all other types (facial, axillary, etc.).

Process Summary

The four crucial phases in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the initial handling of a sample within a lab’s framework. This step ensures that the sample was securely sealed and dispatched correctly, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any extra data input not available through an electronic custody chain system.

Screening entails a preliminary swift analysis for substance abuse indicators. Although Screening provides a budget-friendly approach to exclude drug usage in most samples, a screen that returns positive must be corroborated to stand in legal settings. Any samples that preliminarily test positive in Screening necessitate additional validation.

If a sample is speculatively positive in the Screening phase, additional hair is extracted from the original sample and prepped for Extraction. In this procedure, substances are drawn from hair at a notably lesser concentration than other techniques (for example, urine or oral fluid), underscoring why hair drug screening is the most intricate technique to execute.

Verification of any positive screen result is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation when needed. The complete laboratory sequence from Accessioning to Confirmation is scrutinized in accordance with both the CAP (College of American Pathologists) Hair categorization and the ISO / IEC 17025 standard accreditation.

Benefits of hair drug testing:

• Extended detection span: Hair drug tests can identify drug usage for up to 90 days, whereas urine tests have a shorter detection span.
• Challenges in evasion: Evading a hair drug test is predominantly arduous, enhancing result accuracy.
• Offers historical insight: It displays a pattern of substance use over an extended period, beyond recent activity.

Constraints:

• Incapable of detecting recent consumption: It requires roughly 5-7 days for substances to manifest in hair.
• Expense: Hair drug evaluations are commonly pricier than alternative methods.
• Result variations: Aspects like hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Despite often being termed "hair follicle tests", the analysis focuses on the hair strand, not the follicle beneath the scalp.
