Hair Follicle Drug Testing - De Witt, AR

What it is, How it works

Hair analysis has emerged as a potent method for identifying substance use, including drugs and alcohol. Hair holds a comprehensive timeline of substance ingestion by encasing biomarkers within the fibers of its growing strands. When obtained close to the scalp, hair can reveal substance use over a span of roughly three months. It's straightforward to collect, relatively tamper-proof, and straightforward to send.

A 1.5-inch segment from near the scalp, consisting of about 200 hair strands (roughly comparable to a #2 pencil's diameter), provides 100mg of hair, which is optimal for both screening and verification. For EtG or advanced tests beyond 10 panels, 150mg is optimal. It's advisable to use a jeweler’s scale to weigh the sample. If scalp hair is not available, a comparable quantity of body hair is an alternative. Referencing head hair implies scalp hair specifically, while body hair encompasses other types (facial, axillary, etc.).

Process Overview

The four core stages in laboratory analysis of drug testing outcomes are Accessioning, Screening, Extraction, and Confirmation.

Accessioning signifies the initial integration of a sample into a lab’s system. This step checks that the sample has been properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any data entry missing from an electronic chain of custody.

Screening performs a preliminary drug abuse assessment. Though an economical means to discount substance use for most samples, a positive result at this stage demands confirmation to be legally valid. Samples suggesting positive results in the Screening process undergo additional confirmation.

Should a sample show presumptive positives during Screening, additional hair is extracted from the initial sample for Extraction. Here, substances are extracted from hair at significantly lower levels than other methods (e.g., urine or oral fluid), making hair drug testing the more challenging methodology.

Positive screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All positive candidates are cleansed prior to confirmation as required. The complete laboratory process—from Accessioning to Confirmation—undergoes scrutiny in compliance with both the CAP (College of American Pathologists) Hair standards and accreditation to ISO / IEC 17025 norms.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use up to 90 days prior, in contrast with urine tests that have shorter timelines.
• Hard to manipulate: Cheating a hair drug test is extremely difficult, assuring more accurate outcomes.
• Offers usage history: It yields a timeline of substance use over time rather than immediate usage.

Limitations:

• Doesn't capture recent use: Drugs in hair become detectable only after about 5-7 days.
• Expense: Hair drug testing typically costs more than other methods.
• Result variability: Elements such as hair color and individuals' hair growth rates can influence drug metabolite concentrations in hair.

Note: Although often termed "hair follicle tests", the analysis focuses on the hair strand itself and not the sub-scalp follicle.
