Hair Follicle Drug Testing - Decorah, IA

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair captures a retrospective record of substances by embedding biomarkers within the developing hair shaft. When harvested near the scalp, it allows for an estimated 90-day detection span for alcohol and other substances. Hair is effortless to gather, somewhat challenging to tamper with, and straightforward to transport.

A 1.5-inch section containing approximately 200 hair strands (comparable to a #2 pencil in diameter) closest to the scalp will yield 100mg of hair, the optimal quantity for both screening and verification. For EtG tests, special requests, and/or assessments over ten panels, 150mg of the sample is advised. It's suggested to measure the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent portion of body hair may be used. When referencing head hair, it pertains solely to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory procedure for drug test analysis involves four major phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary handling of a sample within a lab’s database. This phase includes ensuring the sample was sealed and dispatched adequately, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data entry not accounted for by an electronic chain of custody system.

Screening is a preliminary quick assessment for drug presence. While Screening is an economical method to exclude drug intake for most samples, a positive result requires validation to be legally valid. Samples that yield a presumptive positive in Screening necessitate additional confirmation.

If a specimen tests presumptively positive in Screening, additional hair is extracted from the initial batch for Extraction. In this phase, substances are isolated from hair at a markedly lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening a complex methodology.

Validation of any positive screening outcome is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens are cleansed before confirmation as required. The comprehensive lab procedure from Accessioning to Confirmation is appraised under both the CAP (College of American Pathologists) Hair certification and the compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug assessments can trace drug use for up to 90 days, as opposed to urine analyses which offer a shorter detection window.
• Difficulty to cheat: Cheating a hair drug assessment is considerably arduous, enhancing result precision.
• Provides historical data: It supplies a trend of substance usage over time, not merely recent consumption.

Limitations:

• Cannot detect recent use: Drugs become detectable in hair approximately 5-7 days post-use.
• Cost: Hair drug evaluations generally incur higher expenses than alternative testing techniques.
• Variations in results: Elements such as hair pigmentation and individual growth disparities can influence drug metabolite concentrations in hair.

Note: While commonly termed as "hair follicle tests", the analysis actually examines the hair strand and not the follicle beneath the scalp.
