Hair Follicle Drug Testing - Des Moines, IA

What it is, How it works

Hair analysis is increasingly recognized as an influential method for identifying drug and alcohol consumption. Hair captures a prolonged history of substances by retaining biomarkers within the strands as they grow. When obtained near the scalp, the hair can offer a detection period of up to three months for various substances. Collection is straightforward, modification is challenging, and transportation is convenient.

A specimen measuring 1.5 inches, consisting of roughly 200 hair strands (akin to the circumference of a #2 pencil) taken nearest to the scalp yields 100mg, the preferred quantity for evaluation and verification. For EtG, additions, and/or examinations exceeding 10 panels, 150mg is advisable. We suggest weighing the material on a jeweler's scale. In instances where scalp hair cannot be sourced, an equivalent quantity of body hair is an alternative. References to head hair pertain strictly to scalp hair. Body hair denotes other varieties (e.g., facial, axillary).

Process Overview

The drug testing process in a lab comprises four principal stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to initially incorporating a specimen into the laboratory's system, ensuring proper sealing and dispatch, assigning a random LAN (Laboratory Accessioning Number), and adding any supplemental data absent from an electronic custody chain system.

Screening is an expedient preliminary examination for substance use. While Screening is an economical method to dismiss drug presence in most samples, a positive indication necessitates confirmation for judicial acceptance. Samples showing presumptive positivity in Screening demand further corroboration.

Should a specimen indicate positivity in Screening, additional hair is extracted from the initial sample for the Extraction process. Here, substances are isolated from hair at lower concentrations relative to methods like urine or oral fluid analysis, making hair drug testing notably complex.

Confirmation follows any positive screening outcome through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptively positive samples undergo a preliminary wash before further confirmation. The comprehensive lab procedure from Accessioning to Confirmation adheres to CAP (College of American Pathologists) Hair classification and meets ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests identify substance use for up to 90 days, unlike urine tests which have shorter detection periods.
• Hard to manipulate: Cheating a hair drug test is extremely difficult, enhancing result precision.
• Timeline insight: The test reflects a pattern of long-term rather than immediate use.

Limitations:

• Recent use limitation: Drugs become traceable in hair approximately 5-7 days post-consumption.
• Expense: Hair drug tests tend to incur higher costs compared to other testing methodologies.
• Results variation: Factors like hair color and personal growth rates may influence drug metabolite levels in hair.

Note: Commonly named "hair follicle tests," the examination actually evaluates the hair strand, not the underlying follicle.
