Hair Follicle Drug Testing - Hornick, IA

What it is, How it works

Hair testing is regarded as an effective means for identifying drug and alcohol consumption. Hair offers a prolonged record of alcohol and drug usage by capturing biomarkers within the hair's growing fibers. When gathered near the scalp, hair affords a detection period for alcohol and drugs of up to about three months. Hair collection is straightforward, relatively tamper-resistant, and simple to transport.

A 1.5-inch segment consisting of roughly 200 hair strands (similar in size to a #2 pencil) nearest the scalp will yield 100mg, the optimal quantity for testing and verification. For EtG, additional tests, and/or panels exceeding 10, a 150mg specimen is advised. We suggest weighing the sample using a jeweler’s scale. If scalp hair is not present, an equivalent amount of body hair can be gathered. When discussing head hair, we are specifically referring to scalp hair. Body hair includes all other varieties (facial, axillary, etc.).

Process Overview

The primary steps in laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the preliminary handling of a specimen within a laboratory's framework. This step involves confirming that the specimen was properly sealed and transported, allocating a unique LAN (Laboratory Accessioning Number), and finishing any remaining data entry absent from an electronic chain of custody system.

Screening comprises an initial expeditious check for substances of abuse. While Screening offers an economical method to eliminate drug usage in most specimens, a positive outcome must be confirmed for legal admissibility. Any presumptively positive specimens in Screening necessitate subsequent confirmation.

If a specimen shows presumptive positivity during Screening, additional hair is drawn from the starting specimen and prepared for Extraction. In this stage, drug extraction from hair occurs at a significantly lower concentration compared to other techniques (e.g., urine or oral fluid), which explains why hair drug screening is the most challenging technique to execute.

Confirmation of positive results from Screening is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing before confirmation as required. The complete laboratory workflow from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair classification and the accreditation compliant with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection window: Hair analysis identifies drug usage for up to 90 days, unlike urine tests, which offer shorter detection spans.
• Hard to falsify: Manipulating a hair drug test is highly challenging, ensuring result precision.
• Historical usage data: It offers a timeline of drug consumption over a period, not limited to recent use.

Limitations:

• Cannot identify recent consumption: Drugs become detectable in hair after roughly 5-7 days.
• Price: Hair drug analysis generally incurs higher costs than alternative drug testing methods.
• Result discrepancies: Factors like hair color and individual growth differences can impact drug metabolite levels in hair.

Note: Commonly called "hair follicle tests", the examination targets the hair strand, not the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

In Hornick, IA, hair follicle testing excels over traditional urine tests by offering a superior detection period and comprehensive reliability. Whereas urine tests detect recent consumption, hair tests trace drug use over an extended duration, making them the preferred choice when assessing long-term drug habits. This period leads to a more precise overview, reducing false negatives typically seen in urine analysis.

Extended Detection Window

In Hornick, IA, hair follicle testing’s extended detection window, reaching up to 90 days, is invaluable. It gives employers a thorough view of an individual's substance history, facilitating informed hiring and monitoring decisions. This extended period contrasts strongly with shorter detection offered by alternative methods, which miss patterns of regular use, thus affording greater control and insight for employers.

Tamper-Resistant Testing Method

Providing a robust tamper-resistant method, hair follicle testing in Hornick, IA, significantly limits the chances of adulteration, offering honest results. The test utilizes hair samples, which are difficult to alter, thus maintaining the test's integrity. This secure process ensures reduced risks of manipulation often encountered in other testing methods like urine analysis.
