Hair Follicle Drug Testing - Swea City, IA

What it is, How it works

Hair analysis is now acknowledged as an effective method for identifying alcohol and drug consumption. By embedding biomarkers within the hair during its growth, hair presents a prolonged record of drug and alcohol use. Collecting samples near the scalp can offer a detection timeframe of up to three months for such substances. Hair sample collection is straightforward, not easily tampered with, and simple to transport.

A sample measuring 1.5 inches, comprising around 200 hair strands (roughly equivalent to the girth of a #2 pencil) near the scalp, yields approximately 100mg of hair, which is ideal for both screening and confirmation. For EtG, additional tests, and/or those beyond 10 panels, a specimen amounting to 150mg is advisable. It is advisable to weigh the specimen with a jeweler’s scale. Should scalp hair be inaccessible, an equivalent volume of body hair can be used. "Head hair" specifically refers to scalp hair alone, while "body hair" encompasses all other types, including facial and axillary hair.

Overview of the Process

The test result processing in a lab encompasses four central stages: Accessioning, Screening, Extraction, and Confirmation.

In the Accessioning phase, the sample first enters the laboratory system. This entails confirming the correct sealing and shipping of the sample, allocating a random LAN (Laboratory Accessioning Number), and populating any missing information not supplied by an electronic chain of custody.

Screening conducts a rapid preliminary check for misuse of drugs. It is an efficient way to eliminate drug usage in most samples; however, for court acceptability, positive results require confirmation. Those samples with presumptive positive results during Screening need a subsequent confirmation.

Should a sample show a presumptive positive in Screening, additional hair is extracted from the original specimen for the Extraction stage. This step involves retrieving drugs from hair at significantly lower concentrations than other methods such as urine or oral fluid, which makes hair drug screening notably challenging to administer.

Positive screening outcomes are verified through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation when necessary. The comprehensive laboratory process from Accessioning to Confirmation undergoes review following both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation standards.

Benefits of hair drug analysis:

• Extended detection period: Can identify drug use for up to 90 days, unlike urine tests with shorter detection spans.
• Hard to manipulate: Its resistance to tampering makes the outcomes more reliable.
• Reveals consumption patterns: It not only indicates recent use but also shows historical drug usage trends.

Drawbacks:

• Inability to detect recent usage: Drugs become detectable in hair approximately 5-7 days post-consumption.
• Expense: Typically costlier than other drug testing methods.
• Result variability: Influenced by factors like individual hair growth rates and color, influencing drug metabolite concentrations.

Note: Often termed a "hair follicle test", the analysis is on the strand of hair, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Swea City, IA, hair follicle testing surpasses traditional urine tests due to its superior detection accuracy and reliability. Unlike urine tests, which often only capture recent drug use, hair tests provide a broader snapshot of an individual's substance history.

The extensive detection window of hair testing makes it possible to identify drug use over months, as opposed to the limited timeframe urine tests offer, ensuring a more holistic approach to drug screening.

Extended Detection Window
