Hair Follicle Drug Testing - Clear Lake, IA

What it is, How it works

Hair analysis has emerged as an effective means for identifying drug and alcohol consumption. The fibers of hair strands capture biomarkers, providing a historical record of substance use that can be detected for up to three months when hair is sampled close to the scalp. Collecting hair is straightforward, challenging to tamper with, and easily transportable.

A 1.5-inch segment consisting of roughly 200 strands (approximately the diameter of a #2 pencil) near the scalp yields about 100mg, the optimal quantity for initial and confirmatory testing. For EtG, add-ons, and assessments exceeding 10 panels, 150mg of the sample is advisable. It is recommended to weigh the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent amount of body hair can be utilized. "Head hair" pertains specifically to scalp hair, while "body hair" encompasses all other hair types (such as facial and axillary hair).

Process Overview

The laboratory stages for obtaining a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning incorporates the initial sample integration into a lab’s system by ensuring proper sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and executing any supplementary data entry absent from an electronic chain of custody.[ SYSTEM]

Screening performs a preliminary assessment for drug presence. Though affordable and effective for ruling out usage on most samples, a positive screen necessitates confirmation to be valid in legal settings. Presumptive positives during Screening warrant further verification.

For samples flagged as presumptively positive in Screening, additional hair is collected from the primary specimen and readied for Extraction. Here, drugs are isolated from the hair at significantly lower concentrations than other testing methods (e.g., urine or oral fluid), which contributes to the complexity of hair drug screening.

Confirming positive Screening results is conducted through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Needed washes are applied to all presumptive positives before proceeding with confirmation. The entire procedural cycle from Accessioning through Confirmation undergoes scrutiny under the CAP (College of American Pathologists) Hair specification and complies with ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair testing can reveal drug use for as long as 90 days, unlike urine tests with shorter detection spans.
• Challenging to manipulate: Hair drug testing is notoriously difficult to deceive, enhancing result credibility.
• Provides usage trends: It offers insights into drug usage patterns over time, beyond just recent intake.

Limitations:

• Delayed detection: Newly used drugs may require 5-7 days before becoming detectable in hair.
• Expense: Hair tests generally incur higher costs than alternative testing methods.
• Result variability: Drug metabolite levels in hair can be influenced by factors like hair color and individual growth rates.

Note: Although commonly termed "hair follicle tests," the analysis focuses on the hair strand itself, rather than the follicle beneath the scalp.
