Hair Follicle Drug Testing - Lessor, WI

What it is, How it works

The utilization of hair testing has been recognized as an effective means for uncovering drug and alcohol consumption. Hair offers a comprehensive archive of substance use by embedding biomarkers within the structure of the hair as it grows. When procured near the scalp, hair can reveal substance use over a span of almost three months. Collecting hair is straightforward, relatively tamper-resistant, and convenient to transport.

A sample measuring 1.5 inches, consisting of approximately 200 hair strands (comparable to the diameter of a #2 pencil) near the scalp will yield 100mg, an optimal quantity for both screening and verification processes. For EtG tests, add-ons, or more extensive panel tests beyond 10, a 150mg sample is suggested. We advise using a jeweler’s scale to measure the specimen. In the absence of scalp hair, an equivalent portion of body hair is acceptable. "Head hair" specifically denotes hair from the scalp. "Body hair" encompasses all other hair categories (including facial and axillary hair).

Process Overview

The laboratory processing of a drug test outcome consists of four crucial stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the introductory phase where a sample is entered into a laboratory's framework. This phase involves ensuring the sample has been properly secured and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any remaining data input not covered by an electronic chain of custody protocol.

Screening offers an initial inspection for substances of abuse. While it is a cost-efficient means to exclude drug consumption in most cases, a positive screening must undergo confirmation to be recognized in legal settings. All samples returning a presumptive positive in Screening mandate secondary confirmation.

Upon a presumptive positive in Screening, additional hair is isolated from the initial sample and readied for Extraction. During this phase, drugs are isolated from hair at concentrations lower than those in other methods (e.g., urine or oral fluid), highlighting the challenge of hair drug screening as a methodology.

Confirmation for any positive screening is achieved through GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positives undergo a washing process before confirmation if required. The entire sequence from Accessioning to Confirmation aligns with scrutiny under the CAP (College of American Pathologists) Hair category and complies with ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which offer a shorter detection span.
• Challenging to deceive: The high difficulty in falsifying a hair drug test enhances the reliability of outcomes.
• Chronological usage data: It can depict a pattern of substance use over a duration, not just recent consumption.

Limitations:

• Limits on recent use detection: Drugs only become detectable in hair after an estimated 5-7 days.
• Expense: Hair drug tests generally incur higher costs compared to other drug testing methodologies.
• Result variability: Elements like hair color and individual hair growth rates can influence the concentration of drug metabolites in hair.

Note: Though often labeled as "hair follicle tests", the procedure examines the hair strand itself and not the follicle beneath the scalp.
