Hair Follicle Drug Testing - Dubuque, IA

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol use. It records a comprehensive timeline of alcohol and drug intake by embedding biomarkers within the strands of growing hair. When hair is taken near the scalp, it has the capacity to reveal drug and alcohol use over a period of up to approximately three months. The process of collecting hair samples is straightforward, relatively tamper-proof, and simple to transport.

An ideal sample consists of a 1.5-inch segment of roughly 200 hair strands (equivalent to the diameter of a #2 pencil) cut close to the scalp, producing about 100mg of hair, perfect for both screening and confirmation. For extended tests like EtG or more than 10 panels, a sample weighing 150mg is advisable. It's recommended to weigh the sample on a jeweler's scale. In instances where scalp hair is not available, an equivalent weight of body hair can be used. The term "head hair" specifically refers to scalp hair, whereas "body hair" encompasses all other hair types, including facial and axillary.

Process Overview

The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the initial integration of a sample into a lab's system, which includes confirming the sample's seal and shipment, allocating a unique LAN (Laboratory Accessioning Number), and completing any extra data input omitted by an electronic custody system.

Screening is a preliminary examination for substances of abuse. Although screening is a cost-efficient method to exclude drug use in most samples, a positive result necessitates confirmation for legal acceptability. Samples with presumptive positive results in Screening must undergo secondary confirmation.

In cases of presumptive positivity during Screening, additional hair is extracted from the original sample for preparation in the Extraction phase. Here, drugs are extracted from hair at notably lower concentrations than in alternative methods (e.g., urine or oral fluid), marking hair drug screening as one of the most complex methodologies.

Confirmation for any positive screening is achieved through GC/MS, GC/MS/MS, or LC/MS/MS methods. Before confirmation, all presumptive positive samples are cleaned as required. This entire laboratory procedure, from Accessioning to Confirmation, is audited under the rules of both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, compared to the shorter detection timeframe of urine tests.
• Challenge to falsify: Cheating a hair drug test is notably difficult, ensuring more reliable results.
• Reveals consumption patterns: It offers insights into drug use patterns over time, unlike tests focused solely on recent use.

Limitations:

• Incipient use undetectable: Detection of drugs in hair typically requires 5-7 days post-use.
• Expense: Hair drug testing generally incurs higher costs compared to other testing methods.
• Result variability: Factors including hair color disparities and individual hair growth rates can influence drug metabolite concentrations in hair.

Note: Although commonly termed "hair follicle tests," the procedure analyzes the hair strand rather than the follicle beneath the scalp.
