Hair Follicle Drug Testing - Fork, MD

What it is, How it works

Acknowledged as a robust method for identifying drug and alcohol consumption, hair testing captures biomarkers within the fibers of the hair as it grows, providing a comprehensive history. Collected near the scalp, hair can indicate alcohol and drug use for roughly up to three months. Collection is straightforward, tampering is relatively hard, and shipping is uncomplicated.

A 1.5-inch portion consisting of about 200 hair strands (similar in size to a #2 pencil) closest to the scalp yields 100mg, which is the ideal sample size for initial and confirmatory testing. For EtG supplements and/or tests surpassing 10 panels, a specimen of 150mg is advisable. Utilizing a jeweler’s scale for weighing is recommended. Should scalp hair be unobtainable, an equivalent quantity of body hair is acceptable. References to head hair pertain solely to scalp hair. Body hair encompasses all other varieties (such as facial or axillary).

Process Overview

Drug test result processing involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary step where a sample is logged into the lab system. This process includes ensuring the sample was properly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and entering any additional information not supplied by an electronic chain of custody.

Screening acts as a preliminary assessment for drug presence. While it is a cost-efficient method to exclude drug usage in most cases, a positive result from screening needs confirmation for legal purposes. Samples flagged as presumptively positive in screening must undergo further confirmation.

If a screening indicates a presumptive positive, additional hair from the original sample is readied for Extraction. In this phase, drugs are extracted at much lower concentrations compared to other methods (such as urine or oral fluids), underscoring the complexity of conducting hair drug screening.

Confirmation of any positive screen is performed using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation if required. The entire procedure from Accessioning to Confirmation undergoes review under the CAP (College of American Pathologists) Hair classification and aligns with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can identify drug use up to 90 days post-use, as opposed to urine tests which detect more recent use.
• Resistance to tampering: The likelihood of successfully tampering with a hair drug test is low, ensuring the accuracy of results.
• Chronological insight: It offers insight into drug usage patterns over a span, not just recent consumption.

Limitations:

• Incapable of detecting recent use: There is a window of approximately 5-7 days before drugs become detectable in hair.
• Expense: Generally, hair drug testing incurs higher costs than other testing techniques.
• Result variability: Factors such as hair pigmentation and individual hair growth rates can influence drug metabolite levels within the hair.

Note: Commonly known as "hair follicle tests", this methodology examines the hair shaft instead of the follicle beneath the scalp.
