Hair Follicle Drug Testing - Walker Mill, MD

What it is, How it works

Hair testing is now recognized as an effective method for identifying drug and alcohol consumption. Hair captures a comprehensive timeline of alcohol and other substances by embedding biomarkers within the strands as they grow. When sourced near the scalp, hair can detect alcohol and drugs for up to three months. The collection process is straightforward, the sample is hard to tamper with, and the shipping is uncomplicated.

A sample measuring 1.5 inches of roughly 200 hair strands (approximately the width of a #2 pencil) nearest the scalp yields 100mg, the optimum quantity for both preliminary screening and confirmation testing. For EtG, extended tests, or those beyond 10 panels, a sample size of 150mg is advised. Using a jeweler's scale to weigh the sample is recommended. If scalp hair cannot be collected, a similar quantity of body hair is acceptable. When discussing head hair, we specifically mean scalp hair, whereas body hair encompasses other hair types (facial, axillary, etc.).

Process Overview

The laboratory procedure for analyzing a drug test result comprises four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning denotes the initial sample intake process within a laboratory setting, ensuring the proper sealing and shipment of the sample, the assignment of a unique LAN (Laboratory Accessioning Number), and the completion of any necessary data entry absent from an electronic chain of custody.

Screening serves as a preliminary inspection for drug traces. This stage is both cost-efficient and effective for dismissing drug presence in most samples, although any positive result in Screening requires subsequent confirmation for legal acceptability. Samples found to be tentative positives in Screening necessitate further confirmation.

For samples flagged as potentially positive in Screening, additional hair is extracted from the primary sampling and prepped for the Extraction phase. During this stage, drug compounds are extracted at significantly lower concentrations than other testing methods (e.g., urine or oral fluid), making hair drug testing notably challenging.

Confirmation of a positive screening involves GC/MS, GC/MS/MS, or LC/MS/MS techniques. Any suspect samples undergo a wash before proceeding to confirmation if necessary. The complete lab protocol from Accessioning through to Confirmation undergoes a review adhering to both CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection period: Hair tests can trace drug use up to 90 days, whereas urine tests offer a narrower detection timeline.
• Challenges in manipulation: It is highly challenging to deceive a hair drug test, thus ensuring more reliable results.
• Provides historical usage: It outlines a usage pattern over time, unlike tests that only indicate recent consumption.

Limitations:

• Inability to identify recent use: Drugs become detectable in hair only after approximately 5-7 days.
• Expense: Compared to other testing forms, hair drug tests carry higher costs.
• Inconsistencies in outcomes: Hair color and individual growth rates can alter drug metabolite levels in hair.

Note: Commonly termed as "hair follicle tests," this evaluation examines the hair strand, not the follicle beneath the scalp.
