Hair Follicle Drug Testing - Glen Echo, MD

What it is, How it works

Analyzing hair has become recognized as an effective method for identifying the consumption of drugs and alcohol. Hair encapsulates a comprehensive record of alcohol and drug intake by embedding biomarkers within the strands of growing hair. When taken from near the scalp, hair can indicate drug and alcohol use over nearly a 90-day span. Hair is easy to obtain, relatively challenging to tamper with, and straightforward to transport.

A hair sample of 1.5 inches, consisting of approximately 200 hairs (similar in size to a #2 pencil), gathered closest to the scalp provides 100mg, which is the perfect quantity for testing and verification. For EtG, additional tests, and/or panels beyond 10, a 150mg sample is advisable. It's best to use a jeweler’s scale for accuracy. If scalp hair is not available, an equivalent volume of body hair can be used. References to head hair specifically mean scalp hair, whereas body hair refers to all other types (such as facial or axillary hair).

Process Overview

The key stages in a lab's drug testing method include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first step where a specimen is integrated into the lab's system. This step checks that the sample was properly sealed and delivered, generates a unique LAN (Laboratory Accessioning Number), and fills in any missing data not captured by an electronic chain-of-custody system.

Screening is a preliminary assessment for drugs of abuse. Though Screening is a cost-efficient strategy to discard drug usage in most samples, any positive result should be verified to be legally defendable. Samples flagged as potentially positive in Screening must undergo further confirmation.

When a sample shows potential positivity in the Screening phase, additional hair from the original batch is prepared for Extraction. This phase aims to draw out drugs from hair at much lower levels than other methods (e.g., urine or oral fluid), making hair drug screening a particularly complex technique.

Any preliminary positive Screening outcome is validated through GC/MS, GC/MS/MS, or LC/MS/MS analyses. Suspected positive samples undergo a washing protocol prior to final confirmation as necessary. The complete laboratory procedure, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair guidelines and ISO/IEC 17025 accreditation.

Benefits of hair drug testing:

• Extended detection period: Hair drug testing can reveal drug use spanning up to 90 days, surpassing the shorter windows of urine tests.
• High resistance to tampering: Due to difficulty in manipulation, hair drug testing ensures more reliable results.
• Tracks ongoing usage: Beyond recent activity, it can detect drug usage patterns over time.

Drawbacks:

• Cannot identify recent activity: Drugs become detectable in hair after roughly 5-7 days.
• Expense: Generally, hair drug testing is pricier than other methods.
• Result variation: Factors like hair color and individual hair growth differences can impact metabolite concentrations.

Clarification: Though often termed "hair follicle tests", it is the hair shaft that is examined, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why does hair follicle testing outperform urine testing in Glen Echo, MD? Hair tests have a broader detection window and higher accuracy.
