Hair Follicle Drug Testing - Langford, MD

What it is, How it works

Hair testing is increasingly regarded as a robust method for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug presence by embedding biomarkers within its fibers as the strand grows. When taken near the scalp, hair can reveal up to an estimated three-month timeframe for detecting alcohol and drugs. Collecting hair is straightforward, somewhat resistant to tampering, and easy to dispatch.

A 1.5-inch sample comprising roughly 200 hair strands (about the girth of a #2 pencil) nearest to the scalp yields 100mg, the optimal amount for screening and verification. For EtG, add-ons, or tests exceeding 10 panels, a 150mg sample is advised. We suggest measuring the sample using a jeweler's scale. If no scalp hair is available, an equivalent quantity of body hair might be gathered. When mentioning head hair, we specify only scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).

Process Overview

The primary stages in lab handling of drug test outcomes include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to initially processing a sample into a lab's framework. This involves confirming the sample's secure sealing and correct shipment, allocating a random LAN (Laboratory Accessioning Number), and filling any data gaps not captured by an electronic custody chain system.

Screening entails an initial swift assessment for drug abuse. Although it's cost-effective for excluding drug use in most samples, a positive screen demands confirmation to be court-valid. Any samples with presumptive positives in Screening necessitate further confirmation.

Should a sample show presumptive positivity in the Screening step, additional hair is retrieved from the original sample and prepped for Extraction. During this phase, drugs are drawn from hair at a lesser concentration than through other methods (e.g., urine or oral fluid), which is why hair drug screening is particularly challenging.

Confirmation of any positive screening is conducted using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo washing before confirmation as needed. The complete lab process from Accessioning to Confirmation is scrutinized under CAP (College of American Pathologists) Hair designation and in line with ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can identify drug usage for up to 90 days, unlike urine tests with a shorter timeframe.
• Difficulty to cheat: Cheating a hair drug test is extremely challenging, enhancing result accuracy.
• Provides historical data: It offers a pattern of drug use over time, not just recent incidents.

Limitations:

• Cannot detect recent use: It takes around 5-7 days for drugs to appear detectable in hair.
• Cost: Generally, hair drug tests are pricier than other testing approaches.
• Variations in results: Differences such as hair color and individual hair growth patterns can influence drug metabolite concentration in hair.

Note: Although often called "hair follicle tests", the analysis actually examines the hair strand rather than the scalp's hair follicle.
