Hair Follicle Drug Testing - Cornlea, NE

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair captures a long-term history of these substances by embedding biomarkers within the fibers of the growing hair shaft. When taken close to the scalp, hair can offer up to a 3-month window for detecting alcohol and drugs. Hair is straightforward to collect, challenging to tamper with, and convenient to transport.

A 1.5-inch segment of roughly 200 hair strands (the diameter of a #2 pencil) closest to the scalp yields 100mg of hair, ideal for both screening and confirmation purposes. For EtG, supplementary tests, and/or analyses beyond 10 panels, 150mg of the sample is advised. Using a jeweler’s scale is recommended for weighing the sample. If scalp hair is absent, an equivalent amount of body hair can be used. By head hair, we mean scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory handling of a drug test result involves four main stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial input of a sample into a laboratory’s operations. This step confirms that the sample was sealed and shipped correctly, assigns it a random LAN (Laboratory Accessioning Number), and completes any supplemental data entry not covered by an electronic chain of custody system.

Screening offers a preliminary check for substance abuse. While it is a cost-efficient way to exclude drug usage in most samples, a positive screen must be verified for legal admissibility. Any presumptive positives from Screening require further confirmation.

If a sample tests positive in Screening, additional hair is taken from the original sample and prepared for Extraction. During this stage, drugs are isolated from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), highlighting why hair drug testing is the most complex to perform.

Positive screening results are confirmed using GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo washing as needed before confirmation. The overall laboratory process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair categorization and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can identify drug use for up to 90 days, unlike urine tests that have a shorter detection timeframe.
• Difficulty to cheat: Cheating a hair drug test is extremely difficult, ensuring more reliable results.
• Provides historical data: It reveals a drug usage pattern over time, rather than just recent usage.

Limitations:

• Cannot detect recent use: Drugs become detectable in hair approximately 5-7 days after use.
• Cost: Hair drug tests are generally pricier than other drug testing techniques.
• Variations in results: Hair color differences and personal variations in hair growth can influence drug metabolite levels in the hair.

Note: Although often termed "hair follicle tests", the test examines the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing
