Hair Follicle Drug Testing - Glen Burnie, MD

What it is, How it works

Hair testing has emerged as a potent means for detecting drug and alcohol consumption. Hair offers an extended timeline of alcohol and drug history by embedding biomarkers within the fibers of the hair strand as it grows. When gathered close to the scalp, hair can provide a detection period of up to roughly 3 months for alcohol and other drugs. Hair is straightforward to collect, relatively hard to tamper with, and simple to transport.

A 1.5-inch segment of approximately 200 hair strands (about the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the ideal sample size for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advisable. We suggest measuring the specimen on a jeweler’s scale. If scalp hair cannot be collected, an equivalent quantity of body hair can be used. When discussing head hair, we specifically mean scalp hair. Body hair encompasses all other types such as facial, axillary, etc.

Process Overview

The laboratory processing of a drug test outcome consists of the four main stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the preliminary processing of a sample into the lab's system. This step involves ensuring the sample was appropriately sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not accommodated by an electronic chain of custody system.

Screening entails an initial rapid assessment for drugs of abuse. While Screening is a cost-efficient method to exclude drug usage in most samples, a positive screen requires confirmation to be legally admissible. Any samples appearing presumptively positive during Screening must undergo a secondary confirmation.

If a sample tests presumptively positive during the Screening phase, additional hair is extracted from the original sample and prepared for Extraction. During this phase, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to execute.

Confirmation of any positive screening result is conducted using techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The comprehensive laboratory procedure from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter detection range.
• Difficult to falsify: Hair drug tests are challenging to manipulate, leading to more reliable results.
• Offers historical data: Provides a pattern of drug use over time rather than just recent usage.

Limitations:

• Inability to detect recent use: It generally takes 5-7 days for drugs to become detectable in hair.
• Cost: Hair drug tests tend to be pricier compared to other drug testing methods.
• Variability in results: Elements such as hair color and individual differences in hair growth can influence drug metabolite concentrations in hair.

Note: Although commonly called "hair follicle tests", the test actually analyzes the hair strand, not the follicle beneath the scalp.
