Hair Follicle Drug Testing - Walkersville, 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 history of alcohol and other drug use by embedding biomarkers in the fiber of the hair as it grows. When collected near the scalp, hair can offer a detection period of up to roughly three months for alcohol and other substances. Hair is straightforward to gather, somewhat resistant to alteration, and simple to transport.

A 1.5-inch section consisting of approximately 200 hair strands (similar in size to a #2 pencil) closest to the scalp supplies 100mg of hair, which is the optimal sample amount for screening and confirmation. For EtG, extensions, and tests exceeding 10 panels, a specimen of 150mg is advised. It's recommended to weigh the sample using a jeweler’s scale. If scalp hair isn't available, an equal volume of body hair may be used. When referring to head hair, it specifically denotes scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).

Process Overview

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

The initial stage, Accessioning, includes processing a sample into the laboratory system, ensuring the sample was sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not provided by an electronic chain of custody.

Screening involves a preliminary swift check for substances of abuse. While Screening is an economical way to dismiss drug use for most samples, a positive screen must be confirmed for court admissibility. Any samples showing a presumptive positive in Screening need subsequent confirmation.

For samples that show presumptive positive results during Screening, further hair is extracted from the initial sample and prepared for Extraction. In this phase, drugs are isolated from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), marking hair drug testing as the most challenging technique to perform.

Confirmation of any positive screening outcome is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens undergo washing before confirmation if required. The complete laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for up to 90 days, unlike urine tests that have a shorter detection span.
• Resistance to tampering: It is exceptionally hard to alter a hair drug test, leading to more reliable outcomes.
• Historical data provision: It can outline a pattern of drug usage over time, not just recent usage.

Limitations:

• Inability to detect recent use: It requires roughly 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests typically cost more than other drug testing techniques.
• Result variations: Aspects like hair color and individual hair growth variations can influence the concentration of drug metabolites in the hair.

Note: The test is often referred to as a "hair follicle test," yet it examines the hair strand rather than the follicle beneath the scalp.
