Hair Follicle Drug Testing - Emmorton, MD

What it is, How it works

Hair testing is increasingly recognized as a potent method for identifying drug and alcohol usage. Hair captures a lengthy history of alcohol and other drugs by embedding biomarkers within the fibers of the growing hair strand. When samples are procured close to the scalp, hair can offer approximately a 3-month detection span for alcohol and other substances. It is straightforward to collect hair, somewhat complex to tamper with, and convenient to transport.

A 1.5-inch segment of approximately 200 hair strands (comparable to the size of a #2 pencil) near the scalp yields 100mg of hair, the optimal sample for screening and verification. For EtG, add-ons, and/or testing beyond 10 panels, a 150mg sample is advised. Using a jeweler’s scale for specimen weighing is recommended. If scalp hair is not available, a comparable quantity of body hair can be taken. When discussing head hair, we refer solely to scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).

Process Overview

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

Accessioning involves the first processing stage of integrating a sample into a laboratory’s records. This step includes confirming the sample was sealed and dispatched correctly, allocating a random LAN (Laboratory Accessioning Number), and executing any supplemental data entry absent from an electronic chain of custody system.

Screening acts as an initial rapid assessment for drugs of abuse. While Screening provides a cost-effective means to eliminate drug usage in the majority of samples, a positive screen must be validated to stand in court. Instances of presumptive positives in Screening demand a subsequent confirmation.

For samples that register presumptive positives during the Screening phase, additional hair is drawn from the original specimen and prepped for Extraction. In this stage, drugs are isolated from hair at significantly lower concentrations than other techniques (e.g., urine or oral fluid), making hair drug testing the most challenging method to execute.

Confirmation of any positive screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo cleansing before confirmation as necessary. The complete laboratory course from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the compliance with ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection span: Hair drug tests identify drug consumption up to 90 days, unlike urine tests, which have a more limited detection range.
• Hard to manipulate: Manipulating a hair drug test is notably challenging, leading to more reliable outcomes.
• Reveals historical consumption: It can demonstrate a pattern of drug usage over time, beyond just immediate use.

Limitations:

• Inability to identify recent use: It takes about 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug tests are generally pricier compared to other drug testing approaches.
• Result disparities: Elements such as hair color and individual hair growth variations can impact the concentration of drug metabolites in hair.

Note: Commonly termed "hair follicle tests", the actual test evaluates the hair strand and not the follicle below the scalp.
