Hair Follicle Drug Testing - Forest Hill, MD

What it is, How it works

Hair testing is increasingly recognized as an effective means for identifying drug and alcohol use. By embedding biomarkers within the fibers of the hair, it provides a long-term history of substance intake. When sampled near the scalp, hair offers roughly a 3-month window for detecting alcohol and other substances. The collection of hair is straightforward, challenging to tamper with, and simple to transport.

A 1.5-inch portion of approximately 200 hair strands (around the width of a #2 pencil) closest to the scalp yields 100mg of hair, ideal for initial screening and confirmation. For EtG, additional tests or tests beyond 10 panels, 150mg of hair is advised. It is recommended to weigh the sample using a jeweler's scale. Should scalp hair be absent, an equivalent quantity of body hair can be utilized. When discussing head hair, it specifically pertains to scalp hair only, while body hair encompasses all other types (such as facial and axillary).

Process Overview

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

Accessioning deals with the initial integration of a sample into a laboratory’s framework. This step ensures the proper sealing and dispatch of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any additional required data entry absent from an electronic chain of custody system.

Screening conducts a preliminary and rapid assessment for drug abuse. As a cost-effective measure, it can rule out drug use in most samples; however, a positive result in Screening necessitates further confirmation for legal admissibility. Presumptively positive Screening samples require a subsequent confirmation.

In cases where Screening indicates a presumptive positive, additional hair is extracted from the original sample and prepared for Extraction. This stage involves extracting drugs from hair at a substantially reduced concentration compared to other techniques (e.g., urine or saliva), implicating hair drug screening as the most challenging method to execute.

Confirmation of positive screening outcomes employs GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to confirmation as required. The comprehensive laboratory procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair criteria and the standards accreditation of ISO/IEC 17025.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can unveil drug use for up to 90 days, whereas urine tests offer a shorter detection period.
• Difficult to manipulate: It is considerably difficult to deceive a hair drug test, thus enhancing result accuracy.
• Offers historical data: Enables a pattern of drug use over time, rather than merely recent consumption.

Limitations:

• Unable to detect recent use: It takes roughly 5-7 days for drugs to be identifiable in hair.
• Expense: Hair drug testing is typically more costly compared to alternative drug-testing methods.
• Result variability: Elements such as hair color and personal differences in hair growth can influence drug metabolite concentrations in hair.

Note: Although commonly termed as "hair follicle tests," these tests examine the hair strand rather than the follicle beneath the scalp.
