Hair Follicle Drug Testing - Cullen, VA

What it is, How it works

Hair testing is recognized as an effective solution for identifying drug and alcohol use. Hair offers an extended timeline of alcohol and drug consumption by embedding biomarkers in the fibers of the developing hair strand. When obtained near the scalp, hair can reveal up to roughly a 3-month window for detecting alcohol and drugs. Hair is straightforward to collect, moderately challenging to tamper with, and simple to transport.

A sample measuring 1.5 inches, consisting of around 200 hair strands (about the width of a #2 pencil) nearest to the scalp, will supply 100mg of hair, which is the optimal sample for analysis and verification. For EtG, supplementary tests, and/or tests beyond 10 panels, 150mg of the specimen is advisable. We suggest weighing the sample with a jeweler’s scale. If scalp hair is not available, an equivalent quantity of body hair can be collected. When mentioning head hair, we refer solely to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

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

Accessioning encompasses the initial integration of a sample into a laboratory’s system. This includes authenticating that the sample was appropriately sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing further data entry not supplied by an electronic chain of custody system.

Screening performs a preliminary quick assessment for drugs of misuse. While Screening serves as a cost-efficient way to exclude drug usage for most samples, a positive screening result requires confirmation to be valid in court. Any samples presumed positive in Screening necessitate a subsequent confirmation.

Should a sample be presumed positive during the Screening phase, additional hair is taken from the original specimen and readied for Extraction. In this phase, drugs are extracted from hair at a significantly lower concentration compared to other methodologies (such as urine or oral fluid), which is why hair drug screening is the most challenging methodology to execute.

Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleansed before confirmation as needed. The complete laboratory process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can reveal drug usage for up to 90 days, contrasted with urine tests that have a shorter detection window.
• Difficulty to cheat: It is extremely challenging to cheat a hair drug test, rendering the results more precise.
• Provides historical data: It can reveal a pattern of drug use over a duration, not just recent consumption.

Limitations:

• Cannot detect recent use: Drugs become detectable in hair after approximately 5-7 days.
• Cost: Hair drug tests generally incur higher expenses than other drug testing techniques.
• Variations in results: Elements such as hair color and individual differences in hair growth can impact the concentration of drug metabolites in the hair.

Note: While frequently referred to as "hair follicle tests", the analysis is conducted on the hair strand and not on the hair follicle beneath the scalp

What's New In Hair Follicle Drug Testing according to the Hair Drug Testing Experts

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.

It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis.
