Hair Follicle Drug Testing - Brownsburg, VA

What it is, How it works

Hair analysis has emerged as a significant technique for identifying drug and alcohol consumption. Hair offers a comprehensive history of substance use by embedding biomarkers within the fibers of the hair as it grows. When sampled near the scalp, hair can reveal drug and alcohol intake over a span of up to 90 days. It is straightforward to collect, somewhat challenging to tamper with, and convenient to transport.

A sample measuring 1.5 inches with around 200 hair strands (about the girth of a #2 pencil) taken from the scalp will yield 100mg of hair, which is the optimal amount for examination and verification. For EtG, supplementary analyses, or assessments exceeding 10 panels, 150mg of the sample is advisable. We suggest using a jeweler's scale for weighing the specimen. In the absence of scalp hair, an equivalent quantity of body hair can be gathered. When we refer to head hair, we imply scalp hair solely. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The four primary phases in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary handling of a specimen into the lab's system. This procedure ensures that the sample was correctly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and finalizes any remaining data entry missing from an electronic chain of custody system.

Screening represents an initial rapid assessment for drug abuse. Although it is a cost-effective means to eliminate drug use for most samples, a positive screening result requires confirmation to hold up in court. Any samples suspected of being positive during Screening must undergo further confirmation.

If a sample is suspected positive during the Screening phase, additional hair is extracted from the original sample for the Extraction step. Here, drugs are isolated from the hair at significantly lower concentrations than other techniques (such as urine or oral fluid), making hair drug screening the most intricate methodology to execute.

Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Any suspected positive samples are cleansed before confirmation as necessary. The entire lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, whereas urine tests have a reduced window.
• Challenging to deceive: It is nearly impossible to undermine a hair drug test, enhancing result accuracy.
• Tracks usage patterns: It can indicate a drug use trend over time, not merely recent consumption.

Limitations:

• Inability to detect recent use: It takes roughly 5-7 days for drugs to be traceable in hair.
• Expense: Hair drug tests generally entail higher costs than other testing methods.
• Result fluctuations: Factors such as hair color and unique hair growth patterns can influence the concentration of drug residues in hair.

Note: Even though commonly labeled as "hair follicle tests", the test examines the hair strand itself, not the 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. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
