Hair Follicle Drug Testing - Toms Brook, VA

What it is, How it works

Hair testing has emerged as a potent means for identifying drug and alcohol consumption. It offers a long-term record by encapsulating biomarkers within the fibers of growing hair strands. By collecting samples near the scalp, hair can offer up to a roughly 3-month detection period for substances. It's easy to collect, somewhat resistant to tampering, and convenient for shipping.

A sample measuring 1.5 inches with about 200 hair strands (approximately the thickness of a #2 pencil) near the scalp provides 100mg of hair, the perfect amount for screening and confirmation. For EtG, add-ons, and/or tests beyond 10 panels, a sample of 150mg is preferred. We advise measuring it with a jeweler’s scale. If scalp hair is inaccessible, an equivalent amount of body hair can be collected. When discussing head hair, we mean scalp hair exclusively. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The key steps in processing a drug test result in the lab include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails initially integrating a sample into a laboratory’s system. This step involves ensuring the sample's proper sealing and shipping, assigning it a random LAN (Laboratory Accessioning Number), and performing any additional data entry absent from an electronic chain of custody system.

Screening provides a preliminary check for drugs of abuse. Although it serves as a cost-effective method to dismiss drug use in most samples, positive screens must be confirmed for courtroom admissibility. Any samples presumed positive during Screening necessitate a secondary confirmation.

If a sample is indicated positive in the Screening phase, additional hair is taken from the original specimen for Extraction. Here, drugs are extracted from hair at much lower concentrations than other methods (e.g., urine or oral fluid), which makes hair drug screening the most challenging methodology.

Confirmation of any positive screening outcome is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing before confirmation as required. The entire lab procedure from Accessioning to Confirmation is vetted under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can discover drug use for up to 90 days, whereas urine tests have a shorter detection span.
• Hard to manipulate: It's very hard to falsify a hair drug test, increasing result accuracy.
• Offers historical insight: It can show a pattern of drug use over a period, not just recent intake.

Limitations:

• Incapable of detecting recent use: It takes about 5-7 days for drugs to manifest in hair.
• Expense: Hair drug tests typically cost more than other drug testing techniques.
• Result variations: Factors like hair color and individual hair growth divergences can influence drug metabolite concentrations in hair.

Note: While often termed as "hair follicle tests," the analysis targets the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
