Hair Follicle Drug Testing - Winterpock, VA

What it is, How it works

Hair analysis has emerged as an effective mechanism for identifying drug and alcohol consumption. The hair captures a timeline of substance intake by embedding biomarkers within its strands as it grows. When clipped near the scalp, hair samples can reveal alcohol and drug usage for up to roughly three months. Collecting hair is straightforward, challenging to tamper with, and simple to send.

A 1.5-inch segment containing roughly 200 hair strands (comparable to a #2 pencil's thickness) near the scalp yields 100mg of hair, which is the preferred quantity for both screening and confirmation. For EtG, add-ons, and/or examinations beyond 10 panels, a 150mg sample is advised. It's best to use a jeweler’s scale for accurate specimen measurement. If scalp hair isn't present, a comparable amount of body hair can be gathered. By mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other varieties (facial, axillary, etc.).

Process Overview

The laboratory procedure for processing a drug test result encompasses four major stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary handling of a sample into the laboratory’s framework. This process includes ensuring the sample was properly sealed and dispatched, allotting a random LAN (Laboratory Accessioning Number), and completing any lacking data entry that’s not integrated through an electronic chain of custody system.

Screening offers an initial rapid review for substances of abuse. Although Screening is an economical means to rule out drug use for most samples, a positive result from this stage requires confirmation for legal acceptance. Samples that test presumptively positive during Screening necessitate additional verification.

If a sample tests presumptively positive during the Screening phase, more hair is extracted from the initial sample and prepped for Extraction. This phase involves extracting drugs from hair at considerably lower concentrations than other techniques (e.g., urine or oral fluid), making hair drug analysis the most challenging approach to conduct.

Verification of a positive screening outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing before Confirmation as necessary. The full laboratory journey from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and in accordance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug analyses can identify drug use for as long as 90 days, unlike urine analyses which have a shorter detection span.
• Hard to deceive: It’s exceedingly challenging to deceive a hair drug analysis, thus ensuring more precise results.
• Reveals usage patterns: This method can uncover a history of drug use over time, not merely recent consumption.

Limitations:

• Inability to detect recent consumption: Drugs become detectable in hair around 5-7 days post-consumption.
• Expense: Hair drug analyses are typically pricier compared to other drug testing approaches.
• Outcome variability: Elements such as hair color and personal growth differences can influence the concentration of drug metabolites in the hair.

Note: Though often named "hair follicle tests", the analysis targets the hair strand and 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.
