Hair Follicle Drug Testing - Solomons, MD

What it is, How it works

Seen as an influential mechanism, hair testing aids in identifying drug and alcohol consumption. Hair captures a prolonged history of substances by embedding biomarkers within the fibers of the hair strand as it grows. When hair is sampled near the scalp, it can detect substances like alcohol for up to a three-month window. The collection of hair is straightforward, challenging to tamper with, and convenient for shipping.

Taking a sample of 1.5 inches with roughly 200 hair strands (about the size of a #2 pencil) near the scalp yields 100mg of hair, perfect for both screening and confirmation. For comprehensive testing like EtG, extra panels beyond 10 require 150mg. It is advised to measure the specimen using a jeweler’s scale. If scalp hair isn't available, a similar quantity of body hair might be used. “Head hair” pertains solely to scalp hair, whereas “body hair” indicates other types like facial or axillary hair.

Process Overview

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

Accessioning is the first phase where a sample is input into the lab system, verifying proper sealing and shipping, assigning a LAN (Laboratory Accessioning Number), and preparing any extra data input absent in an electronic chain of custody system.

Screening performs a preliminary assessment for drugs of abuse. Although cost-efficient and effective for most samples, a positive screening result requires confirmation for court validity. Samples with tentative positive results in Screening need further confirmation.

If Screening indicates a possible positive, additional hair is extracted from the main sample for the Extraction phase. Here, drugs are isolated from hair at much lower concentrations than other methods (such as urine or oral fluid), making hair drug screening the most complex methodology.

Any positive screening results undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Sample washing occurs before Confirmation for necessary cases. The complete lab procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation of ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, versus urine tests with more limited detection.
• Cheating resistance: The difficulty in falsifying hair drug tests enhances result reliability.
• Historical usage data: It provides a timeline of drug consumption rather than recent usage alone.

Limitations:

• Lacks recent use detection: Drugs become noticeable in hair approximately 5-7 days post-use.
• Expense: Hair drug tests usually cost more than alternative testing methods.
• Result variation: Factors like hair color and individual growth variations may influence drug metabolite concentration in hair.

Note: Although commonly called "hair follicle tests," the actual analysis is of the hair strand, not the follicle below 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.
