Hair Follicle Drug Testing - Williamson, NY

What it is, How it works

Hair testing emerges as an influential method for identifying drug and alcohol use. Through hair, a prolonged history of substance intake is revealed by encapsulating biomarkers within the strands as they grow. When cut near the scalp, hair offers an approximately 3-month timeframe for detecting alcohol and drugs. The collection of hair is straightforward, somewhat resistant to tampering, and convenient to transport.

A sample measuring 1.5 inches, consisting of roughly 200 hair strands (comparable to a #2 pencil's width), provides 100mg of hair, which is the optimal quantity for initial testing and confirmation. For EtG, additional examinations, and tests exceeding 10 panels, 150mg of the sample is advised. It is advisable to use a jeweler’s scale to weigh the specimen. If scalp hair isn't accessible, an equivalent quantity of body hair can be gathered. Head hair refers explicitly to scalp hair, while body hair encompasses all other types, such as facial and axillary hair.

Process Overview

The laboratory process for determining a drug test outcome includes four principal stages: Accessioning, Screening, Extraction, and Confirmation.

In Accessioning, a sample undergoes initial processing into the lab's system. This step ensures the sample was correctly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any missing data entry not provided by an electronic chain of custody system.

Screening serves as a preliminary and rapid assessment for drugs of abuse. Although Screening is cost-effective for ruling out drug use in most samples, a positive screening result requires Confirmation to be court-admissible. Samples that are initially positive in the Screening stage need a secondary confirmation.

Should a sample be initially positive during Screening, additional hair is extracted from the original sample and prepped for the Extraction stage. Here, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which challenges the performance of hair drug screening.

Any positive screening result undergoes Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleaned before Confirmation as needed. The comprehensive laboratory process, from Accessioning to Confirmation, adheres to the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, whereas urine tests have a narrower detection window.
• Cheating difficulty: Cheating a hair drug test is notably challenging, enhancing result reliability.
• Historical usage data: It shows a pattern of drug use over time, rather than only recent usage.

Limitations:

• Recent use detection: Drugs become detectable in hair approximately 5-7 days post-use.
• Cost: Hair drug testing typically incurs higher expenses compared to other testing methods.
• Result variations: Variables such as hair color and individual hair growth differences can influence drug metabolite concentrations in the hair.

Note: Referred to as "hair follicle tests," the actual analysis is conducted on 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.
