Hair Follicle Drug Testing - Boquillas Crossing, TX

What it is, How it works

Hair tests are increasingly recognized as a potent means for spotting drug and alcohol consumption. Hair retains a prolonged record of alcohol and drug intake by embedding biomarkers within the strands as they grow. When sampled near the scalp, hair can reveal substance exposure over a span of up to approximately 90 days. Collecting hair is straightforward, somewhat resistant to tampering, and simple to send.

A hair sample measuring 1.5 inches, comprising around 200 strands (akin to the thickness of a #2 pencil), taken nearest to the scalp, will yield 100mg of hair—ideal for both screening and confirmation. For EtG, additional panels, or tests over 10 panels, a specimen of 150mg is advised. A jeweler's scale is recommended for precise weighing of the sample. If scalp hair is not available, an equal quantity of body hair may be utilized. Reference to head hair pertains solely to scalp hair, whereas body hair covers all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial incorporation of a sample into a lab's system. This step ensures that the sample is properly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and includes additional data entry not handled by an electronic chain of custody system.

Screening provides a preliminary assessment for substances of abuse. Though Screening is a budget-friendly method to dismiss drug use in most samples, a positive screen must be verified for legal admissibility. All presumed positive samples identified in Screening necessitate a follow-up confirmation.

Should a sample register positive in the Screening phase, additional hair from the initial specimen is taken for the Extraction process. During Extraction, drugs are isolated from hair at concentrations much lower than other techniques (like urine or oral fluid), which underscores why hair drug screening is technically challenging.

Confirmation of any positive Screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples are thoroughly washed before confirmation as fit. The complete lab procedure from Accessioning to Confirmation is reviewed under the CAP (College of American Pathologists) Hair designation and in line with accreditation to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can reveal drug use over a span of up to 90 days, unlike urine tests which have a shorter detection span.
• Resistance to manipulation: Hair tests prove challenging to manipulate, enhancing result credibility.
• Historical usage data: They supply a trend of drug use over time rather than just current consumption.

Limitations:

• Lags in detecting recent use: Detecting drugs in hair takes roughly 5-7 days.
• Expense: Hair tests usually cost more than alternative drug testing approaches.
• Result variability: Factors like hair color and individual growth variations can impact drug metabolite levels found in hair.

Note: Although frequently termed "hair follicle tests," the assessment analyzes the hair strand, 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing.
