Hair Follicle Drug Testing - Rosario, WA

What it is, How it works

Hair testing has emerged as an influential method for detecting drug and alcohol consumption. Hair captures biomarkers within the strands, offering a long-term record of alcohol and drug usage. If gathered near the scalp, hair can reveal a detection timeline of around 3 months for these substances. Collection is straightforward, tampering is quite challenging, and shipping is convenient.

A hair sample measuring 1.5 inches, consisting of roughly 200 strands (the width of a #2 pencil) near the scalp, yields 100mg—the perfect sample weight for testing and confirmation. For EtG, additional tests or panels beyond 10, 150mg is suggested. Using a jeweler’s scale is advised for weighing the hair sample. Should scalp hair be unavailable, an equal portion of body hair is suitable. Head hair is defined as scalp hair solely, while body hair encompasses other types (such as facial, axillary, etc.).

Process Overview

The drug testing laboratory process encompasses four major stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample is initially processed into the lab's system. This step checks proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry not managed by an electronic chain of custody system.

Screening acts as a preliminary assessment for drugs of abuse. Although it's an economical method to eliminate drug use in the majority of samples, positive results require confirmation for legal admissibility. Samples testing presumptively positive in Screening must undergo further confirmation.

Should Screening suggest a positive result, additional hair is retrieved from the original sample for Extraction. Here, drugs are extracted from hair with a lower concentration than alternative methods (like urine or oral fluid), making hair drug screening a complex procedure.

For positive screenings, Confirmation is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive samples are washed before confirmation as needed. The entire procedure from Accessioning to Confirmation is reviewed according to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Detects drug use for up to 90 days, outlasting the shorter detection span of urine tests.
• Hard to falsify: Cheating a hair drug test is quite difficult, enhancing result reliability.
• Yields historical data: Reflects drug usage patterns over time, not just immediate consumption.

Limitations:

• Does not detect recent use: Drugs take about 5-7 days to become traceable in hair.
• Expense: Generally pricier than other drug test methods.
• Result variability: Factors like hair color and individual growth rates can affect drug metabolite concentrations.

Note: Often termed "hair follicle tests", these tests actually analyze 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.
