Hair Follicle Drug Testing - Martin City, MT

What it is, How it works

Hair analysis has emerged as a significant method for detecting alcohol and drug consumption. The hair captures and retains biomarkers within the strands as they grow, offering a comprehensive historical record of substance use. When taken from near the scalp, it allows for detecting substances for up to about 90 days. The collection of hair is straightforward, not easily tampered with, and convenient to transport.

Collecting a 1.5-inch piece made up of around 200 hair strands (similar in size to a #2 pencil) near the scalp yields 100mg, which is optimal for both screening and confirming. For EtG, add-ons, or tests over 10 panels, a 150mg sample is suggested. It's advisable to measure the weight of the sample using a jeweler’s scale. In the absence of scalp hair, an equal volume of body hair can be collected. References to head hair denote scalp hair specifically, whereas body hair references all other types, including facial and axillary hair.

Process Overview

The process of lab-based drug testing includes Accessioning, Screening, Extraction, and Confirmation.

In Accessioning, the initial processing incorporates entering the sample into a lab’s database, ensuring the sample's seal and shipment integrity, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.

Screening entails a rapid preliminary assessment for potential drugs. Though Screening is economical for initially ruling out drug usage in most samples, samples testing positive require subsequent confirmation for legal validity. All Screening samples that test as presumptively positive require additional confirmation.

For any sample with a preliminarily positive result in Screening, additional hair is extracted from the original sample to prepare for Extraction. During this phase, drugs are isolated from hair at much smaller concentrations relative to other techniques (e.g., urine or oral fluid), complicating hair drug screening more than other methods.

Confirming any screened positive result utilizes GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Post-Screening positive samples undergo washing before Confirmation as necessary. The complete lab procedure from Accessioning through Confirmation adheres to scrutiny under both CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can trace drug usage for up to 3 months, surpassing the shorter detection period of urine tests.
• Resistant to tampering: Defrauding a hair drug test is challenging, thus enhancing result accuracy.
• Chronological consumption data: The test unveils long-term usage trends, unlike detecting only recent intake.

Limitations:

• Recent usage not detectable: Drugs only become traceable in hair within approximately 5-7 days.
• Expense: Hair testing generally incurs a higher cost than other drug testing methods.
• Result variability: Differences such as hair pigmentation and individual growth rates can influence metabolite concentrations.

Note: Although commonly termed "hair follicle tests", this examination evaluates the hair strand rather than 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.
