Hair Follicle Drug Testing - La Villita, NM

What it is, How it works

Hair assessment has emerged as an effective method for identifying drug and alcohol consumption. Hair strands encapsulate a prolonged history of substances by preserving biomarkers within the fiber matrix. When taken near the scalp, hair can reveal up to a 3-month timeframe of both alcohol and drug usage. Collection of hair is straightforward, relatively challenging to tamper with, and simple to send.

A 1.5-inch sample, roughly consisting of 200 hair strands (comparable in diameter to a #2 pencil), nearest to the scalp yields 100mg of hair, providing the ideal quantity for both preliminary and confirmatory analysis. For EtG and additional panels exceeding 10, a 150mg hair specimen is advised. Measuring the specimen on a jeweler’s scale is recommended. If scalp hair is inadequate, an equivalent amount of body hair can be used. "Head hair" pertains solely to scalp hair, while "body hair" includes all other types (such as facial or axillary hair).

Process Overview

The core steps for lab processing of a drug testing result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning initiates the entry of a sample, ensuring it was properly sealed and delivered, assigning it a unique LAN (Laboratory Accessioning Number), and completing any supplementary data entry not covered by an electronic chain of custody.

Screening provides a preliminary check for substance misuse. Though a cost-efficient approach for negating drug use in most samples, a positive screen necessitates confirmation for legal admissibility. Samples with positive indicators during Screening require a secondary affirmation.

For samples indicating potential positive results during Screening, additional hair is extracted from the primary batch and prepared for Extraction. During this phase, substances are extracted from hair at concentrations significantly lower than in urine or oral fluid methodologies, illustrating the complexity of hair drug testing.

Confirmation of a positive screen result utilizes GC/MS, GC/MS/MS or LC/MS/MS technology. All samples hinting at positive results undergo washing before confirmation as needed. The complete process, from Accessioning through Confirmation, aligns with CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection timeline: Hair tests can reveal drug use up to 90 days past, whereas urine tests offer a significantly shorter period.
• Challenge to subvert: Hair drug tests are notoriously hard to deceive, ensuring better result reliability.
• Provides insight over time: It reveals not only recent usage but also a trend of drug consumption over an extended term.

Limitations:

• Delayed detection: Drugs become apparent in hair approximately 5-7 days post-use.
• Expense: Hair tests typically come at a higher cost than alternative testing methods.
• Result variability: Hair color and individual hair growth rates can influence metabolite concentration in hair samples.

Note: Commonly called "hair follicle tests," the analysis focuses on the hair strand rather than the subscalp follicle.

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. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
