Hair Follicle Drug Testing - Vinson, OK

What it is, How it works

Hair testing emerges as an effective method for identifying drug and alcohol consumption. Hair serves as a long-term record of substance use by capturing biomarkers within the growing hair fibers. Collected near the scalp, it offers approximately a 3-month detection timeframe for drugs and alcohol. The collection process is straightforward, resistant to tampering, and simple to transport.

A 1.5-inch hair segment comprising about 200 strands (about the size of a #2 pencil) from the scalp is required to obtain 100mg of hair, which is optimal for both screening and confirmation. For EtG and tests exceeding 10 panels, 150mg of the sample is advised. A jeweler’s scale is suggested for weighing the sample. In cases where scalp hair isn't available, a comparable volume of body hair is acceptable. It's important to note that "head hair" refers exclusively to scalp hair, whereas "body hair" encompasses all other hair varieties (e.g., facial, axillary).

Process Overview

The main laboratory procedures for processing a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first step in a lab's system, involving verification of sample sealing and shipment, assigning a LAN (Laboratory Accessioning Number), and completing any necessary data entry not covered by an electronic chain of custody.

Screening conducts an initial inspection for drug substances. Though it's a cost-efficient means of excluding drug use in many samples, a positive screening must be verified for legal admissibility. Presumptive positives in screening always require further confirmation.

For samples deemed presumptively positive, additional hair is extracted from the initial sample and prepared for Extraction. This stage involves extracting drugs from hair at lower concentrations than other methods (e.g., urine or oral fluid), underscoring the challenges of hair drug screening.

Confirmation for any positive screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing as necessary before confirmation. The laboratory process, spanning Accessioning to Confirmation, aligns with both the CAP (College of American Pathologists) Hair standards and ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use up to 90 days, unlike urine tests with shorter windows.
• High accuracy: Cheating a hair drug test is difficult, enhancing result reliability.
• Historical use data: It depicts a pattern of drug use over time, not limited to recent usage.

Limitations:

• Limited recent use detection: Drugs appear in hair approximately 5-7 days post-use.
• Expense: Typically, hair drug tests cost more than other testing methods.
• Result variability: Hair color and personal hair growth rates can influence drug metabolite concentrations.

Note: Although sometimes called "hair follicle tests", the analysis focuses on the hair strand, not the underlying 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.
