Hair Follicle Drug Testing - Demarest, NJ

What it is, How it works

Hair testing is highly regarded as a significant method for identifying drug and alcohol usage. The hair provides a comprehensive history of substances by embedding biomarkers within its growing strands. Hair samples cut close to the scalp offer nearly a 3-month detection period for detecting alcohol and drugs. Collecting hair is straightforward, relatively hard to tamper with, and ensures easy transportation.

A sample of 1.5 inches consisting of roughly 200 hair strands, equivalent to the diameter of a #2 pencil, near the scalp, yields 100mg of hair—the optimal amount for preliminary and confirmatory testing. For tests such as EtG, supplementary options, or over 10-panel analyses, 150mg is preferable. A jeweler’s scale is suggested for weighing. If there’s no scalp hair, an equivalent quantity of body hair may be collected. When mentioning head hair, it specifically indicates scalp hair; body hair includes all other categories (e.g., facial, axillary).

Process Overview

The key procedures in processing a drug test outcome in a lab comprise Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary handling of a sample within a lab system. This process verifies the sample’s proper sealing and shipment, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data entry that the electronic chain of custody might not cover.

Screening entails an initial, efficient assessment for substances. Though Screening is cost-effective for excluding drug presence in most samples, a positive result needs verification for legal admissibility. Specimens that are indicative of positivity in Screening require further confirmation.

Should a sample indicate positivity in the Screening phase, additional hair from the original collection is used for Extraction. This stage involves extracting drugs from hair at much lower concentrations compared to other methods (e.g., urine or saliva), making hair drug testing the most complex methodology.

Confirming any positive results from Screening is done via GC/MS, GC/MS/MS, or LC/MS/MS. All tentative positive specimens undergo washing as necessary before confirmation. The entire lab procedure from Accessioning to Confirmation meets both the CAP (College of American Pathologists) guidelines for Hair and is accredited according to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug assessments can recognize drug consumption up to 90 days, as opposed to urine assessments that have a shorter timeframe.
• Challenges in deception: Overcoming a hair drug test is very challenging, thus increasing result accuracy.
• Supplies historical insights: Offers insights into habitual drug use over time rather than just recent consumption.

Limitations:

• Incapable of identifying recent consumption: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Hair drug tests tend to be more costly than other testing methods.
• Result variation: Elements such as hair color and individual hair growth differences may influence metabolite concentration in the hair.

Note: Commonly termed as “hair follicle tests,” the analysis targets 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.
