Hair Follicle Drug Testing - Salem, VA

What it is, How it works

Hair testing has increasingly been recognized as a robust method for detecting drug and alcohol consumption. Hair acts as a historical archive of alcohol and other substances by capturing biomarkers within the developing hair strand's fibers. When collected near the scalp, hair can offer up to nearly a 3-month window for detecting alcohol and other substances. Collecting hair is straightforward, relatively resistant to tampering, and easy to transport.

A sample measuring 1.5 inches with roughly 200 hair strands (approximately the size of a #2 pencil) closest to the scalp yields 100mg of hair, which is the ideal sample for testing and confirmation. For EtG, additional tests, and/or panels exceeding 10, a 150mg specimen is suggested. It's advisable to weigh the specimen using a jeweler’s scale. If scalp hair is inaccessible, an equivalent quantity of body hair can be collected. When mentioning head hair, it pertains solely to scalp hair, whereas body hair refers to all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result includes four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial examination of a sample within a laboratory's system, involving the verification of the sample's proper sealing and shipping, the assignment of a random LAN (Laboratory Accessioning Number), and the completion of any extra data entry not available through an electronic chain of custody framework.

Screening performs a preliminary rapid assessment for substances of abuse. While Screening offers a cost-efficient method to negate drug usage in most samples, a positive screen necessitates confirmation to be court-admissible. Presumptive positive samples in Screening require a secondary confirmation.

Should a sample indicate presumptive positivity during Screening, more hair is extracted from the initial specimen for Extraction. In this process, drugs are derived from hair at much reduced concentrations than alternative methodologies (e.g., urine or oral fluid), which is why hair drug screening presents the greatest challenge.

Confirmation for any positive screen result is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Prior to confirmation, all presumptive positive samples are cleansed as required. The comprehensive lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests reveal drug use for up to 90 days, as opposed to urine tests' shorter detection range.
• Cheating challenges: Cheating a hair drug test proves to be extremely difficult, thereby enhancing result accuracy.
• Historical information: It showcases a timeline of drug use over a duration, beyond just recent activity.

Limitations:

• Recent use detection shortcoming: It generally takes about 5-7 days for drugs to surface in hair.
• Expense: Hair drug testing tends to be pricier than other methods.
• Result variability: Elements like hair color and individual hair growth variances can influence drug metabolite concentration in hair.

Note: Though frequently referred to as "hair follicle tests", the test evaluates the hair strand and 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.
