Hair Follicle Drug Testing - Croom, MD

What it is, How it works

Hair testing is regarded as an effective method for identifying drug and alcohol consumption. The hair fiber captures biomarkers, offering a prolonged history of substances like alcohol, providing detection up to roughly 90 days when taken near the scalp. Collecting hair is straightforward, hard to tamper with, and easy to transport.

An ideal sample for analysis comprises a 1.5-inch hair segment, roughly 200 strands (comparable to a #2 pencil), yielding 100mg of hair. For advanced tests like EtG and those exceeding 10 panels, a 150mg sample is advised. Use a jeweler’s scale for precise weighing. In the absence of scalp hair, collect an equivalent amount of body hair. The term head hair specifically refers to scalp hair, whereas body hair includes all other types (facial, axillary, etc.).

Process Overview

The key phases in laboratory drug testing are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the sample's entry into the laboratory system, ensuring proper sealing and shipment, assigning a LAN (Laboratory Accessioning Number), and completing any missing data not covered by electronic custody systems.

Screening provides an initial check for drug abuse. Though Screening is an economical method for excluding drug usage in most samples, positive results require confirmation for legal validity. Presumptively positive samples from Screening necessitate secondary confirmation.

Should a sample be initially positive in Screening, additional hair is extracted from the sample for Extraction. This phase retrieves drugs from hair at lower concentrations than other methods like urine or oral fluid, contributing to the complexity of hair drug testing.

Confirmation for any positive screens employs GC/MS, GC/MS/MS, or LC/MS/MS techniques. Positive samples undergo washing prior to confirmation as necessary. The entire testing process, from Accessioning to Confirmation, undergoes review under CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair tests can detect drugs for 90 days, unlike urine tests with shorter detection spans.
• Hard to falsify: Cheating a hair test is challenging, ensuring more reliable results.
• Delivers usage history: It shows drug usage trends over time, not only recent consumption.

Limitations:

• Inability to identify recent use: Drugs become detectable in hair after about 5-7 days.
• Costly: Hair tests are typically pricier than alternative testing methods.
• Result variability: Hair color and individual growth rates can influence drug metabolite levels in hair.

Note: Commonly termed as "hair follicle tests", this procedure actually examines 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.

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.
