Hair Follicle Drug Testing - San Mar, MD

What it is, How it works

Hair testing is now recognized as a robust method for detecting drug and alcohol usage. It offers a historical perspective by capturing biomarkers within the hair strand's fibers during growth. When samples are taken near the scalp, they can reveal drug and alcohol use for up to roughly three months. Collection is straightforward, tampering is somewhat challenging, and shipping is convenient.

A 1.5-inch portion comprising approximately 200 hair strands (comparable to a #2 pencil's size) near the scalp yields 100mg, an optimal quantity for screening and confirmation. For EtG, additional tests, and/or more than 10 panels, 150mg of the hair sample is advisable. We suggest weighing the specimen on a jeweler's scale. If scalp hair isn't accessible, an equivalent body hair amount may be used. By head hair, we mean only scalp hair. Body hair denotes all other hair types (facial, axillary, etc.).

Process Overview

The laboratory process for a drug test result comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the initial entry of a sample into the laboratory’s system. It ensures that the sample was sealed and sent correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any supplementary data entry absent in an electronic chain of custody system.

Screening entails an initial swift assessment for drugs of abuse. Although cost-efficient for eliminating drug use in most cases, a positive screen must be confirmed for court admissibility. All preliminary positive samples in Screening necessitate further Confirmation.

In the event of a presumptive positive during Screening, additional hair is collected from the initial sample and prepared for Extraction. Here, drugs are drawn out from hair at substantially lower concentrations compared to other methods (e.g., urine or oral fluid), which contributes to hair drug screening's complexity.

Confirming any positive Screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Before Confirmation, all presumptive positive samples are cleansed as required. The complete laboratory procedure, from Accessioning to Confirmation, undergoes inspection 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 identify drug usage for up to 90 days, unlike urine tests with shorter detectability.
• Difficult to compromise: Hair drug tests are hard to cheat, enhancing result accuracy.
• Provides timeline data: It reveals a drug use pattern over time rather than just recent activity.

Limitations:

• Unable to detect recent use: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Hair drug testing tends to be costlier than alternative drug testing methods.
• Result variations: Factors like hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Though termed "hair follicle tests", this test analyzes the hair strand, 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.
