Hair Follicle Drug Testing - North Kensington, MD

What it is, How it works

Hair testing has gained recognition as a potent method for identifying drug and alcohol consumption. Hair offers an extended timeline of substance use by embedding biomarkers within the growing strand. When cut near the scalp, it can provide up to a 90-day window for detecting alcohol and other substances. Hair collection is straightforward, relatively resistant to tampering, and convenient to transport.

A 1.5-inch segment of approximately 200 hairs (similar in size to a #2 pencil) nearest to the scalp will yield 100mg, the optimal sample size for analysis and verification. For EtG add-ons or tests exceeding 10 panels, a 150mg sample is advised. We suggest using a jeweler’s scale for sample weighing. If scalp hair is unavailable, an equivalent quantity of body hair can be taken. When we mention head hair, it refers specifically to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning entails the initial entry of a sample into the lab’s system. This step ensures the sample is properly sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and completes any additional data not provided by an electronic chain of custody system.

Screening consists of a rapid preliminary check for drug abuse. While it is an economical method to eliminate drug use in most samples, a positive screen requires confirmation for legal acceptability. Any samples testing presumptively positive in Screening need secondary verification.

Should a sample test presumptively positive in Screening, extra hair is drawn from the remaining specimen and readied for Extraction. Here, drugs are isolated from hair at significantly lower concentrations than other techniques (e.g., urine or oral fluids), making hair testing one of the most challenging methodologies to undertake.

Verification of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with a presumptive positive are cleansed before verification as necessary. The complete laboratory protocol from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair tests can trace drug use for as long as 90 days, unlike urine tests which have a shorter span.
• Hard to falsify: Manipulating a hair drug test is notably challenging, resulting in more reliable results.
• Offers historical insight: It can trace drug usage patterns over time, not limited to recent consumption.

Limitations:

• Unable to detect recent use: Drugs typically become detectable in hair after about 5-7 days.
• Expensive: Hair drug testing is often pricier than other testing methods.
• Result variability: Elements like hair color and personal differences in hair growth can influence drug metabolite concentrations in hair.

Note: Commonly described as "hair follicle tests", the analysis actually examines 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.
