Hair Follicle Drug Testing - Four Corners, MD

What it is, How it works

Hair analysis is recognized as a robust method for identifying drug and alcohol consumption. Hair offers an extended historical record of substance use due to the entrapment of biomarkers within the growing strands. When taken from near the scalp, it can reveal alcohol and drug use for nearly three months. Collecting hair is straightforward, challenging to tamper with, and easy to transport.

A sample size of 1.5 inches comprising roughly 200 strands (similar to a #2 pencil) from nearest the scalp garners 100mg of hair, serving as an optimal specimen for testing and verification. For EtG, additional tests, or over 10 panels, a collection of 150mg is advised. We suggest measuring the sample using a jeweler’s scale. If scalp hair is not available, an equivalent quantity of body hair may be utilized. Head hair specifically refers to scalp hair, while body hair includes all other types (facial, axillary, etc.).

Process Overview

In laboratory testing for drug results, there are four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning signifies the sample’s preliminary integration into the lab’s framework. This step verifies the sample’s sealed and properly shipped status, allocates a random LAN (Laboratory Accessioning Number), and accomplishes any additional necessary data entry not facilitated by an electronic chain of custody.

The Screening process entails a preliminary evaluation for drug presence. Although Screening is a cost-efficient method for excluding drug usage in most cases, a positive screen requires confirmation to be court-admissible. Presumptuous positives in Screening necessitate subsequent verification.

When a sample tests presumptively positive during Screening, more hair is extracted from the original sample for the Extraction phase. Drugs are extracted from hair at notably low concentrations, making it a more challenging method compared to urine or oral fluid tests.

Confirmation of screening positivity is executed through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples presumed positive are washed before confirmation if needed. The entire lab protocol from Accessioning to Confirmation complies with both the CAP (College of American Pathologists) Hair directive and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests identify drug use for up to 90 days, while urine tests have a shorter detection period.
• Hard to manipulate: Cheating on a hair test is extremely difficult, ensuring reliable results.
• Offers usage history: It reveals drug use patterns over time, not just recent consumption.

Limitations:

• Incapable of recent use detection: Drugs become detectable in hair within 5 to 7 days.
• Expense: Hair drug tests usually surpass the cost of other testing methods.
• Result variability: Factors such as hair color and individual growth differences may impact drug metabolite concentration.

Note: Often called "hair follicle tests", these assessments examine the hair shaft, 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. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
