Hair Follicle Drug Testing - Halfway, MD

What it is, How it works

Hair analysis is now recognized as an effective means for detecting substance use, including drugs and alcohol. Hair captures a historical record of drug and alcohol usage by embedding biomarkers within the strands as they grow. When hair is taken close to the scalp, it can offer a detection span of up to 3 months for alcohol and other substances. Hair is straightforward to gather, somewhat resistant to tampering, and simple to transport.

To obtain a 100mg sample for testing, a 1.5-inch segment comprising about 200 hair strands (approximately the thickness of a #2 pencil) is ideal. For EtG testing, additional analytes, and panels beyond 10, a 150mg sample is advisable. Using a jeweler’s scale for weighing the sample is suggested. If scalp hair is not available, a similar amount of body hair can be collected. Mention of head hair exclusively pertains to scalp hair, whereas body hair includes all other hair varieties (such as facial, axillary, and so on).

Process Overview

The process of deriving a drug test result in a lab consists of four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary integration of a sample into the laboratory's system. This phase ensures that the sample was correctly sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and fulfills any additional data entry requirements not covered by an electronic chain of custody system.

Screening conducts an initial rapid analysis for substance abuse. Although Screening is a cost-efficient initial step to exclude drug use in the majority of samples, a positive result needs further confirmation to be acceptable in court. Therefore, all samples that indicate potential positivity in Screening must undergo subsequent confirmation.

Should a sample indicate potential positivity during the Screening, additional hair is extracted from the initial sample and prepared for Extraction. During this phase, substances are removed from hair at significantly reduced concentrations compared to other methods (such as urine or oral fluid), which makes hair drug analysis rather complex.

Potential positives from Screening are verified through GC/MS, GC/MS/MS, or LC/MS/MS. Every presumed positive sample is cleansed before confirmation if necessary. The complete lab process from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair designation and holds accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug analyses can identify drug consumption for up to 90 days, unlike urine tests which have a more restricted detection window.
• Challenging to deceive: Manipulating a hair drug test is quite challenging, enhancing result reliability.
• Reveals historical usage: It can indicate a trend in substance use over time rather than just recent consumption.

Limitations:

• Inability to identify recent use: Drugs take about 5-7 days to become traceable in hair.
• Expense: Generally, hair drug analyses are pricier than other drug testing techniques.
• Result variability: Elements like hair color and individual hair growth can influence the concentration of drug metabolites in the hair.

Note: Despite being commonly known as "hair follicle tests," these analyses examine the hair strand rather than 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.
