Hair Follicle Drug Testing - Queenland, MD

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol usage. Hair offers a prolonged historical record of substance use by embedding biomarkers in the fibers of the hair as it grows. When gathered near the scalp, it can reveal a drug and alcohol usage period of up to approximately 90 days. Hair is easy to gather, rather challenging to tamper with, and convenient to transport.

A sample of 1.5 inches consisting of around 200 hair strands (comparable to a #2 pencil) nearest to the scalp yields 100mg, which is the perfect sample for both screening and confirmation. For EtG, additional testing, and/or panels exceeding 10, 150mg is advised. It's advisable to weigh the hair sample using a jeweler’s scale. In instances where scalp hair isn’t available, an equivalent amount of body hair is acceptable. When discussing head hair, we solely mean scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory processes a drug test through Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase of processing a sample into a lab's system. This phase includes verification of the sample's proper sealing and shipment, generation of a random LAN (Laboratory Accessioning Number), and completion of any lacking data entry not covered by an electronic chain of custody system.

Screening is a preliminary check for drug abuse indicators. While it's a financially efficient method for ruling out drug use in many samples, a confirmed positive screen is needed for legal admissibility. Presumptive positives from Screening necessitate subsequent confirmation.

Should a sample yield a presumptive positive during Screening, additional hair is extracted from the original sample for the Extraction phase. In this stage, drug extraction from hair happens at significantly lower concentrations than in other methodology such as urine or oral fluid, making hair drug testing the most methodologically challenging.

Confirmation of positive Screening results is done through GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive samples undergo washing before the confirmation as necessary. The end-to-end lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair criteria and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can identify drug use extending to 90 days, in contrast to the shorter timeframe of urine tests.
• Difficulty in deception: Cheating a hair drug test is challenging, leading to more precise outcomes.
• Historical usage data: It illustrates a timeline of drug use over a span rather than immediate use.

Limitations:

• Cannot indicate recent use: Detectable drug presence in hair takes about 5-7 days.
• Expense: Hair drug testing typically incurs higher costs than other testing methods.
• Inconsistent results: Variables such as hair color and individual growth differences may impact drug metabolite levels in hair.

Note: Even though termed "hair follicle tests", the analysis actually targets the hair shaft and not the follicle embedded in 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.
