Hair Follicle Drug Testing - Ellerslie, MD

What it is, How it works

Hair testing has gained recognition as a robust method for identifying drug and alcohol consumption. Hair offers a comprehensive history of alcohol and other substance usage by embedding biomarkers within the strands of growing hair. When taken near the scalp, hair can yield a detection window of up to 3 months for alcohol and other substances. Hair collection is straightforward, relatively hard to tamper with, and convenient to transport.

A sample of 1.5 inches of approximately 200 hair strands (equivalent to a #2 pencil) closest to the scalp will provide 100mg of hair, which is the optimal sample size for both screening and confirmation analyses. For EtG, add-ons, and/or tests exceeding 10 panels, a specimen of 150mg is advisable. We suggest using a jeweler’s scale to weigh the sample. If scalp hair isn’t available, an adequate amount of body hair can be gathered. When we mention head hair, we refer specifically to scalp hair. Body hair encompasses all other types (like facial, axillary, etc.).

Process Overview

The principal steps in processing a drug test in a laboratory setting include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial sample processing within a lab’s system. This involves ensuring the sample was properly sealed and shipped, generating a random LAN (Laboratory Accessioning Number), and completing any outstanding data entry not captured by an electronic chain of custody protocol.

Screening is a preliminary check for drugs of abuse. While cost-effective for ruling out drug usage across most samples, a positive screen requires confirmation to be legally sound in court. All samples flagged as positive in the Screening process need a secondary verification.

Should a sample test positive during Screening, additional hair is extracted from the initial batch and readied for Extraction. In this phase, drugs are isolated from hair at a notably lower concentration compared to other methods (e.g., urine or oral fluid), which is why hair drug testing is considered among the most challenging methodologies to execute.

A positive screening result is validated through GC/MS, GC/MS/MS, or LC/MS/MS. All samples that show presumptive positivity are cleansed before confirmation as necessary. The entire lab procedure, from Accessioning through to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection window: Hair tests can identify drug usage for as long as 90 days, unlike urine tests with a much shorter window.
• Hard to manipulate: Cheating a hair drug test is exceedingly difficult, thus results tend to be more reliable.
• Tracks drug usage patterns: It provides a timeline of drug consumption, rather than merely capturing recent usage.

Limitations:

• Cannot detect very recent usage: It takes around 5-7 days for drugs to appear in hair.
• Expensive: Hair drug tests generally cost more than other testing methods.
• Result variability: Elements like hair color and individual differences in hair growth can impact the levels of drug metabolites in the hair.

Note: Even though commonly referred to as "hair follicle tests", the test actually evaluates 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.
