Hair Follicle Drug Testing - Laurel Mountain Park, PA

What it is, How it works

Hair testing is now acknowledged for detecting alcohol and drug use effectively. Hair captures a detailed history of substance intake by embedding biomarkers within the hair strand as it grows. When obtained near the scalp, hair can offer a detection timeframe of roughly 3 months for both alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and easy to mail.

A hair sample measuring 1.5 inches, comprised of around 200 strands (comparable to a #2 pencil), provides 100mg of hair, which is the optimal sample for both screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the specimen is advisable. It's suggested to weigh the specimen using a jeweler’s scale. If scalp hair cannot be collected, an equal amount of body hair is permissible. When referencing head hair, we exclusively mean scalp hair. Body hair includes all other hair varieties (facial, axillary, etc.).

Process Overview

The laboratory procedure for processing a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial integration of a sample into a lab’s system. This process involves confirming the sample's secure sealing and dispatch, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any extra data entry absent in an electronic chain of custody system.

Screening involves a preliminary swift assessment for substance abuse. Though Screening is a cost-efficient method for excluding drug usage in most samples, any positive screen requires confirmation for legal proceedings. Samples initially positive in Screening necessitate further confirmation.

If a specimen tests presumptively positive during Screening, additional hair is extracted from the original sample for Extraction. During this phase, compounds are withdrawn from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), explaining why hair drug testing is the most challenging methodology to execute.

Confirmation of any positive screen is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples undergo washing before confirmation where necessary. The complete lab process, from Accessioning through Confirmation, is examined in compliance with CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long visibility window: Hair drug tests can uncover drug usage for up to 90 days, unlike urine tests which offer a shorter visibility window.
• Difficult to deceive: It's highly challenging to deceive a hair drug test, rendering results more trustworthy.
• Reveals historical usage: It may illustrate a pattern of substance use over time, rather than recent intake alone.

Limitations:

• Cannot identify recent intake: It typically takes 5-7 days before drugs become detectable in hair.
• Expense: Hair drug tests tend to be pricier compared to alternative drug testing approaches.
• Result discrepancies: Aspects like hair color and individual growth variations can influence drug metabolite levels in hair.

Note: Despite often being termed "hair follicle tests", the analysis is performed on the hair strand and not on the hair 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.
