Hair Follicle Drug Testing - Harveys Lake, PA

What it is, How it works

Hair analysis has become recognized as a highly effective instrument for identifying drug and alcohol consumption. Hair offers a comprehensive history of alcohol and drugs by embedding biomarkers within the growing strands. When gathered near the scalp, hair reveals up to a 3-month detection timeframe for both alcohol and drugs. It's easy to gather, somewhat challenging to tamper with, and straightforward to transport.

A sample measuring 1.5 inches, with about 200 strands (comparable to a #2 pencil), taken closest to the scalp provides 100mg of hair, which is perfect for both screening and confirmation. For tests such as EtG, additional panels, or those exceeding 10 panels, a recommendation is 150mg of the hair sample. It's suggested to weigh the sample with a jeweler’s scale. If scalp hair isn't available, a similar amount of body hair can be taken. "Head hair" specifies scalp hair, whereas "body hair" includes all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the initial integration of a sample into a lab's system, involving the confirmation of the sample's seal and proper shipping, assignment of a random LAN (Laboratory Accessioning Number), and completing any necessary data input absent from an electronic chain of custody system.

Screening performs an initial rapid assessment for drug abuse. Although Screening is a cost-efficient method to dismiss drug use in most samples, a positive result must undergo confirmation to be court-admissible. Samples suggested as positive in Screening necessitate further confirmation.

When a sample is flagged as presumptively positive during Screening, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are separated from hair at a much lower concentration than other methods (e.g., urine or oral fluid), making hair drug screening notably challenging to execute.

Confirmation of a positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples identified as presumptively positive are cleansed before confirmation if required. The complete laboratory process, from Accessioning to Confirmation, is reviewed both under the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, surpassing the shorter detection timeframe of urine tests.
• High resistance to tampering: Tampering with hair drug tests is notably difficult, ensuring more accurate results.
• Historical utilization insights: The tests offer an outline of drug use over time instead of merely indicating recent usage.

Limitations:

• Inability to detect recent usage: It usually requires 5-7 days for drugs to enter the detectable stage in hair strands.
• Higher expenses: Hair drug tests typically incur more costs than other testing approaches.
• Variable results: Elements like hair color and individual growth rates can impact drug metabolite concentration within hair.

Note: Though frequently termed "hair follicle tests", the analysis is conducted on the hair strand itself and 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.
