Hair Follicle Drug Testing - King Arthur Park, MT

What it is, How it works

Hair testing is now considered a formidable technique for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and drug usage by embedding biomarkers within the fibers of the growing strand. If collected from the scalp, the hair can offer a detection window of up to nearly 3 months for alcohol and drugs. Hair is easy to gather, somewhat challenging to alter, and straightforward to transport.

A sample of 1.5 inches comprising roughly 200 strands of hair (approximately the thickness of a #2 pencil) nearest the scalp yields 100mg of hair, the optimal sample size for both screening and confirmation. For EtG, additional tests, and/or testing over 10 panels, a specimen of 150mg is advised. We suggest using a jeweler’s scale to weigh the sample. If scalp hair is unavailable, an equivalent sample of body hair may be used. When referring to head hair, it is specifically the scalp hair. Body hair refers to all other types (facial, axillary, etc.).

Process Overview

The core steps in laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the primary step of integrating a sample into the laboratory's framework. It entails confirming the sample's proper sealing and shipping, assigning an arbitrarily generated LAN (Laboratory Accessioning Number), and completing any additional data entry not outlined by an electronic chain of custody system.

Screening provides an initial rapid assessment for substances of abuse. While Screening is an economical way to eliminate drug usage for most samples, a positive result in Screening must be confirmed to hold validity in legal settings. Any samples indicated as potentially positive in Screening necessitate a further confirmation.

If a sample appears positive in the Screening process, additional hair is extracted from the initial specimen and readied for Extraction. In this stage, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which is what makes hair drug screening the most challenging methodology to execute.

Confirmation of any positive Screening results is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Every presumably positive sample is washed before confirmation as required. The complete laboratory procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use over a three-month period, compared to the shorter detection window of urine tests.
• Unlikely to be tampered with: Cheating a hair drug test is quite difficult, which augments the accuracy of the results.
• Offers historical insight: It reflects a timeline of drug use over months, not just recent consumption.

Limitations:

• Inability to detect recent usage: Drugs typically require 5-7 days to become detectable in hair.
• Expense: Hair drug tests are often costlier than other testing methods.
• Result variability: Factors such as hair color and individual growth rates can influence drug metabolite concentrations in the hair.

Note: Though often called "hair follicle tests", the test itself focuses on analyzing the hair strand, 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. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented.
