Hair Follicle Drug Testing - Hill City, MN

What it is, How it works

Hair testing has gained recognition as an effective means for identifying drug and alcohol use. Hair strands offer a long-lasting record of alcohol and other drugs by capturing biomarkers within the growing hair's fibers. A sample collected near the scalp can reveal drug or alcohol usage for up to around a 3-month period. Hair is easy to obtain, hard to tamper with, and simple to transport.

Gathering a 1.5-inch segment of approximately 200 hairs (comparable to a #2 pencil) near the scalp yields 100mg of hair, which is optimal for analysis and verification. For EtG, additional tests, and/or panels beyond 10, 150mg of the sample is advised. It is suggested to weigh the sample using a jeweler's scale. If scalp hair is not an option, a similar amount of body hair can be taken. When discussing head hair, we specifically mean scalp hair. Body hair refers to all other hair types (facial, axillary, etc.).

Process Overview

The key phases in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first step of incorporating a sample into a lab’s system. This involves confirming that the sample was properly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not available from an electronic chain of custody system.

Screening is a preliminary assessment for drug abuse. Though Screening is an economical way to dismiss drug use in most samples, a positive result must be confirmed for legal acceptance. Any samples that yield a presumptive positive in Screening need secondary confirmation.

Should the sample test presumptively positive during Screening, more hair is extracted from the original specimen to prepare for Extraction. During this phase, drugs are removed from hair at a significantly lower concentration than other methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to undertake.

Confirmation of any positive screening result is accomplished using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results undergo washing before confirmation as required. The complete lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter timeframe.
• Difficult to deceive: Cheating a hair drug test is very challenging, enhancing result accuracy.
• Gives historical insight: It showcases a trend of drug usage over time, not just recent consumption.

Limitations:

• Cannot identify immediate use: Drugs become detectable in hair only after about 5-7 days.
• Expense: Hair drug testing is typically more costly compared to other drug testing methods.
• Result variability: Attributes like hair color and individual hair growth differences can influence the drug metabolite concentration in hair.

Note: Despite being commonly termed as "hair follicle tests", the analysis is conducted on the hair strand, not the follicle below 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.
