Hair Follicle Drug Testing - Benson, MN

What it is, How it works

The analysis of hair has gained recognition as an effective method for identifying the use of drugs and alcohol. Hair captures a prolonged history of substance use by embedding biomarkers within the strands as they grow. When hair is gathered near the scalp, it can offer a detection window of around three months for drugs and alcohol. The collection process is straightforward, and hair is relatively resistant to tampering and easy to transport.

A sample of hair measuring approximately 1.5 inches and consisting of about 200 strands near the scalp yields around 100mg, which is ideal for screening and confirmation purposes. For testing involving EtG, add-ons, or more than 10 panels, a 150mg sample is advisable. We suggest using a jeweler’s scale for measurement. If scalp hair isn't available, an equivalent quantity of body hair can be used. "Head hair" refers solely to scalp hair, while "body hair" encompasses all other hair types, such as facial or axillary hair.

Process Overview

The processing of drug test results entails four principal steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage where a sample is incorporated into a lab's system. The process includes checking that the sample was properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any manual data input not covered by the electronic chain of custody.

Screening is a preliminary, efficient method to detect drug abuse. While it is a cost-effective way to eliminate drug use in most samples, a positive result in Screening requires confirmation for legal acceptability. Any samples with presumptive positive results need a secondary confirmation stage.

If the Screening results suggest a positive sample, additional hair is taken from the initial sample for Extraction. This involves extracting drugs from hair at much lower concentrations than other methods like urine or oral fluid analysis, which is why performing hair drug screening is more challenging.

For any positive Screening outcomes, Confirmation is done using GC/MS, GC/MS/MS, or LC/MS/MS. Any samples requiring confirmation undergo washing as necessary. The laboratory procedures from Accessioning through Confirmation are assessed under both the CAP (College of American Pathologists) Hair criteria and the ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug tests can trace drug usage for up to 90 days, while urine tests have a shorter detection span.
• Difficult to manipulate: It's extremely challenging to tamper with a hair drug test, enhancing result accuracy.
• Shows usage patterns: It offers insights into long-term drug use patterns, beyond just recent use.

Limitations:

• Inability to detect recent use: Around 5-7 days are needed before drugs are traceable in hair.
• Expense: Generally, hair drug tests cost more than other testing methods.
• Result variability: Factors like hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Despite common terminology like "hair follicle tests," the examination focuses on the hair strand rather than the follicle beneath the skin.

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.
