Hair Follicle Drug Testing - Round Lake, IL

What it is, How it works

Hair screening has emerged as an influential method for detecting drug and alcohol consumption. Hair provides an extended history of alcohol and other substances by enclosing biomarkers within the strands of growing hair. When collected near the scalp, hair can offer a detection timeframe of approximately three months for alcohol and other drugs. Hair is straightforward to collect, somewhat resistant to tampering, and simple to ship.

A 1.5-inch segment of around 200 hair strands (roughly the thickness of a #2 pencil) closest to the scalp provides 100mg of hair, the optimal sample for both screening and confirmation processes. For EtG testing, add-ons, and/or examinations exceeding 10 panels, 150mg of the specimen is suggested. We advise using a jeweler’s scale to weigh the specimen. If scalp hair is inaccessible, an equivalent amount of body hair might be collected. When discussing head hair, we specifically mean scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning covers the initial introduction of a sample into a laboratory's system, including verifying the proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and executing any supplementary data entry not supplied by an electronic chain of custody framework.

Screening entails a preliminary swift examination for drugs of misuse. While Screening is an economical approach to exclude drug usage in most samples, a positive screen must be confirmed for court admissibility. Samples indicating a presumptive positive in Screening necessitate secondary confirmation.

If a sample shows a presumptive positive during the Screening phase, further hair is taken from the initial sample and prepared for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), which accounts for the complexity of performing hair drug screening.

Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo washing prior to confirmation as required. The full laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair specification 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 with a shorter detection period.
• Challenge to falsify: Cheating a hair drug test is extremely challenging, rendering the results more reliable.
• Information on historical use: Hair tests can reveal a pattern of drug usage over time, rather than just recent consumption.

Limitations:

• Inability to detect recent use: Detection of drugs in hair takes around 5-7 days.
• Expense: Hair drug tests tend to be costlier than other drug testing methods.
• Result variability: Factors such as hair color and personal hair growth differences can influence drug metabolite concentrations in the hair.

Note: Often labeled as "hair follicle tests", the procedure actually examines 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.
