Hair Follicle Drug Testing - Carol Stream, IL

What it is, How it works

Hair testing has emerged as an effective tool for detecting drug and alcohol consumption. Hair captures alcohol and other drug biomarkers within the fibers of the hair strand as it grows, providing a long-term usage history. When gathered near the scalp, hair can offer a detection period of up to roughly 3 months for alcohol and drugs. Hair collection is straightforward, somewhat resistant to tampering, and easy to transport.

A sample measuring 1.5 inches of approximately 200 hair strands (equivalent to the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample amount for analysis and validation. For EtG, additional analyses, and/or tests exceeding 10 panels, 150mg of hair is advised. It's suggested to weigh the sample using a jeweler's scale. In cases where scalp hair isn't available, an equal quantity of body hair can be used. By head hair, we mean only scalp hair. Body hair encompasses any other type of hair (facial, axillary, etc.).

Process Overview

The laboratory process for drug test results involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step where a sample is logged into a lab's system. This step verifies if the sample was properly sealed and sent, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry absent from an electronic chain of custody system.

Screening offers a preliminary assessment for drugs of abuse. Although Screening is cost-effective to exclude drug use in most cases, any positive result must be confirmed for court admissibility. Samples that test positive in Screening require additional confirmation.

If a sample tests positive during Screening, more hair is extracted from the original sample and prepped for Extraction. In this stage, drugs are extracted from hair at much lower concentrations than other methods (such as urine or oral fluid), highlighting why hair drug screening is particularly challenging.

GC/MS, GC/MS/MS, or LC/MS/MS are methods employed for Confirming any positive Screening outcome. Any presumptive positive samples are cleansed before confirmation, as necessary. The complete process from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair guidelines and the ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests that have a shorter detection period.
• Resistance to tampering: Hair drug tests are hard to cheat, ensuring more reliable results.
• Historical use data: They can reveal drug usage over a long period, not just recent consumption.

Limitations:

• Inability to detect recent use: Drugs take about 5-7 days to be detectable in hair.
• Expense: Hair drug tests typically cost more than other testing methods.
• Result variability: Elements like hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Although often termed "hair follicle tests", the analysis is conducted on 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.
