Hair Follicle Drug Testing - Seneca, IL

What it is, How it works

Hair testing is increasingly viewed as an effective method for identifying drug and alcohol consumption. Hair captures long-term evidence of substance use by embedding biomarkers within the growing hair strand's fibers. When gathered near the scalp, hair can offer up to a three-month detection window for substances. Hair is easy to collect, hard to tamper with, and simple to transport.

Collecting a 1.5-inch segment of approximately 200 hair strands (similar to a #2 pencil thickness) from the scalp yields about 100mg of hair, which is the optimal sample size for screening and confirmation. For EtG, additional tests, and tests beyond 10 panels, 150mg of the sample is advisable. We suggest weighing the sample using a jeweler’s scale. If scalp hair is unavailable, a comparable amount of body hair may be used. When mentioning head hair, it refers exclusively to scalp hair. Body hair includes all other types (facial, axillary, etc.).

Process Overview

The lab processing of a drug test result entails four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial integration of a sample into a lab’s system. This step verifies that the sample was sealed and transported correctly, assigns a unique LAN (Laboratory Accessioning Number), and completes additional data input not covered by an electronic chain of custody system.

Screening involves a preliminary rapid assessment for drugs of abuse. While Screening is an economical approach to rule out drug use in most samples, a positive screen requires confirmation to be court admissible. Presumptive positives in Screening need further confirmation.

If Screening results are presumptively positive, more hair is extracted from the initial sample for the Extraction phase. During Extraction, drugs are isolated from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging to perform.

Confirmation of any positive screening outcome occurs via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed prior to confirmation as necessary. The full lab process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair program and the ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug exams reveal drug use up to 90 days, while urine tests have shorter detection durations.
• Challenging to manipulate: Cheating a hair drug test is difficult, ensuring accurate results.
• Shows usage history: It shows usage trends over time, rather than only recent usage.

Limitations:

• Inability to detect recent usage: It takes roughly 5-7 days for drugs to be traceable in hair.
• Expense: Hair drug exams are typically pricier than other testing methods.
• Variability in results: Factors such as hair color and individual hair growth variations can influence drug metabolite concentrations in hair.

Note: Often termed "hair follicle tests," the analysis focuses on the hair strand rather than 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.
