Hair Follicle Drug Testing - Park Ridge, WI

What it is, How it works

Hair analysis is now recognized as an effective means for identifying alcohol and drug consumption. Hair retains a long-term record of alcohol and drug exposure by encapsulating biomarkers within the hair strand’s fibers. When taken near the scalp, hair can offer up to a three-month period for detecting alcohol and drugs. Collecting hair is straightforward, relatively tough to tamper with, and simple to transport.

A sample measuring 1.5 inches consisting of about 200 hair strands (approximately the thickness of a #2 pencil) closest to the scalp provides 100mg of hair, which is the optimal sample size for both screening and confirmation. For EtG, additional tests, and tests that exceed 10 panels, a specimen weight of 150mg is suggested. It is advised to use a jeweler’s scale to weigh the specimen. If scalp hair isn’t available, an equivalent quantity of body hair might be collected. References to head hair pertain specifically to scalp hair. Body hair includes all other hair types (e.g., facial, axillary).

Process Overview

The laboratory process of a drug test result includes Accessioning, Screening, Extraction, and Confirmation as its core steps.

Accessioning refers to the initial processing of a sample within a lab's framework, ensuring the sample was securely sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and completing any data entry absent from an electronic chain of custody system.

Screening involves a preliminary swift assessment for drugs. While it's a budget-friendly method to exclude drug presence in most samples, any positive result from Screening necessitates confirmation for legal admissibility. Samples that are tentatively positive in Screening need a subsequent confirmation.

In cases where a sample is tentatively positive during Screening, additional hair is extracted from the initial sample for Extraction. This phase involves isolating drugs from hair at considerably lower concentrations than other methods (such as urine or oral fluid), contributing to hair testing's complexity.

Confirmation for any preliminary positive result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples identified as presumptive positive undergo washing before confirmation if necessary. The complete lab process from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair designation and in alignment with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can identify drug usage for as long as 90 days, contrasting with urine tests that have a shorter detection timeframe.
• Hard to falsify: Hair drug tests are notably difficult to tamper with, enhancing result accuracy.
• Yields historical insight: It reveals a pattern of drug use over time, rather than just recent use.

Limitations:

• Inability to detect recent use: Detection in hair takes about 5-7 days post-consumption.
• Expense: Hair testing is generally pricier compared to other testing methods.
• Result variability: Factors like hair color and individual differences in hair growth can impact drug metabolite levels in hair.

Note: Though commonly termed "hair follicle tests", this analysis examines the hair strand and 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.
