Hair Follicle Drug Testing - Sheffield, IA

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair serves as a long-term repository for these substances by embedding biomarkers within the hair strand's growing fibers. When collected close to the scalp, hair can reveal up to a 3-month window for detecting alcohol and other drugs. It is straightforward to collect, challenging to tamper with, and easy to send.

A 1.5-inch segment of around 200 hair strands (approximately the size of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the ideal sample for screening and confirmation. For EtG, add-ons, and tests exceeding 10 panels, a 150mg specimen is advisable. We suggest using a jeweler’s scale for weighing the specimen. If scalp hair is unavailable, an equivalent quantity of body hair can be collected. "Head hair" refers exclusively to scalp hair. "Body hair" includes all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the sample's initial processing into a laboratory’s system. This process includes confirming that the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and addressing any additional data entry not provided by an electronic chain of custody system.

Screening involves an initial rapid check for drugs of abuse. Although Screening is a cost-effective method to exclude drug usage on most samples, a positive screening result needs court-admissible confirmation. Any samples presumptively positive in Screening require a subsequent confirmation.

If a sample is presumptively positive during Screening, more hair is taken from the initial specimen and prepared for Extraction. In this stage, drugs are extracted from hair at a significantly lower concentration than other methodologies (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to execute.

Confirmation of any positive screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation as necessary. The complete laboratory sequence from Accessioning to Confirmation is reviewed under both CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter detection period.
• Difficult to tamper with: It is exceedingly challenging to falsify a hair drug test, enhancing result accuracy.
• Historical usage data: It provides a usage pattern over time, not just recent usage.

Limitations:

• Inability to detect recent usage: Drugs become noticeable in hair approximately 5-7 days after use.
• Cost: Hair drug tests generally incur higher expenses than other drug testing methods.
• Variable results: Elements like hair color and differences in individual hair growth can influence drug metabolite concentration in the hair.

Note: Although commonly called "hair follicle tests", the test 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.
